Prepare dataset

Preprocess training data from json files

  1. Download the json files from the link provided in the ALBEF repo - https://storage.googleapis.com/sfr-pcl-data-research/ALBEF/json_pretrain.zip

  2. Go to line number 29 in src/scripts/json_preprocess.py and provide paths to the json files downloaded in step 1.

  3. Run the following command. This will create a csv file json_data.csv and puts it in the folder named csvs.

python src/scripts/json_preprocess.py

Preprocess training and validation for COCO

The following commands will create csv files csvs/val_coco.csv and csvs/train_coco.csv which we will use for training and validation.

python src/scripts/coco_preprocess.py --split train --data-root /path/to/coco/dataset/
python src/scripts/coco_preprocess.py --split val --data-root /path/to/coco/dataset/

Start training:

python -u src/training/main.py \
    --train-data="/path/to/json_data.csv"  \
    --val-data="/path/to/val_coco.csv"  \
    --warmup 10000 \
    --batch-size=128 \
    --lr=5e-4 \
    --wd=0.1 \
    --epochs=30 \
    --workers=4 \
    --model RN50
