## Sharded BLIP-2 Model Card - flan-t5-xl
<a href="https://colab.research.google.com/gist/pszemraj/0822b7f28b14405f10cfd382296873de/blip2-flan-t5-xl-sharded-example.ipynb">

</a>
This is a sharded version of the [blip2-flan-t5-xl](https://huggingface.co/Salesforce/blip2-flan-t5-xl) which leverages [Flan T5-xl](https://huggingface.co/google/flan-t5-xl) for image-to-text tasks such as image captioning and visual question answering.
- this model repo is sharded so it can be easily loaded on low-RAM Colab runtimes :)
- Refer to the [original model card](https://huggingface.co/Salesforce/blip2-flan-t5-xl) for more details about the model description, intended uses, and limitations, as well as instructions for how to use the model on CPU and GPU in different precisions.
## Usage
Refer to the original model card for details or see [this blog post](https://huggingface.co/blog/blip-2#using-blip-2-with-hugging-face-transformers). Here is how you can use it on CPU:
Install
Requires the current `main` of transformers (_at time of writing_):
```bash
pip install accelerate git+https://github.com/huggingface/transformers.git -U -q
```
Use (_this is for CPU, check out the original model card/blog for `fp16` and `int8` usage_)
```python
import requests
from PIL import Image
from transformers import BlipProcessor, Blip2ForConditionalGeneration
model_name = "ethzanalytics/blip2-flan-t5-xl-sharded"
processor = BlipProcessor.from_pretrained(model_name)
model = Blip2ForConditionalGeneration.from_pretrained(model_name)
img_url = 'https://storage.googleapis.com/sfr-vision-language-research/BLIP/demo.jpg'
raw_image = Image.open(requests.get(img_url, stream=True).raw).convert('RGB')
question = "how many dogs are in the picture?"
inputs = processor(raw_image, question, return_tensors="pt")
out = model.generate(**inputs)
print(processor.decode(out[0], skip_special_tokens=True))
