Fine-tuning BEiT-3 on Image-text Retrieval

COCO Retrieval Setup

Setup environment.
Download 2014 train images, 2014 val images and karpathy split, then organize the dataset as following structure:

/path/to/your_data/
  train2014/            
    COCO_train2014_000000000009.jpg                
    ...
  val2014/              
    COCO_val2014_000000000042.jpg
    ...       
  dataset_coco.json

We then generate the index json files using the following command. beit3.spm is the sentencepiece model used for tokenizing texts.

from datasets import RetrievalDataset
from transformers import XLMRobertaTokenizer

tokenizer = XLMRobertaTokenizer("/your_beit3_model_path/beit3.spm")

RetrievalDataset.make_coco_dataset_index(
    data_path="/path/to/your_data",
    tokenizer=tokenizer,
)

Flickr30k Retrieval Setup

Setup environment.
Sign flickr images request form and download karpathy split, then organize the dataset as following structure:

/path/to/your_data/
  flickr30k-images/            
    2923475135.jpg                
    ...      
  dataset_flickr30k.json

We then generate the index json files using the following command. beit3.spm is the sentencepiece model used for tokenizing texts.

from datasets import RetrievalDataset
from transformers import XLMRobertaTokenizer

tokenizer = XLMRobertaTokenizer("/your_beit3_model_path/beit3.spm")

RetrievalDataset.make_flickr30k_dataset_index(
    data_path="/path/to/your_data",
    tokenizer=tokenizer,
    karpathy_path="/path/to/your_data",
)

Example: Fine-tuning BEiT-3 on Retrieval

The BEiT-3 base model can be finetuned on retrieval tasks using 16 V100-32GB:

bash

python -m torch.distributed.launch --nproc_per_node=16 run_beit3_finetuning.py \
        --model beit3_base_patch16_384 \
        --input_size 384 \
        --task coco_retrieval \
        --batch_size 192 \
        --layer_decay 0.65 \
        --lr 2e-4 \
        --epochs 15 \
        --warmup_epochs 3 \
        --drop_path 0.2 \
        --sentencepiece_model /your_beit3_model_path/beit3.spm \
        --finetune /your_beit3_model_path/beit3_base_itc_patch16_224.pth \
        --data_path /path/to/your_data \
        --output_dir /path/to/save/your_model \
        --log_dir /path/to/save/your_model/log \
        --weight_decay 0.05 \
        --seed 42 \
        --save_ckpt_freq 5 \
        --enable_deepspeed \
        --checkpoint_activations

--batch_size: batch size per GPU. Effective batch size = number of GPUs * --batch_size * --update_freq. So in the above example, the effective batch size is 192*16 = 3072.
--finetune: weight path of your pretrained models; please download the pretrained model weights in README.md
--task: coco_retrieval for COCO retrieval, flickr30k for Flickr30k retrieval
--lr: 2e-4 for COCO retrieval, 1e-4 for Flickr30k retrieval
--epochs: 15 for COCO retrieval, 20 for Flickr30k retrieval
--warmup_epochs: 3 for COCO retrieval, 5 for Flickr30k retrieval
--checkpoint_activations: using gradient checkpointing for saving GPU memory

The BEiT-3 large model can be finetuned on retrieval tasks using 2x16 V100-32GB:

bash

python -m torch.distributed.launch --nproc_per_node=16 --nnodes=2 --node_rank=$NODE_RANK \
       --master_addr=$MASTER_ADDR --master_port=$MASTER_PORT run_beit3_finetuning.py \
        --model beit3_large_patch16_384 \
        --input_size 384 \
        --task coco_retrieval \
        --batch_size 96 \
        --layer_decay 0.85 \
        --lr 5e-5 \
        --epochs 15 \
        --warmup_epochs 3 \
        --drop_path 0.2 \
        --sentencepiece_model /your_beit3_model_path/beit3.spm \
        --finetune /your_beit3_model_path/beit3_large_itc_patch16_224.pth \
        --data_path /path/to/your_data \
        --output_dir /path/to/save/your_model \
        --log_dir /path/to/save/your_model/log \
        --weight_decay 0.05 \
        --seed 42 \
        --save_ckpt_freq 5 \
        --enable_deepspeed \
        --checkpoint_activations

--batch_size: batch size per GPU. Effective batch size = number of GPUs * --batch_size * --update_freq. So in the above example, the effective batch size is 96*32 = 3072.
--finetune: weight path of your pretrained models; please download the pretrained model weights in README.md
--task: coco_retrieval for COCO retrieval, flickr30k for Flickr30k retrieval
