## BLIP: Bootstrapping Language-Image Pre-training for Unified Vision-Language Understanding and Generation



## Announcement: BLIP is now officially integrated into [LAVIS](https://github.com/salesforce/LAVIS) - a one-stop library for language-and-vision research and applications!






This is the PyTorch code of the BLIP paper [[blog](https://blog.salesforceairesearch.com/blip-bootstrapping-language-image-pretraining/)]. The code has been tested on PyTorch 1.10.

To install the dependencies, run 
pip install -r requirements.txt

### Inference demo:

Run our interactive demo using [Colab notebook](https://colab.research.google.com/github/salesforce/BLIP/blob/main/demo.ipynb) (no GPU needed).

The demo includes code for: 

1. Image captioning

2. Open-ended visual question answering

3. Multimodal / unimodal feature extraction

4. Image-text matching



Try out the [Web demo](https://huggingface.co/spaces/Salesforce/BLIP), integrated into [Huggingface Spaces 🤗](https://huggingface.co/spaces) using [Gradio](https://github.com/gradio-app/gradio). 



Replicate web demo and Docker image is also available at [![Replicate](https://replicate.com/salesforce/blip/badge)](https://replicate.com/salesforce/blip)

### Image-Text Retrieval:

1. Download COCO and Flickr30k datasets from the original websites, and set 'image_root' in configs/retrieval_{dataset}.yaml accordingly.

2. To evaluate the finetuned BLIP model on COCO, run:

python -m torch.distributed.run --nproc_per_node=8 train_retrieval.py \

--config ./configs/retrieval_coco.yaml \

--output_dir output/retrieval_coco \

--evaluate
 

3. To finetune the pre-trained checkpoint using 8 A100 GPUs, first set 'pretrained' in configs/retrieval_coco.yaml as "https://storage.googleapis.com/sfr-vision-language-research/BLIP/models/model_base.pth". Then run:

python -m torch.distributed.run --nproc_per_node=8 train_retrieval.py \

--config ./configs/retrieval_coco.yaml \

--output_dir output/retrieval_coco 
 



### Image-Text Captioning:

1. Download COCO and NoCaps datasets from the original websites, and set 'image_root' in configs/caption_coco.yaml and configs/nocaps.yaml accordingly.

2. To evaluate the finetuned BLIP model on COCO, run:

python -m torch.distributed.run --nproc_per_node=8 train_caption.py --evaluate
 

3. To evaluate the finetuned BLIP model on NoCaps, generate results with: (evaluation needs to be performed on official server)

python -m torch.distributed.run --nproc_per_node=8 eval_nocaps.py 
 

4. To finetune the pre-trained checkpoint using 8 A100 GPUs, first set 'pretrained' in configs/caption_coco.yaml as "https://storage.googleapis.com/sfr-vision-language-research/BLIP/models/model_base_capfilt_large.pth". Then run:

python -m torch.distributed.run --nproc_per_node=8 train_caption.py 
 



### VQA:

1. Download VQA v2 dataset and Visual Genome dataset from the original websites, and set 'vqa_root' and 'vg_root' in configs/vqa.yaml.

2. To evaluate the finetuned BLIP model, generate results with: (evaluation needs to be performed on official server)

python -m torch.distributed.run --nproc_per_node=8 train_vqa.py --evaluate
 

3. To finetune the pre-trained checkpoint using 16 A100 GPUs, first set 'pretrained' in configs/vqa.yaml as "https://storage.googleapis.com/sfr-vision-language-research/BLIP/models/model_base_capfilt_large.pth". Then run:

python -m torch.distributed.run --nproc_per_node=16 train_vqa.py 
 



### NLVR2:

1. Download NLVR2 dataset from the original websites, and set 'image_root' in configs/nlvr.yaml.

2. To evaluate the finetuned BLIP model, run

python -m torch.distributed.run --nproc_per_node=8 train_nlvr.py --evaluate
 

3. To finetune the pre-trained checkpoint using 16 A100 GPUs, first set 'pretrained' in configs/nlvr.yaml as "https://storage.googleapis.com/sfr-vision-language-research/BLIP/models/model_base.pth". Then run:

python -m torch.distributed.run --nproc_per_node=16 train_nlvr.py 
 



### Finetune with ViT-L:

In order to finetune a model with ViT-L, simply change the config file to set 'vit' as large. Batch size and learning rate may also need to be adjusted accordingly (please see the paper's appendix for hyper-parameter details). Gradient checkpoint can also be activated in the config file to reduce GPU memory usage. 



### Pre-train:

1. Prepare training json files where each json file contains a list. Each item in the list is a dictonary with two key-value pairs: {'image': path_of_image, 'caption': text_of_image}. 

2. In configs/pretrain.yaml, set 'train_file' as the paths for the json files .

3. Pre-train the model using 8 A100 GPUs:

python -m torch.distributed.run --nproc_per_node=8 pretrain.py --config ./configs/Pretrain.yaml --output_dir output/Pretrain 
 



### Zero-shot video-text retrieval:

1. Download MSRVTT dataset following the instructions from https://github.com/salesforce/ALPRO, and set 'video_root' accordingly in configs/retrieval_msrvtt.yaml.

2. Install [decord](https://github.com/dmlc/decord) with 
pip install decord
 

3. To perform zero-shot evaluation, run

python -m torch.distributed.run --nproc_per_node=8 eval_retrieval_video.py
 



### Pre-training datasets download:

We provide bootstrapped pre-training datasets as json files. Each json file contains a list. Each item in the list is a dictonary with two key-value pairs: {'url': url_of_image, 'caption': text_of_image}.
