# Dataset

Japanese subset of the [mC4](https://huggingface.co/datasets/mc4) dataset

# Training

Trained for 3000 steps on top of the MPT 7b checkpoint [mosaicml/mpt-7b](https://huggingface.co/mosaicml/mpt-7b)

# How to load

Before running this model, please install the following pip package:

```bash
pip install einops
```

To load the model, run the following command.

```python
from transformers import AutoModelForCausalLM

model_name = "lightblue/japanese-mpt-7b"
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype='auto',
    trust_remote_code=True
)
```

To run this model, you may need to load it in a lower precision in order for it to fit onto your GPU. We found for a T4 GPU, it requires loading the model in 8-bit precision. To load the model in 8-bit and 4-bit, please install the following pip packages:

```bash
pip install bitsandbytes accelerate
```

Caution - you will also need enough RAM to load the model. We estimate loading this model requires ~30GB.

# How to use
```python
from transformers import AutoTokenizer, pipeline

tokenizer = AutoTokenizer.from_pretrained(model_name, trust_remote_code=True)

pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)

prompt = """A: こんにちは
B: こんにちは
A: 好きなスポーツは何ですか？
B: サッカーです
A: 好きな食べ物は何ですか？
B:"""

pipe(prompt, temperature=0, do_sample=False, return_full_text=False, max_new_tokens=32)
# [{"generated_text": " カレーです
# A: 好きな色は何ですか？
# B: 赤です"}]
