Improved Probabilistic Image-Text Representations (PCME++) (ICLR 2024)
Official Python implementation of PCME++ | Paper | Project page
This codebase is built upon the following repositories
- https://github.com/woodfrog/vse_infty
- https://github.com/naver-ai/pcme
- https://github.com/openai/CLIP
Updates
- 08 Apr, 2024: HuggingFace model for ImageNet zero-shot is released. See hf_example.py for more details
- 07 Aug, 2023: Code is released!
Installation
Please check the library version before you run the code:
lightning==2.0.1
torch==2.0
torchtext==0.15.1
torchvision==0.15.1
transformers
Or, simply run pip install (I strongly recommend making a new virtual environment before you run this):
pip3 install -r requirements.txt
Dataset preparation
Step 1. Download COCO 2014 images from the official website: https://cocodataset.org/#download I may assume that your dataset file directory looks like
/path/to/dataset
└── images
├── train2014 # approximately 82k images are here
└── val2014 # approximately 40k images are here
Step 2. Download annotation files from this link and untar the annotations to the dataset path. It will make your dataset file directory will be
/path/to/dataset
└── images
└── ...
├── id_mapping.json # mapping file for image and captions
├── cxc_annots # annotations for CxC evaluation of VSE infty codebase
└── precomp # caption annotations are here
├── train_caps.txt
├── train_ids.txt
├── dev_caps.txt
├── dev_ids.txt
├── test_caps.txt
├── test_ids.txt
├── testall_caps.txt
└── testall_ids.txt
Quick start
- Most of the experiments are reproducible with a single V100. If you want to use multiple GPUs (e.g., larger batch size, or larger model), you should specify
--train__dist_train
option. - If you would like to run multiple experiments using this repository, it would be better to specify your
expname
usingtrain__expname
. The defaultexpname
isresults
, and all logs and weights will be dumped toresults
, ifexpname
is not specified.
You can reproduce the main results by the following commands:
# PCME++ ViT-B/32 backbone
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/pcmepp.yaml --dataloader__data_path /path/to/dataset
# PCME++ ViT-B/16 backbone
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/pcmepp.yaml --dataloader__data_path /path/to/dataset --model__backbone_source clip_ViT-B/16
# PCME++ ViT-L/14 backbone
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3 train.py ./configs/pcmepp.yaml --dataloader__data_path /path/to/dataset --model__backbone_source clip_ViT-L/14 --model__img_dim 1024 --dataloader__batch_size 16 --train__dist_train
This repository also provides noise ratio
option as follows:
# PCME++ ViT-B/32 backbone with noise ratio 20%
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/pcmepp.yaml --dataloader__data_path /path/to/dataset --dataloader__noise_ratio 0.2
# PCME++ ViT-B/32 backbone with noise ratio 50%
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/pcmepp.yaml --dataloader__data_path /path/to/dataset --dataloader__noise_ratio 0.5
You can train the baselines methods using the following commands:
# ViT-B/32 backbones. Changing backbone is the same as the PCME++ backbone changes
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/others/vse_infty.yaml --dataloader__data_path /path/to/dataset
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/others/info_nce.yaml --dataloader__data_path /path/to/dataset
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/others/pcmepp_mu_only.yaml --dataloader__data_path /path/to/dataset
CUDA_VISIBLE_DEVICES=0 python3 train.py ./configs/others/pcme.yaml --dataloader__data_path /path/to/dataset
# only exception is InfoNCE + multiple GPUs
CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3 train.py ./configs/others/info_nce.yaml --dataloader__data_path /path/to/dataset --model__backbone_source clip_ViT-L/14 --model__img_dim 1024 --dataloader__batch_size 16 --train__dist_train --train__all_gather_infonce
Official weights
We will provide the official weights for each model in the paper.
