https://github.com/huggingface/datasets/issues/625 | dtype of tensors should be preserved | Indeed we convert tensors to list to be able to write in arrow format. Because of this conversion we lose the dtype information. We should add the dtype detection when we do type inference. However it would require a bit of refactoring since currently the conversion happens before the type inference..
And then for your information, when reading from arrow format we have to cast from arrow to numpy (which is fast since pyarrow has a numpy integration), and then to torch.
However there's one thing that can help you: we make sure that the dtypes correspond to what is defined in `features`.
Therefore what you can do is provide `features` in `.map(preprocess, feature=...)` to specify the output types.
For example in your case:
```python
from datasets import Features, Value, Sequence
features = Features({
"input_ids": Sequence(Value("int32")),
"sembedding": Sequence(Value("float32"))
})
preprocessed_dataset = dataset.map(preprocess, features=features)
preprocessed_dataset.set_format("torch", columns=["input_ids", "sembedding"])
print(preprocessed_dataset[0]["sembedding"].dtype)
# "torch.float32"
```
Let me know if it helps | After switching to `datasets` my model just broke. After a weekend of debugging, the issue was that my model could not handle the double that the Dataset provided, as it expected a float (but didn't give a warning, which seems a [PyTorch issue](https://discuss.pytorch.org/t/is-it-required-that-input-and-hidden-for-gru-have-the-same-dtype-float32/96221)).
As a user I did not expect this bug. I have a `map` function that I call on the Dataset that looks like this:
```python
def preprocess(sentences: List[str]):
token_ids = [[vocab.to_index(t) for t in s.split()] for s in sentences]
sembeddings = stransformer.encode(sentences)
print(sembeddings.dtype)
return {"input_ids": token_ids, "sembedding": sembeddings}
```
Given a list of `sentences` (`List[str]`), it converts those into token_ids on the one hand (list of lists of ints; `List[List[int]]`) and into sentence embeddings on the other (Tensor of dtype `torch.float32`). That means that I actually set the column "sembedding" to a tensor that I as a user expect to be a float32.
It appears though that behind the scenes, this tensor is converted into a **list**. I did not find this documented anywhere but I might have missed it. From a user's perspective this is incredibly important though, because it means you cannot do any data_type or tensor casting yourself in a mapping function! Furthermore, this can lead to issues, as was my case.
My model expected float32 precision, which I thought `sembedding` was because that is what `stransformer.encode` outputs. But behind the scenes this tensor is first cast to a list, and when we then set its format, as below, this column is cast not to float32 but to double precision float64.
```python
dataset.set_format(type="torch", columns=["input_ids", "sembedding"])
```
This happens because apparently there is an intermediate step of casting to a **numpy** array (?) **whose dtype creation/deduction is different from torch dtypes** (see the snippet below). As you can see, this means that the dtype is not preserved: if I got it right, the dataset goes from torch.float32 -> list -> float64 (numpy) -> torch.float64.
```python
import torch
import numpy as np
l = [-0.03010837361216545, -0.035979013890028, -0.016949838027358055]
torch_tensor = torch.tensor(l)
np_array = np.array(l)
np_to_torch = torch.from_numpy(np_array)
print(torch_tensor.dtype)
# torch.float32
print(np_array.dtype)
# float64
print(np_to_torch.dtype)
# torch.float64
```
This might lead to unwanted behaviour. I understand that the whole library is probably built around casting from numpy to other frameworks, so this might be difficult to solve. Perhaps `set_format` should include a `dtypes` option where for each input column the user can specify the wanted precision.
The alternative is that the user needs to cast manually after loading data from the dataset but that does not seem user-friendly, makes the dataset less portable, and might use more space in memory as well as on disk than is actually needed. | 156 | dtype of tensors should be preserved

Casting from arrow to numpy can be 100x faster than casting from arrow to list.
This is because arrow has an integration with numpy that allows it to instantiate numpy arrays with zero-copy from arrow.
On the other hand to create python lists it is slow since it has to recreate the list object by iterating through each element in python. | After switching to `datasets` my model just broke.

https://github.com/huggingface/datasets/issues/625 | dtype of tensors should be preserved | I encountered a simliar issue: `datasets` converted my float numpy array to `torch.float64` tensors, while many pytorch operations require `torch.float32` inputs and it's very troublesome.
I tried @lhoestq 's solution, but since it's mixed with the preprocess function, it's not very intuitive.
I just want to share another possible simpler solution: directly cast the dtype of the processed dataset.
Now I want to change the type of `labels` in `train_dataset` from float64 to float32, I can do this.
```
from datasets import Value, Sequence, Features
feats = train_dataset.features.copy()
feats['labels'].feature = Value(dtype='float32')

I encountered a simliar issue: `datasets` converted my float numpy array to `torch.float64` tensors, while many pytorch operations require `torch.float32` inputs and it's very troublesome.
I tried @lhoestq 's solution, but since it's mixed with the preprocess function, it's not very intuitive.
I just want to share another possible simpler solution: directly cast the dtype of the processed dataset.
Now I want to change the type of `labels` in `train_dataset` from float64 to float32, I can do this.
```
from datasets import Value, Sequence, Features
feats = train_dataset.features.copy()
feats['labels'].feature = Value(dtype='float32')
feats = Features(feats)
train_dataset.cast_(feats)
```

Also I'm posting here a function that could be helpful to support preserving the dtype of tensors.
It's used to build a pyarrow array out of a numpy array and:
- it doesn't convert the numpy array to a python list
- it keeps the precision of the numpy array for the pyarrow array
- it works with multidimensional arrays (while `pa.array` can only take a 1D array as input)
- it builds the pyarrow ListArray from offsets created on-the-fly and values that come from the flattened numpy array
```python
from functools import reduce
from operator import mul
import numpy as np
import pyarrow as pa
def pa_ndarray(a):
"""Build a PyArrow ListArray from a multidimensional NumPy array"""
values = pa.array(a.flatten())
for i in range(a.ndim - 1):
n_offsets = reduce(mul, a.shape[:a.ndim - i - 1], 1)
step_offsets = a.shape[a.ndim - i - 1]
offsets = pa.array(np.arange(n_offsets + 1) * step_offsets, type=pa.int32())
values = pa.ListArray.from_arrays(offsets, values)
return values
narr = np.arange(42).reshape(7, 2, 3).astype(np.uint8)
parr = pa_ndarray(narr)
assert isinstance(parr, pa.Array)
assert parr.type == pa.list_(pa.list_(pa.uint8()))
assert narr.tolist() == parr.to_pylist()
```
The only costly operation is the offsets computations. Since it doesn't iterate on the numpy array values this function is pretty fast. | After switching to `datasets` my model just broke. After a weekend of debugging, the issue was that my model could not handle the double that the Dataset provided, as it expected a float (but didn't give a warning, which seems a [PyTorch issue](https://discuss.pytorch.org/t/is-it-required-that-input-and-hidden-for-gru-have-the-same-dtype-float32/96221)).
As a user I did not expect this bug. I have a `map` function that I call on the Dataset that looks like this:
```python
def preprocess(sentences: List[str]):
token_ids = [[vocab.to_index(t) for t in s.split()] for s in sentences]
sembeddings = stransformer.encode(sentences)
print(sembeddings.dtype)
return {"input_ids": token_ids, "sembedding": sembeddings}
```
Given a list of `sentences` (`List[str]`), it converts those into token_ids on the one hand (list of lists of ints; `List[List[int]]`) and into sentence embeddings on the other (Tensor of dtype `torch.float32`). That means that I actually set the column "sembedding" to a tensor that I as a user expect to be a float32.
It appears though that behind the scenes, this tensor is converted into a **list**. I did not find this documented anywhere but I might have missed it. From a user's perspective this is incredibly important though, because it means you cannot do any data_type or tensor casting yourself in a mapping function! Furthermore, this can lead to issues, as was my case.
My model expected float32 precision, which I thought `sembedding` was because that is what `stransformer.encode` outputs. But behind the scenes this tensor is first cast to a list, and when we then set its format, as below, this column is cast not to float32 but to double precision float64.
```python
dataset.set_format(type="torch", columns=["input_ids", "sembedding"])
```
This happens because apparently there is an intermediate step of casting to a **numpy** array (?) **whose dtype creation/deduction is different from torch dtypes** (see the snippet below). As you can see, this means that the dtype is not preserved: if I got it right, the dataset goes from torch.float32 -> list -> float64 (numpy) -> torch.float64.
```python
import torch
import numpy as np
l = [-0.03010837361216545, -0.035979013890028, -0.016949838027358055]

We have a use case where we're attempting to load data containing numpy arrays using the `datasets` library.
When using one of the "standard" methods (`[Value(...)]` or `Sequence()`) we see ~200 samples processed per second during the call to `_prepare_split`. This slowdown is caused by the vast number of calls to `encode_nested_example` (each sequence is converted to a list, and each element in the sequence...).
Using the `Feature` `ArrayND` improves this somewhat to ~500/s as it now uses numpy's `tolist()` rather than iterating over each value in the array and converting them individually.
However, it's still pretty slow and in theory it should be possible to avoid the `numpy -> python -> arrow` dance altogether. To demonstrate this, if you keep the `Feature` set to an `ArrayND` but instead return a `pa_ndarray(...)` in `_generate_examples` it skips the conversion (`return obj, False`) and hits ~11_000/s. Two orders of magnitude speed up! The problem is this then fails later on when the `ArrowWriter` tries to write the examples to disk :-(
It would be nice to have first-class support for user-defined PyArrow objects. Is this a possibility? We have _large_ datasets where even an order of magnitude difference is important so settling on the middle ~500/s is less than ideal!
Is there a workaround for this or another method that should be used instead that gets near-to or equal performance to returning PyArrow arrays? | After switching to `datasets` my model just broke.

Currently `csv` doesn't support the `features` attribute (unlike `json`).
What you can do for now is cast the features using the in-place transform `cast_`
```python
from datasets import load_dataset
dataset = load_dataset('csv', data_files=file_dict, delimiter=';', column_names=['text', 'label'])
dataset.cast_(emotion_features)
```

I am trying to load a local file with the `load_dataset` function and I want to predefine the feature types with the `features` argument. However, the types are always the same independent of the value of `features`.
I am working with the local files from the emotion dataset. To get the data you can use the following code:
```Python
from pathlib import Path
import wget
EMOTION_PATH = Path("./data/emotion")
DOWNLOAD_URLS = [
"https://www.dropbox.com/s/1pzkadrvffbqw6o/train.txt?dl=1",
"https://www.dropbox.com/s/2mzialpsgf9k5l3/val.txt?dl=1",
"https://www.dropbox.com/s/ikkqxfdbdec3fuj/test.txt?dl=1",
]
if not Path.is_dir(EMOTION_PATH):
Path.mkdir(EMOTION_PATH)
for url in DOWNLOAD_URLS:
wget.download(url, str(EMOTION_PATH))
```
The first five lines of the train set are:
```
i didnt feel humiliated;sadness
i can go from feeling so hopeless to so damned hopeful just from being around someone who cares and is awake;sadness
im grabbing a minute to post i feel greedy wrong;anger
i am ever feeling nostalgic about the fireplace i will know that it is still on the property;love
i am feeling grouchy;anger
```
Here the code to reproduce the issue:
```Python
from datasets import Features, Value, ClassLabel, load_dataset
class_names = ["sadness", "joy", "love", "anger", "fear", "surprise"]
emotion_features = Features({'text': Value('string'), 'label': ClassLabel(names=class_names)})
file_dict = {'train': EMOTION_PATH/'train.txt'}
dataset = load_dataset('csv', data_files=file_dict, delimiter=';', column_names=['text', 'label'], features=emotion_features)
```
**Observed behaviour:**
```Python
dataset['train'].features
```
```Python
{'text': Value(dtype='string', id=None),
'label': Value(dtype='string', id=None)}
```
**Expected behaviour:**
```Python
dataset['train'].features
```
```Python
{'text': Value(dtype='string', id=None),
'label': ClassLabel(num_classes=6, names=['sadness', 'joy', 'love', 'anger', 'fear', 'surprise'], names_file=None, id=None)}
```
**Things I've tried:**
- deleting the cache
- trying other types such as `int64`
Am I missing anything? Thanks for any pointer in the right direction.
PR is open for the `ValueError: Target schema's field names are not matching the table's field names` error.

| 120 | load_dataset for text files not working
Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

Downgrading to 3.7 does not help. Here is a dummy text file:
```text
Verzekering weigert vaker te betalen
Bedrijven van verzekeringen erkennen steeds minder arbeidsongevallen .
In 2012 weigerden de bedrijven te betalen voor 21.055 ongevallen op het werk .
Dat is 11,8 % van alle ongevallen op het werk .
Nog nooit weigerden verzekeraars zoveel zaken .
In 2012 hadden 135.118 mensen een ongeval op het werk .
Dat zijn elke werkdag 530 mensen .
Bij die ongevallen stierven 67 mensen .
Bijna 12.000 hebben een handicap na het ongeval .
Geen echt arbeidsongeval Bedrijven moeten een verzekering hebben voor hun werknemers .
```
A temporary work around for the "text" type, is
```python
dataset = Dataset.from_dict({"text": Path(dataset_f).read_text().splitlines()})

https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | I have the same problem on Linux of the script crashing with a CSV error. This may be caused by 'CRLF', when changed 'CRLF' to 'LF', the problem solved. | Trying the following snippet, I get different problems on Linux and Windows.

Same for you @BramVanroy .
Not sure about the one on linux though | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

Linux here:
I was using the 0.4.0 nlp library load_dataset to load a text dataset of 9-10Gb without collapsing the RAM memory. However, today I got the csv error message mentioned in this issue. After installing the new (datasets) library from source and specifying the script_verson = 'master' I'm still having this same error message. Furthermore, I cannot use the dictionary "trick" to load the dataset since the system kills the process due to a RAM out of memory problem. Is there any other solution to this error? Thank you in advance. | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | Hi @raruidol
To fix the RAM issue you'll need to shard your text files into smaller files (see https://github.com/huggingface/datasets/issues/610#issuecomment-691672919 for example)
I'm not sure why you're having the csv error on linux.
Do you think you could to to reproduce it on google colab for example ?
Or send me a dummy .txt file that reproduces the issue ? | Trying the following snippet, I get different problems on Linux and Windows.
```python

Hi @raruidol
To fix the RAM issue you'll need to shard your text files into smaller files (see https://github.com/huggingface/datasets/issues/610#issuecomment-691672919 for example)
I'm not sure why you're having the csv error on linux.
Do you think you could to to reproduce it on google colab for example ?
Or send me a dummy .txt file that reproduces the issue ? |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | @lhoestq
The crash message shows up when loading the dataset:
```
print('Loading corpus...')
files = glob.glob('corpora/shards/*')
-> dataset = load_dataset('text', script_version='master', data_files=files)
print('Corpus loaded.')
```
And this is the exact message:
```

```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)

https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | I tested on google colab which is also linux using this code:
- first download an arbitrary text file
```bash
wget https://raw.githubusercontent.com/abisee/cnn-dailymail/master/url_lists/all_train.txt
```
- then run
```python
from datasets import load_dataset
d = load_dataset("text", data_files="all_train.txt", script_version='master')
```
And I don't get this issue.
\> Could you test on your side if these lines work @raruidol ?
also cc @Skyy93 as it seems you have the same issue
If it works:
It could mean that the issue could come from unexpected patterns in the files you want to use.
In that case we should find a way to handle them.
And if it doesn't work:
It could mean that it comes from the way pyarrow reads text files on linux.
In that case we should report it to pyarrow and find a workaround in the meantime
Either way it should help to find where this bug comes from and fix it :)
Thank you in advance ! | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)

It looks like with your text input file works without any problem. I have been doing some experiments this morning with my input files and I'm almost certain that the crash is caused by some unexpected pattern in the files. However, I've not been able to spot the main cause of it. What I find strange is that this same corpus was being loaded by the nlp 0.4.0 library without any problem... Where can I find the code where you structure the input text data in order to use it with pyarrow? |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | Under the hood it does
```python
import pyarrow as pa
import pyarrow.csv
# Use csv reader from Pyarrow with one column for text files
# To force the one-column setting, we set an arbitrary character
# that is not in text files as delimiter, such as \b or \v.
# The bell character, \b, was used to make beeps back in the days
parse_options = pa.csv.ParseOptions(
delimiter="\b",
quote_char=False,
double_quote=False,
escape_char=False,
newlines_in_values=False,
ignore_empty_lines=False,
)
read_options= pa.csv.ReadOptions(use_threads=True, column_names=["text"])
pa_table = pa.csv.read_csv("all_train.txt", read_options=read_options, parse_options=parse_options)
```
Note that we changed the parse options with datasets 1.0
In particular the delimiter used to be `\r` but this delimiter doesn't work on windows. | Trying the following snippet, I get different problems on Linux and Windows.

| 107 | load_dataset for text files not working
Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

# Use csv reader from Pyarrow with one column for text files
# To force the one-column setting, we set an arbitrary character
# that is not in text files as delimiter, such as \b or \v.

Note that we changed the parse options with datasets 1.0

Could you try with `\a` instead of `\b` ? It looks like the bell character is \a in python and not \b |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | I was just exploring if the crash was happening in every shard or not, and which shards were generating the error message. With \b I got the following list of shards crashing:

Which means that it is quite possible that the assumption of that some unexpected pattern in the files is causing the crashes is true. If I am able to reach any conclusion I will post It here asap. | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

Which means that it is quite possible that the assumption of that some unexpected pattern in the files is causing the crashes is true. If I am able to reach any conclusion I will post It here asap. |

Hi @lhoestq, is there any input length restriction which was not before the update of the nlp library? |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | No we never set any input length restriction on our side (maybe arrow but I don't think so) | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

No we never set any input length restriction on our side (maybe arrow but I don't think so) |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | @lhoestq Can you ever be certain that a delimiter character is not present in a plain text file? In other formats (e.g. CSV) , rules are set of what is allowed and what isn't so that it actually constitutes a CSV file. In a text file you basically have "anything goes", so I don't think you can ever be entirely sure that the chosen delimiter does not exist in the text file, or am I wrong?
If I understand correctly you choose a delimiter that we hope does not exist in the file, so that when the CSV parser starts splitting into columns, it will only ever create one column? Why can't we use a newline character though? | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)

@lhoestq Can you ever be certain that a delimiter character is not present in a plain text file? In other formats (e.g. CSV) , rules are set of what is allowed and what isn't so that it actually constitutes a CSV file. In a text file you basically have "anything goes", so I don't think you can ever be entirely sure that the chosen delimiter does not exist in the text file, or am I wrong?
If I understand correctly you choose a delimiter that we hope does not exist in the file, so that when the CSV parser starts splitting into columns, it will only ever create one column? Why can't we use a newline character though? |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | Okay, I have splitted the crashing shards into individual sentences and some examples of the inputs that are causing the crashes are the following ones:
_4. DE L’ORGANITZACIÓ ESTAMENTAL A L’ORGANITZACIÓ EN CLASSES A mesura que es desenvolupava un sistema econòmic capitalista i naixia una classe burgesa cada vegada més preparada per a substituir els dirigents de les velles monarquies absolutistes, es qüestionava l’abundància de béns amortitzats, que com s’ha dit estaven fora del mercat i no pagaven tributs, pels perjudicis que ocasionaven a les finances públiques i a l’economia en general. Aquest estat d’opinió revolucionari va desembocar en un conjunt de mesures pràctiques de caràcter liberal. D’una banda, les que intentaven desposseir les mans mortes del domini de béns acumulats, procés que acostumem a denominar desamortització, i que no és més que la nacionalització i venda d’aquests béns eclesiàstics o civils en subhasta pública al millor postor. D’altra banda, les que redimien o reduïen els censos i delmes o aixecaven les prohibicions de venda, és a dir, les vinculacions. La desamortització, que va afectar béns dels ordes religiosos, dels pobles i d’algunes corporacions civils, no va ser un camí fàcil, perquè costava i costa trobar algú que sigui indiferent a la pèrdua de béns, drets i privilegis. I té una gran transcendència, va privar els antics estaments de les Espanyes, clero i pobles —la noblesa en queda al marge—, de la força econòmica que els donaven bona part de les seves terres i, en última instància, va preparar el terreny per a la substitució de la vella societat estamental per la nova societat classista. En aquesta societat, en teoria, les agrupacions socials són obertes, no tenen cap estatut jurídic privilegiat i estan definides per la possessió o no d’uns béns econòmics que són lliurement alienables. A les Espanyes la transformació va afectar poc l’aristocràcia latifundista, allà on n’hi havia. Aquesta situació va afavorir, en part, la persistència de la vella cultura de la societat estamental en determinats ambients, i això ha influït decisivament en la manca de democràcia que caracteritza la majoria de règims polítics que s’han anat succeint. Una manera de pensar que sempre sura en un moment o altre, i que de fet no acaba de desaparèixer del tot. 5. INICI DE LA DESAMORTITZACIÓ A LES ESPANYES Durant el segle xviii, dins d’aquesta visió lliberal, va agafar força en alguns cercles de les Espanyes el corrent d’opinió contrari a les mans mortes. Durant el regnat de Carles III, s’arbitraren les primeres mesures desamortitzadores proposades per alguns ministres il·lustrats. Aquestes disposicions foren modestes i poc eficaces, no van aturar l’acumulació de terres per part dels estaments que constituïen les mans mortes i varen afectar principalment béns dels pobles. L’Església no va ser tocada, excepte en el cas de 110_
_la revolució liberal, perquè, encara que havia perdut els seus drets jurisdiccionals, havia conservat la majoria de terres i fins i tot les havia incrementat amb d’altres que procedien de la desamortització. En la nova situació, les mans mortes del bosc públic eren l’Estat, que no cerca mai l’autofinançament de les despeses de gestió; els diners que manquin ja els posarà l’Estat. 9. DEFENSA I INTENTS DE RECUPERACIÓ DELS BÉNS COMUNALS DESAMORTITZATS El procés de centralització no era senzill, perquè, d’una banda, la nova organització apartava de la gestió moltes corporacions locals i molts veïns que l’havien portada des de l’edat mitjana, i, de l’altra, era difícil de coordinar la nova silvicultura amb moltes pràctiques forestals i drets tradicionals, com la pastura, fer llenya o tallar un arbre aquí i un altre allà quan tenia el gruix suficient, les pràctiques que s’havien fet sempre. Les primeres passes de la nova organització centralitzada varen tenir moltes dificultats en aquells indrets en què els terrenys municipals i comunals tenien un paper important en l’economia local. La desobediència a determinades normes imposades varen prendre formes diferents. Algunes institucions, com, per exemple, la Diputació de Lleida, varen retardar la tramitació d’alguns expedients i varen evitar la venda de béns municipals. Molts pobles permeteren deixar que els veïns continuessin amb les seves pràctiques tradicionals, d’altres varen boicotejar les subhastes d’aprofitaments. L’Estat va reaccionar encomanant a la Guàrdia Civil el compliment de les noves directrius. Imposar el nou règim va costar a l’Administració un grapat d’anys, però de mica en mica, amb molta, molta guarderia i gens de negociació, ho va aconseguir. La nova gestió estatal dels béns municipals va deixar, com hem comentat, molta gent sense uns recursos necessaris per a la supervivència, sobre tot en àrees on predominaven les grans propietats, i on els pagesos sense terra treballaven de jornalers temporers. Això va afavorir que, a bona part de les Espanyes, les primeres lluites camperoles de la segona meitat del segle xix defensessin la recuperació dels comunals desamortitzats; per a molts aquella expropiació i venda dirigida pels governs monàrquics era la causa de molta misèria. D’altres, més radicalitzats, varen entendre que l’eliminació de la propietat col·lectiva i la gestió estatal dels boscos no desamortitzats suposava una usurpació pura i dura. En les zones més afectades per la desamortització això va donar lloc a un imaginari centrat en la defensa del comunal. La Segona República va arribar en una conjuntura econòmica de crisi, generada pel crac del 1929. Al camp, aquesta situació va produir una forta caiguda dels preus dels productes agraris i un increment important de l’atur. QUADERNS AGRARIS 42 (juny 2017), p. 105-126_

Okay, I have splitted the crashing shards into individual sentences and some examples of the inputs that are causing the crashes are the following ones:
_4. DE L’ORGANITZACIÓ ESTAMENTAL A L’ORGANITZACIÓ EN CLASSES A mesura que es desenvolupava un sistema econòmic capitalista i naixia una classe burgesa cada vegada més preparada per a substituir els dirigents de les velles monarquies absolutistes, es qüestionava l’abundància de béns amortitzats, que com s’ha dit estaven fora del mercat i no pagaven tributs, pels perjudicis que ocasionaven a les finances públiques i a l’economia en general. Aquest estat d’opinió revolucionari va desembocar en un conjunt de mesures pràctiques de caràcter liberal. D’una banda, les que intentaven desposseir les mans mortes del domini de béns acumulats, procés que acostumem a denominar desamortització, i que no és més que la nacionalització i venda d’aquests béns eclesiàstics o civils en subhasta pública al millor postor. D’altra banda, les que redimien o reduïen els censos i delmes o aixecaven les prohibicions de venda, és a dir, les vinculacions. La desamortització, que va afectar béns dels ordes religiosos, dels pobles i d’algunes corporacions civils, no va ser un camí fàcil, perquè costava i costa trobar algú que sigui indiferent a la pèrdua de béns, drets i privilegis. I té una gran transcendència, va privar els antics estaments de les Espanyes, clero i pobles —la noblesa en queda al marge—, de la força econòmica que els donaven bona part de les seves terres i, en última instància, va preparar el terreny per a la substitució de la vella societat estamental per la nova societat classista. En aquesta societat, en teoria, les agrupacions socials són obertes, no tenen cap estatut jurídic privilegiat i estan definides per la possessió o no d’uns béns econòmics que són lliurement alienables. A les Espanyes la transformació va afectar poc l’aristocràcia latifundista, allà on n’hi havia. Aquesta situació va afavorir, en part, la persistència de la vella cultura de la societat estamental en determinats ambients, i això ha influït decisivament en la manca de democràcia que caracteritza la majoria de règims polítics que s’han anat succeint. Una manera de pensar que sempre sura en un moment o altre, i que de fet no acaba de desaparèixer del tot. 5. INICI DE LA DESAMORTITZACIÓ A LES ESPANYES Durant el segle xviii, dins d’aquesta visió lliberal, va agafar força en alguns cercles de les Espanyes el corrent d’opinió contrari a les mans mortes. Durant el regnat de Carles III, s’arbitraren les primeres mesures desamortitzadores proposades per alguns ministres il·lustrats. Aquestes disposicions foren modestes i poc eficaces, no van aturar l’acumulació de terres per part dels estaments que constituïen les mans mortes i varen afectar principalment béns dels pobles. L’Església no va ser tocada, excepte en el cas de 110_
_la revolució liberal, perquè, encara que havia perdut els seus drets jurisdiccionals, havia conservat la majoria de terres i fins i tot les havia incrementat amb d’altres que procedien de la desamortització. En la nova situació, les mans mortes del bosc públic eren l’Estat, que no cerca mai l’autofinançament de les despeses de gestió; els diners que manquin ja els posarà l’Estat. 9. DEFENSA I INTENTS DE RECUPERACIÓ DELS BÉNS COMUNALS DESAMORTITZATS El procés de centralització no era senzill, perquè, d’una banda, la nova organització apartava de la gestió moltes corporacions locals i molts veïns que l’havien portada des de l’edat mitjana, i, de l’altra, era difícil de coordinar la nova silvicultura amb moltes pràctiques forestals i drets tradicionals, com la pastura, fer llenya o tallar un arbre aquí i un altre allà quan tenia el gruix suficient, les pràctiques que s’havien fet sempre. Les primeres passes de la nova organització centralitzada varen tenir moltes dificultats en aquells indrets en què els terrenys municipals i comunals tenien un paper important en l’economia local. La desobediència a determinades normes imposades varen prendre formes diferents. Algunes institucions, com, per exemple, la Diputació de Lleida, varen retardar la tramitació d’alguns expedients i varen evitar la venda de béns municipals. Molts pobles permeteren deixar que els veïns continuessin amb les seves pràctiques tradicionals, d’altres varen boicotejar les subhastes d’aprofitaments. L’Estat va reaccionar encomanant a la Guàrdia Civil el compliment de les noves directrius. Imposar el nou règim va costar a l’Administració un grapat d’anys, però de mica en mica, amb molta, molta guarderia i gens de negociació, ho va aconseguir. La nova gestió estatal dels béns municipals va deixar, com hem comentat, molta gent sense uns recursos necessaris per a la supervivència, sobre tot en àrees on predominaven les grans propietats, i on els pagesos sense terra treballaven de jornalers temporers. Això va afavorir que, a bona part de les Espanyes, les primeres lluites camperoles de la segona meitat del segle xix defensessin la recuperació dels comunals desamortitzats; per a molts aquella expropiació i venda dirigida pels governs monàrquics era la causa de molta misèria. D’altres, més radicalitzats, varen entendre que l’eliminació de la propietat col·lectiva i la gestió estatal dels boscos no desamortitzats suposava una usurpació pura i dura. En les zones més afectades per la desamortització això va donar lloc a un imaginari centrat en la defensa del comunal. La Segona República va arribar en una conjuntura econòmica de crisi, generada pel crac del 1929. Al camp, aquesta situació va produir una forta caiguda dels preus dels productes agraris i un increment important de l’atur. QUADERNS AGRARIS 42 (juny 2017), p. 105-126_
I think that the main difference between the crashing samples and the rest is their length. Therefore, couldn't the length be causing the message errors? I hope with these samples you can identify what is causing the crashes considering that the 0.4.0 nlp library was loading them properly. |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | So we're using the csv reader to read text files because arrow doesn't have a text reader.
To workaround the fact that text files are just csv with one column, we want to set a delimiter that doesn't appear in text files.
Until now I thought that it would do the job but unfortunately it looks like even characters like \a appear in text files.
So we have to option:
- find another delimiter that does the job (maybe `\x1b` esc or `\x18` cancel)
- don't use the csv reader from arrow but the text reader from pandas instead (or any other reader). The only important thing is that it must be fast (arrow's reader has a nice and fast multithreaded for csv that we're using now but hopefully we can find an alternative)
> @lhoestq Can you ever be certain that a delimiter character is not present in a plain text file? In other formats (e.g. CSV) , rules are set of what is allowed and what isn't so that it actually constitutes a CSV file. In a text file you basically have "anything goes", so I don't think you can ever be entirely sure that the chosen delimiter does not exist in the text file, or am I wrong?
As long as the text file follows some encoding it wouldn't make sense to have characters such as the bell character. However I agree it can happen.
> If I understand correctly you choose a delimiter that we hope does not exist in the file, so that when the CSV parser starts splitting into columns, it will only ever create one column? Why can't we use a newline character though?
Exactly. Arrow doesn't allow the newline character unfortunately. | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

So we're using the csv reader to read text files because arrow doesn't have a text reader.
To workaround the fact that text files are just csv with one column, we want to set a delimiter that doesn't appear in text files.
Until now I thought that it would do the job but unfortunately it looks like even characters like \a appear in text files.
So we have to option:
- find another delimiter that does the job (maybe `\x1b` esc or `\x18` cancel)
- don't use the csv reader from arrow but the text reader from pandas instead (or any other reader). The only important thing is that it must be fast (arrow's reader has a nice and fast multithreaded for csv that we're using now but hopefully we can find an alternative)
> @lhoestq Can you ever be certain that a delimiter character is not present in a plain text file? In other formats (e.g. CSV) , rules are set of what is allowed and what isn't so that it actually constitutes a CSV file. In a text file you basically have "anything goes", so I don't think you can ever be entirely sure that the chosen delimiter does not exist in the text file, or am I wrong?
As long as the text file follows some encoding it wouldn't make sense to have characters such as the bell character. However I agree it can happen.
> If I understand correctly you choose a delimiter that we hope does not exist in the file, so that when the CSV parser starts splitting into columns, it will only ever create one column? Why can't we use a newline character though?
Exactly. Arrow doesn't allow the newline character unfortunately. |
https://github.com/huggingface/datasets/issues/622 | load_dataset for text files not working | > Okay, I have splitted the crashing shards into individual sentences and some examples of the inputs that are causing the crashes are the following ones
Thanks for digging into it !
Characters like \a or \b are not shown when printing the text, so as it is I can't tell if it contains unexpected characters.
Maybe could could open the file in python and check if `"\b" in open("path/to/file", "r").read()` ?
> I think that the main difference between the crashing samples and the rest is their length. Therefore, couldn't the length be causing the message errors? I hope with these samples you can identify what is causing the crashes considering that the 0.4.0 nlp library was loading them properly.
To check that you could try to run
```python
import pyarrow as pa
import pyarrow.csv
open("dummy.txt", "w").write((("a" * 10_000) + "\n") * 4) # 4 lines of 10 000 'a'
parse_options = pa.csv.ParseOptions(
delimiter="\b",
quote_char=False,
double_quote=False,
escape_char=False,
newlines_in_values=False,
ignore_empty_lines=False,
)
read_options= pa.csv.ReadOptions(use_threads=True, column_names=["text"])
pa_table = pa.csv.read_csv("dummy.txt", read_options=read_options, parse_options=parse_options)
```
on my side it runs without error though | Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

| 28 | load_dataset for text files not working
Trying the following snippet, I get different problems on Linux and Windows.
```python
dataset = load_dataset("text", data_files="data.txt")
# or
dataset = load_dataset("text", data_files=["data.txt"])
```
(ps [This example](https://huggingface.co/docs/datasets/loading_datasets.html#json-files) shows that you can use a string as input for data_files, but the signature is `Union[Dict, List]`.)
The problem on Linux is that the script crashes with a CSV error (even though it isn't a CSV file). On Windows the script just seems to freeze or get stuck after loading the config file.

I don't think it would work since we only want one column, and "\b" is set to be the delimiter between two columns, so it will raise the same issue again. Pyarrow would think that there is more than one column if the delimiter is found somewhere.
Anyway, I I'll work on a new text reader if we don't find the right workaround about this delimiter issue. | Trying the following snippet, I get different problems on Linux and Windows.

I'm running this on MACOS the version of datasets I'm was 1.0.0 but I've also tried it on 1.0.2. `pyarrow==1.0.1`, Python 3.6
Consider this code:
```python
loader_path = str(Path(__file__).parent / "prodigy_dataset_builder.py")
ds = load_dataset(
loader_path, name="prodigy-ds", data_files=list(file_paths), cache_dir=cache_dir
)["train"]
valid_relations = set(vocabulary.relation_types.keys())
ds = ds.filter(filter_good_rows, fn_kwargs=dict(valid_rel_labels=valid_relations))
ds = ds.map(map_bpe_encodings, batched=True, fn_kwargs=dict(tokenizer=vocabulary.tokenizer), num_proc=10)
# add all feature data
ner_ds: Dataset = ds.map(
add_bio_tags,
fn_kwargs=dict(ner_label_map=vocabulary.ner_labels, tokenizer=vocabulary.tokenizer),

rel_ds: Dataset = ner_ds.map(
relation_ds_factory,
batched=True,
writer_batch_size=100,
fn_kwargs=dict(tokenizer=vocabulary.tokenizer, vocabulary=vocabulary),
)
```
The loader is essentially a jsonloader with some extra error handling. The data is a jsonlines format with text field and a list of span objects and relation objects.
In the `ner_ds` a field, `ner_labels` is added, this is used in the downstream `relation_ds_factory`. It all runs fine in a single process but I get a KeyError error if run with num_proc set
:
```

ner_labels = example["ner_labels"]
KeyError: 'ner_labels'
```
This is just one example of what goes wrong. I've started just saving the dataset as arrow at the end because it takes a long time to map/filter/shuffle and the caching isn't working (tracked it down to byte differences in the pickled functions).
^^ Interestingly if I heed the warning from Tokenizers and set the environment variable, `TOKENIZERS_PARALLELISM=true` the map just hangs:

https://github.com/huggingface/datasets/issues/620 | map/filter multiprocessing raises errors and corrupts datasets | #659 should fix the `KeyError` issue. It was due to the formatting not getting updated the right way | After upgrading to the 1.0 started seeing errors in my data loading script after enabling multiprocessing.
```python
...
ner_ds_dict = ner_ds.train_test_split(test_size=test_pct, shuffle=True, seed=seed)
ner_ds_dict["validation"] = ner_ds_dict["test"]
rel_ds_dict = rel_ds.train_test_split(test_size=test_pct, shuffle=True, seed=seed)
rel_ds_dict["validation"] = rel_ds_dict["test"]
return ner_ds_dict, rel_ds_dict
```
The first train_test_split, `ner_ds`/`ner_ds_dict`, returns a `train` and `test` split that are iterable.
The second, `rel_ds`/`rel_ds_dict` in this case, returns a Dataset dict that has rows but if selected from or sliced into into returns an empty dictionary. eg `rel_ds_dict['train'][0] == {}` and `rel_ds_dict['train'][0:100] == {}`.
Ok I think I know the problem -- the rel_ds was mapped though a mapper with `num_proc=12`. If I remove `num_proc`. The dataset loads.
I also see errors with other map and filter functions when `num_proc` is set.

To disable this warning, you can either:
- Avoid using `tokenizers` before the fork if possible
- Explicitly set the environment variable TOKENIZERS_PARALLELISM=(true | false)

So if possible, the tokenizers shouldn't be used before the fork, so that each process can then make use of the parallelism. Otherwise using `TOKENIZERS_PARALLELISM=false` is the way to go. |

https://github.com/huggingface/datasets/issues/620 | map/filter multiprocessing raises errors and corrupts datasets | Hi @lhoestq ,
Thanks for letting me know about the update.
So I don't think it's the caching - because hashing mechanism isn't stable for me -- but that's a different issue. In any case I `rm -rf ~/.cache/huggingface` to make a clean slate.
I synced with master and I see the key error has gone away, I tried with and without the `TOKENIZERS_PARALLELISM` variable set and see the log line for setting the value false before the map.
Now I'm seeing an issue with `.train_test_split()` on datasets that are the product of a multiprocess map.

https://github.com/huggingface/datasets/issues/619 | Mistakes in MLQA features names | Indeed you're right ! Thanks for reporting that
Could you open a PR to fix the features names ? | I think the following features in MLQA shouldn't be named the way they are:
1. `questions` (should be `question`)
2. `ids` (should be `id`)
3. `start` (should be `answer_start`)
The reasons I'm suggesting these features be renamed are:
* To make them consistent with other QA datasets like SQuAD, XQuAD, TyDiQA etc. and hence make it easier to concatenate multiple QA datasets.
* The features names are not the same as the ones provided in the original MLQA datasets (it uses the names I suggested).
I know these columns can be renamed using using `Dataset.rename_column_`, `questions` and `ids` can be easily renamed but `start` on the other hand is annoying to rename since it's nested inside the feature `answers`.

https://github.com/huggingface/datasets/issues/617 | Compare different Rouge implementations | Updates - the differences between the following three
(1) https://github.com/bheinzerling/pyrouge (previously popular. The one I trust the most)
(2) https://github.com/google-research/google-research/tree/master/rouge
(3) https://github.com/pltrdy/files2rouge (used in fairseq)
can be explained by two things, stemming and handling multiple sentences.
Stemming:
(1), (2): default is no stemming. (3): default is with stemming ==> No stemming is the correct default as you did [here](https://github.com/huggingface/datasets/blob/master/metrics/rouge/rouge.py#L84)
Multiple sentences:
(1) `rougeL` splits text using `\n`
(2) `rougeL` ignores `\n`.
(2) `rougeLsum` splits text using `\n`
(3) `rougeL` splits text using `.`
For (2), `rougeL` and `rougeLsum` are identical if the sequence doesn't contain `\n`. With `\n`, it is `rougeLsum` that matches (1) not `rougeL`.
Overall, and as far as I understand, for your implementation here https://github.com/huggingface/datasets/blob/master/metrics/rouge/rouge.py#L65 to match the default, you only need to change `rougeL` [here](https://github.com/huggingface/datasets/blob/master/metrics/rouge/rouge.py#L86) to `rougeLsum` to correctly compute metrics for text with newlines.
Tagging @sshleifer who might be interested. | I used RougeL implementation provided in `datasets` [here](https://github.com/huggingface/datasets/blob/master/metrics/rouge/rouge.py) and it gives numbers that match those reported in the pegasus paper but very different from those reported in other papers, [this](https://arxiv.org/pdf/1909.03186.pdf) for example.
Can you make sure the google-research implementation you are using matches the official perl implementation?
There are a couple of python wrappers around the perl implementation, [this](https://pypi.org/project/pyrouge/) has been commonly used, and [this](https://github.com/pltrdy/files2rouge) is used in fairseq).
There's also a python reimplementation [here](https://github.com/pltrdy/rouge) but its RougeL numbers are way off.

We implemented a more involved [solution](https://github.com/huggingface/transformers/blob/99cb924bfb6c4092bed9232bea3c242e27c6911f/examples/seq2seq/utils.py#L481) that enforces that sentences are split with `\n` so that rougeLsum scores match papers even if models don't generate newlines.

#### Sidebar: Wouldn't Deterministic Be Better?
`rouge_scorer.scoring.BootstrapAggregator` is well named but is not deterministic which I would like to change for my mental health, unless there is some really good reason to sample 500 observations before computing f-scores.
I have a fix on a branch, but I wanted to get some context before introducting a 4th way to compute rouge. Scores are generally within .03 Rouge2 of boostrap after multiplying by 100, e.g 22.05 vs 22.08 Rouge2.

That's exactly the argument in my first sentence. Too often someone "cannot think of a use-case", but you can not foresee the use-cases of a whole research community.

That's fair.
> Plain use cases should really not generate warnings. It teaches developers to ignore warnings which is a terrible practice.
But this is not a plain use-case (because Pytorch does not support these read-only tensors). Manually setting the flag to writable will solve the issue on the surface but is basically just a hack to compensate for something that is not allowed in another library.
What about an "ignore_warnings" flag in `set_format` that when True wraps the offending code in a block to ignore userwarnings at that specific step in [_convert_outputs](https://github.com/huggingface/datasets/blob/880c2c76a8223a00c303eab2909371e857113063/src/datasets/arrow_dataset.py#L821)? Something like:
```python
def _convert_outputs(..., ignore_warnings=True):
...
with warnings.catch_warnings():
if ignore_warnings:
warnings.simplefilter("ignore", UserWarning)
return torch.tensor(...)
# continues without warning filter after context manager...

> The right argument here is that if code depends on `.flags.writable` being truthful (not just for warnings), then it will cause unavoidable errors. Although, I can't imagine such a use-case.
That's exactly the argument in my first sentence. Too often someone "cannot think of a use-case", but you can not foresee the use-cases of a whole research community.
> I don't want to ignore all `UserWarnings`, nor all warnings regarding non-writable arrays. Ignoring warnings leads to hard to debug issues.
That's fair.
> Plain use cases should really not generate warnings. It teaches developers to ignore warnings which is a terrible practice.
But this is not a plain use-case (because Pytorch does not support these read-only tensors). Manually setting the flag to writable will solve the issue on the surface but is basically just a hack to compensate for something that is not allowed in another library.
What about an "ignore_warnings" flag in `set_format` that when True wraps the offending code in a block to ignore userwarnings at that specific step in [_convert_outputs](https://github.com/huggingface/datasets/blob/880c2c76a8223a00c303eab2909371e857113063/src/datasets/arrow_dataset.py#L821)? Something like:
```python
def _convert_outputs(..., ignore_warnings=True):
...
with warnings.catch_warnings():
if ignore_warnings:
warnings.simplefilter("ignore", UserWarning)
return torch.tensor(...)
# continues without warning filter after context manager...

It's definitely a size thing. I took a smaller dataset with 87000 rows and did:
```
for i in range(10,1000,20):
table = pa.concat_tables([dset._data]*i)

and it broke at around i=300.
Also when `_indices` is not None, this breaks indexing by slice. E.g. `dset.shuffle()[:1]` breaks.
Luckily so far I haven't seen `_indices.column(0).take` break, which means it doesn't break `select` or anything like that which is where the speed really matters, it's just `_getitem`. So I'm currently working around it by just doing the arrow v0 method in `_getitem`:

ArrowInvalid: offset overflow while concatenating arrays
```
It seems to work fine with small datasets or with pyarrow 0.17.1
Facing the same issue.
Steps to reproduce: (dataset is a few GB big so try in colab maybe)
Datasets version - 2.11.0
```
import datasets
import re
ds = datasets.load_dataset('nishanthc/dnd_map_dataset_v0.1', split = 'train')
def get_text_caption(example):
regex_pattern = r'\s\d+x\d+|,\sLQ|,\sgrid|\.\w+$'
example['text_caption'] = re.sub(regex_pattern, '', example['picture_text'])
return example
ds = ds.map(get_text_caption)
```
I am trying to apply a regex to remove certain patterns from a text column. Not sure why this error is showing up. |

https://github.com/huggingface/datasets/issues/611 | ArrowCapacityError: List array cannot contain more than 2147483646 child elements, have 2147483648 | It looks like a Pyarrow limitation.
I was able to reproduce the error with
```python
import pandas as pd
import numpy as np
import pyarrow as pa
n = 1713614
df = pd.DataFrame.from_dict({"a": list(np.zeros((n, 128))), "b": range(n)})
pa.Table.from_pandas(df)
```
I also tried with 50% of the dataframe and it actually works.
I created an issue on Apache Arrow's JIRA [here](https://issues.apache.org/jira/browse/ARROW-9976)
One way to fix that would be to chunk the dataframe and concatenate arrow tables. | Hi, I'm trying to load a dataset from Dataframe, but I get the error:

I was able to reproduce the error with
```python

n = 1713614
df = pd.DataFrame.from_dict({"a": list(np.zeros((n, 128))), "b": range(n)})
pa.Table.from_pandas(df)
```
I also tried with 50% of the dataframe and it actually works.
I created an issue on Apache Arrow's JIRA [here](https://issues.apache.org/jira/browse/ARROW-9976)
One way to fix that would be to chunk the dataframe and concatenate arrow tables. |

Thanks for your suggestion.
I tried
```
dataset = load_dataset('text', data_files='test.txt',cache_dir="./", split="train")
print(dataset)
dataset.set_format(type='torch',columns=["text"])
dataloader = torch.utils.data.DataLoader(dataset, batch_size=8)
next(iter(dataloader))
```
But it still doesn't work and got error:
```

I found type can be ['numpy', 'torch', 'tensorflow', 'pandas'] only, how can I deal with the string type? |

https://github.com/huggingface/datasets/issues/610 | Load text file for RoBERTa pre-training. | Hey @chiyuzhang94, I was also having trouble in loading a large text file (11GB).
But finally got it working. This is what I did after looking into the documentation.
1. split the whole dataset file into smaller files
```bash
mkdir ./shards
split -a 4 -l 256000 -d full_raw_corpus.txt ./shards/shard_
````
2. Pass paths of small data files to `load_dataset`
```python
files = glob.glob('shards/*')
from datasets import load_dataset
dataset = load_dataset('text', data_files=files, split='train')
```
(On passing the whole dataset file (11GB) directly to `load_dataset` was resulting into RAM issue)
3. Tokenization
```python
def encode(examples):
return tokenizer(examples['text'], truncation=True, padding='max_length')
dataset = dataset.map(encode, batched=True)
dataset.set_format(type='torch', columns=['input_ids', 'attention_mask'])
```
Now you can pass `dataset` to `Trainer` or `pytorch DataLoader`
```python
dataloader = torch.utils.data.DataLoader(dataset, batch_size=4)
next(iter(dataloader))
```
Hope this helps

Thanks, @thomwolf and @sipah00 ,
I tried to implement your suggestions in my scripts.
Now, I am facing some connection time-out error. I am using my local file, I have no idea why the module request s3 database.
The log is:

I tried to train a Roberta from scratch using transformers. But I got OOM issues with loading a large text file.
According to the suggestion from @thomwolf , I tried to implement `datasets` to load my text file. This test.txt is a simple sample where each line is a sentence.
```
from datasets import load_dataset
dataset = load_dataset('text', data_files='test.txt',cache_dir="./")
dataset.set_format(type='torch',columns=["text"])
dataloader = torch.utils.data.DataLoader(dataset, batch_size=8)
next(iter(dataloader))
```
But dataload cannot yield sample and error is:

I am also struggling with this adaptation.
I am not sure whether I am right.
I think you don't need to construct `class LazyLineByLineTextDataset(Dataset)` at all.
torch.utils.data.Dataset is a generator.
Now, we use `dataset = dataset.map(encode, batched=True)` as a generator. So we just pass dataset to torch.utils.data.DataLoader. | I migrate my question from https://github.com/huggingface/transformers/pull/4009#issuecomment-690039444

I noticed the dataset is `DatasetDict({'train': Dataset(features: {'text': Value(dtype='string', id=None)}, num_rows: 44)})`.
Each sample can be accessed by `dataset["train"]["text"]` instead of `dataset["text"]`.
Could you please give me any suggestions on how to modify this code to load the text file?

I am also struggling with this adaptation.
I am not sure whether I am right.
I think you don't need to construct `class LazyLineByLineTextDataset(Dataset)` at all.
torch.utils.data.Dataset is a generator.
Now, we use `dataset = dataset.map(encode, batched=True)` as a generator. So we just pass dataset to torch.utils.data.DataLoader. |

I tried to train a Roberta from scratch using transformers. But I got OOM issues with loading a large text file.
According to the suggestion from @thomwolf , I tried to implement `datasets` to load my text file. This test.txt is a simple sample where each line is a sentence.
```

dataset.set_format(type='torch',columns=["text"])
dataloader = torch.utils.data.DataLoader(dataset, batch_size=8)

I migrate my question from https://github.com/huggingface/transformers/pull/4009#issuecomment-690039444
I tried to train a Roberta from scratch using transformers. But I got OOM issues with loading a large text file.
According to the suggestion from @thomwolf , I tried to implement `datasets` to load my text file. This test.txt is a simple sample where each line is a sentence.
```
from datasets import load_dataset
dataset = load_dataset('text', data_files='test.txt',cache_dir="./")
dataset.set_format(type='torch',columns=["text"])
dataloader = torch.utils.data.DataLoader(dataset, batch_size=8)
next(iter(dataloader))
```
But dataload cannot yield sample and error is:
```

https://github.com/huggingface/datasets/issues/610 | Load text file for RoBERTa pre-training. | Hi @thomwolf , @lhoestq ,
Thanks for your suggestions. With the latest version of this package, I can load text data without Internet.
But I found the speed of dataset loading is very slow.
My scrips like this:
```
def token_encode(examples):
tokenizer_out = tokenizer(examples['text'], truncation=True, padding="max_length", add_special_tokens=True, max_length=args.block_size)
return tokenizer_out
path = Path(file_path)
files = sorted(path.glob('*'))
dataset = load_dataset('./text.py', data_files=files, cache_dir = args.data_cache_dir, split="train")
dataset = dataset.map(token_encode, batched=True)
dataset.set_format(type='torch', columns=['input_ids', 'attention_mask'])
```
I have 1,123,870,657 lines in my input directory.
I can find the processing speed as following. It is very slow.
```

Hi @lhoestq ,
Thanks. I will try it.
You are right. I have 1,123,870,657 lines totally in the path. I split the large file into 440 small files. Each file has 2,560,000 lines.
I have another question. Because I am using a cloud server where only allows running a job up to 7 days. Hence, I need to resume my model every week. If the script needs to load and process the dataset every time. It is very low efficient based on the current processing speed. Is it possible that I process the dataset once and use the process cache to in the future work?

If the script needs to load and process the dataset every time. It is very low efficient based on the current processing speed. Is it possible that I process the dataset once and use the process cache to in the future work?
