Multi30k data & Flickr30k entities

Multi30k data from here and here flickr30k entities data from here Here, We get multi30k text data from Revisit-MMT

cd fairseq_mmt
git clone https://github.com/BryanPlummer/flickr30k_entities.git
cd flickr30k_entities
unzip annotations.zip

# download data and create a directory anywhere

Extract image feature

1. Vision Transformer

# please read scripts/README.md to modify the code of timm firstly!
#        
python3 scripts/get_img_feat.py --dataset train --model vit_base_patch16_384 --path ../flickr30k

script parameters:

• dataset: choices=['train', 'val', 'test2016', 'test2017', 'testcoco']
• model: 'vit_base_patch16_384', that you can find in timm.list_models()
• path: '/path/to/your/flickr30k'

2. DETR

# please run scripts/get_img_feat_detr.py to download DETR offical code and model firstly
# then modify detr.py (in DETR offical code) to return image feature according to the above image
#        
python3 scripts/get_img_feat_detr.py --dataset train --path ../flickr30k

script parameters:

• dataset: choices=['train', 'val', 'test2016', 'test2017', 'testcoco']
• path: '/path/to/your/flickr30k'

Train and Test

1. Preprocess(mask1 as an example)

src='en'
tgt='de'
mask=mask1  # mask1, mask2, mask3, maskc(color), maskp(character)
TEXT=data/multi30k-en-$tgt.$mask

fairseq-preprocess --source-lang $src --target-lang $tgt \
  --trainpref $TEXT/train \
  --validpref $TEXT/valid \
  --testpref $TEXT/test.2016,$TEXT/test.2017,$TEXT/test.coco \
  --destdir data-bin/multi30k.en-$tgt.$mask \
  --workers 8 --joined-dictionary \
  --srcdict data/dict.en2de_$mask.txt

sh preprocess.sh to generate no masking data

2. Train(mask1 as an example)

you can run train_mmt.sh instead of scripts above.

3. Test(mask1 as an example)

#sh translation_mmt.sh $1 $2
sh translation_mmt.sh mask1 vit_base_patch16_384  # origin text is mask0

script parameters:

• $1: choices=['mask1', 'mask2', 'mask3', 'mask4', 'maskc', 'maskp', 'mask0']
• $2: 'vit_base_patch16_384', that you can find in timm.list_models()
