## Summary |
|
|
|
This is the model card of a 🤗 transformers model that has been pushed on the Hub. |
|
Previous vision models have been 50/50 as the multimodel model actully requires a lot of memory and gpu and harddrive space to create; |
|
the past versions have been attempts to Merge the capabilitys into the main mistral model whilst still retaining its mistral tag! |
|
After reading many hugging face articles: |
|
|
|
The BackBone Issue is the main cause of creating multi modals !: |
|
|
|
with the advent of tiny models we are able to leverage the decoder abilitys as a single expert-ish... within the model : |
|
by reducing the size to a fully trainined tiny model! |
|
this will only produce decodings and not conversations so it needs to be smart and respond with defined answers: but in general it will produce captions: but as domain based it may be specialized in medical or art etc: |
|
|
|
The main llm still needs to retain these models within hence the back bone method of instigating a VisionEncoderDecoder model: istead of a llava model which still need wrangling to work correctly without spoiling the original transformers installation: |
|
Previous experiments proved that the mistral large model could be used as a decoder but the total model jumped to 13b so the when applying the tiny model it was only effected by the weight of the model 248M |

|
## How to Get Started with the Model |
|
|
|
|
|
### VisionEncoderDecoderModel |
|
#### As a vision encoder model : |
|
|
|
the tensors are combined into the original mistral model so it can be accessed by intaciating the correct model which is the VisionEncoderDecoderModel |
|
|
|
|
|
```python |
|
from transformers import AutoProcessor, VisionEncoderDecoderModel |
|
import requests |
|
from PIL import Image |
|
import torch |
|
|
|
processor = AutoProcessor.from_pretrained("LeroyDyer/Mixtral_AI_Cyber_Q_Vision") |
|
model = VisionEncoderDecoderModel.from_pretrained("LeroyDyer/Mixtral_AI_Cyber_Q_Vision") |
|
|
|
# load image from the IAM dataset |
|
url = "https://fki.tic.heia-fr.ch/static/img/a01-122-02.jpg" |
|
image = Image.open(requests.get(url, stream=True).raw).convert("RGB") |
|
|
|
# training |
|
model.config.decoder_start_token_id = processor.tokenizer.eos_token_id |
|
model.config.pad_token_id = processor.tokenizer.pad_token_id |
|
model.config.vocab_size = model.config.decoder.vocab_size |
|
|
|
pixel_values = processor(image, return_tensors="pt").pixel_values |
|
text = "hello world" |
|
labels = processor.tokenizer(text, return_tensors="pt").input_ids |
|
outputs = model(pixel_values=pixel_values, labels=labels) |
|
loss = outputs.loss |
|
|
|
# inference (generation) |
|
generated_ids = model.generate(pixel_values) |
|
generated_text = processor.batch_decode(generated_ids, skip_special_tokens=True)[0] |
|
``` |
|
### As a standard LLM: |
|
|
|
it can still also be used as a normal AutoModelForCausalLM or MistralModelForCausalLM ! |
|
|
|
[More Information Needed] |
|
|
|
## Training Details |
|
|
|
Currently inputs are raw and untrained ; |
|
|
|
ie: they NEED to be trained as the tensors are randomize maybe? |
|
despite using pretrained starting blocks. the encoder decoder modules are ready to be placed in train mode: |
|
The main model ie the LLM will need lora/Qlora/Peft etc: |
|
|
|
This model will stay in this state as a base training point ! so later versions will be trained; |
|
This model is fully usable and still expected to score well ; |
|
|
|
The small tiny mistral is also a great performer and a great block to begin a smaller experts model (later) or any multimodal project ie: its like a mini pretrined bert/llama(Mistral is a clone of llamaAlpaca! |
|
|
|
```python |
|
|
|
|
|
from transformers import ViTImageProcessor, AutoTokenizer, VisionEncoderDecoderModel |
|
from datasets import load_dataset |
|
|
|
image_processor = ViTImageProcessor.from_pretrained("LeroyDyer/Mixtral_AI_Cyber_Q_Vision") |
|
tokenizer = AutoTokenizer.from_pretrained("LeroyDyer/Mixtral_AI_Cyber_Q_Vision") |
|
model = VisionEncoderDecoderModel.from_encoder_decoder_pretrained( |
|
"LeroyDyer/Mixtral_AI_Cyber_Q_Vision", "LeroyDyer/Mixtral_AI_Cyber_Q_Vision" |
|
) |
|
|
|
model.config.decoder_start_token_id = tokenizer.cls_token_id |
|
model.config.pad_token_id = tokenizer.pad_token_id |
|
|
|
dataset = load_dataset("huggingface/cats-image") |
|
image = dataset["test"]["image"][0] |
|
pixel_values = image_processor(image, return_tensors="pt").pixel_values |
|
|
|
labels = tokenizer( |
|
"an image of two cats chilling on a couch", |
|
return_tensors="pt", |
|
).input_ids |
|
|
|
# the forward function automatically creates the correct decoder_input_ids |
|
loss = model(pixel_values=pixel_values, labels=labels).loss |
|
|
|
|
|
|
|
``` |
|
|
|
|
|
### Model Architecture |
|
|
|
|
|
Aha !!! Here is how you create such a model :: |
|
|
|
|
|
|
|
``` python |
|
|
|
from transformers import MistralConfig, ViTConfig, VisionEncoderDecoderConfig, VisionEncoderDecoderModel |
|
|
|
# Initializing a ViT & Mistral style configuration |
|
config_encoder = ViTConfig() |
|
config_decoder = MistralConfig() |
|
|
|
config = VisionEncoderDecoderConfig.from_encoder_decoder_configs(config_encoder, config_decoder) |
|
|
|
# Initializing a ViTMistral model (with random weights) from a ViT & Mistral style configurations |
|
model = VisionEncoderDecoderModel(config=config) |
|
|
|
# Accessing the model configuration |
|
config_encoder = model.config.encoder |
|
config_decoder = model.config.decoder |
|
# set decoder config to causal lm |
|
config_decoder.is_decoder = True |
|
config_decoder.add_cross_attention = True |
|
|
|
# Saving the model, including its configuration |
|
model.save_pretrained("my-model") |
|
|
|
# loading model and config from pretrained folder |
|
encoder_decoder_config = VisionEncoderDecoderConfig.from_pretrained("my-model") |
|
model = VisionEncoderDecoderModel.from_pretrained("my-model", config=encoder_decoder_config) |
|
|
|
|
|
``` |
