Scale Up Composed Image Retrieval Learning via Modification Text Generation

Prerequisites (Following SPRC)

The following commands will create a local Anaconda environment with the necessary packages installed.

conda create -n mtst -y python=3.9
conda activate mtst
pip install torch==2.0.1 torchvision==0.15.2 torchaudio==2.0.2
pip install -r requirements.txt

Data Preparation (Following SPRC)

To properly work with the codebase FashionIQ and CIRR datasets should have the following structure:

project_base_path
└───  fashionIQ_dataset
      └─── captions
            | cap.dress.test.json
            | cap.dress.train.json
            | cap.dress.val.json
            | ...
            
      └───  images
            | B00006M009.jpg
            | B00006M00B.jpg
            | B00006M6IH.jpg
            | ...
            
      └─── image_splits
            | split.dress.test.json
            | split.dress.train.json
            | split.dress.val.json
            | ...

change ``base_path = Path("path_to_data_dir")'' in MTST_PTHA/src/data_utils.py Download pretrained path from "https://huggingface.co/yinanzhou1/mtst_ptha/blob/main/tuned_mtst_cirr.pt" Download generated pretraining data from "https://huggingface.co/yinanzhou1/mtst_ptha/blob/main/cirr_modifier_generated_5p_completed_rev.json" Download generated finetuning data from "https://huggingface.co/yinanzhou1/mtst_ptha/blob/main/cirr_train_modifier_rev_long.json"

Pre-Training

python src/blip_fine_tune_2.py \
   --dataset {'CIRRGen' or 'FashionIQGen'} \
   --blip-model-name 'blip2_cir_cat' \
   --num-epochs {'10' for CIRR, '30' for fashionIQ} \
   --num-workers 4 \
   --learning-rate {'1e-5' for CIRR, '2e-5' for fashionIQ} \
   --batch-size 128 \
   --transform targetpad \
   --target-ratio 1.25  \
   --save-training \
   --save-best \
   --validation-frequency 1

Training

change the path of ``pretrained: "PATH_TO_PRETRAINED_WEIGHTS" '' in MTST_PTHA/src/lavis/configs/models/blip2/blip2_pretrain_mtst.yaml for finetuning MTST pretrained model

python src/blip_fine_tune_2.py \
   --dataset {'CIRR' or 'FashionIQ'} \
   --blip-model-name 'blip2_tgir_ce_sim' \
   --num-epochs {'50' for CIRR, '30' for fashionIQ} \
   --num-workers 4 \
   --learning-rate {'5e-6' for CIRR, '1e-5' for fashionIQ} \
   --batch-size 128 \
   --transform targetpad \
   --target-ratio 1.25  \
   --save-training \
   --save-best \
   --validation-frequency 1 
   --backbone {"pretrain_mtst" for pretrained model using mtst, "pretrain" for initialized model from blip-2}

Evaluation

python src/blip_validate.py \
   --dataset {'CIRR' or 'FashionIQ'} \
   --blip-model-name {trained model name} \
   --model-path {for path}

CIRR Testing

python src/cirr_test_submission.py \
   --blip-model-name {trained model name} \
   --model-path {for path}
