# InstructBLIP model
|
| 11 |
+
|
| 12 |
+
InstructBLIP model using [Vicuna-7b](https://github.com/lm-sys/FastChat#model-weights) as language model. InstructBLIP was introduced in the paper [InstructBLIP: Towards General-purpose Vision-Language Models with Instruction Tuning](https://arxiv.org/abs/2305.06500) by Dai et al.
|
| 13 |
+
|
| 14 |
+
Disclaimer: The team releasing InstructBLIP did not write a model card for this model so this model card has been written by the Hugging Face team.
|
| 15 |
+
|
| 16 |
+
## Model description
|
| 17 |
+
|
| 18 |
+
InstructBLIP is a visual instruction tuned version of [BLIP-2](https://huggingface.co/docs/transformers/main/model_doc/blip-2). Refer to the paper for details.

+
## Intended uses & limitations
|
| 23 |
+
|
| 24 |
+
Usage is as follows:
|
| 25 |
+
|
| 26 |
+
```
|
| 27 |
+
from transformers import InstructBlipProcessor, InstructBlipForConditionalGeneration
|
| 28 |
+
import torch
|
| 29 |
+
from PIL import Image
|
| 30 |
+
import requests
|
| 31 |
+
|
| 32 |
+
model = InstructBlipForConditionalGeneration.from_pretrained("Salesforce/instructblip-vicuna-7b")
|
| 33 |
+
processor = InstructBlipProcessor.from_pretrained("Salesforce/instructblip-vicuna-7b")
|
| 34 |
+
|
| 35 |
+
device = "cuda" if torch.cuda.is_available() else "cpu"
|
| 36 |
+
model.to(device)
|
| 37 |
+
|
| 38 |
+
url = "https://raw.githubusercontent.com/salesforce/LAVIS/main/docs/_static/Confusing-Pictures.jpg"
|
| 39 |
+
image = Image.open(requests.get(url, stream=True).raw).convert("RGB")
|
| 40 |
+
prompt = "What is unusual about this image?"
|
| 41 |
+
inputs = processor(images=image, text=prompt, return_tensors="pt")
|
| 42 |
+
|
| 43 |
+
outputs = model.generate(
|
| 44 |
+
**inputs,
|
| 45 |
+
do_sample=False,
|
| 46 |
+
num_beams=1,
|
| 47 |
+
max_length=256,
|
| 48 |
+
min_length=1,
|
| 49 |
+
top_p=0.9,
|
| 50 |
+
repetition_penalty=1.5,
|
| 51 |
+
length_penalty=1.0,
|
| 52 |
+
temperature=1,
|
| 53 |
+
)
|
| 54 |
+
generated_text = processor.batch_decode(outputs, skip_special_tokens=True)[0].strip()
|
| 55 |
+
print(generated_text)
|
| 56 |
+
```
|
| 57 |
+
|
| 58 |
+
Note that this shows unconditional generation of text given an image. You can also make the model continue a text prompt.
