Requirements

• Python 3
• CUDA 10
• numpy
• tqdm
• easydict
• PyTorch (>1.0)
• torchvision
• coco-caption

Data preparation

1. Download the bottom up features and convert them to npz files

python2 tools/create_feats.py --infeats bottom_up_tsv --outfolder ./mscoco/feature/up_down_10_100

2. Download the annotations into the mscoco folder. More details about data preparation can be referred to self-critical.pytorch

3. Download coco-caption and setup the path of __C.INFERENCE.COCO_PATH in lib/config.py

4. The pretrained models and results can be downloaded here.

5. The pretrained SENet-154 model can be downloaded here.

Training

Train X-LAN model

bash experiments/xlan/train.sh

Train X-LAN model using self critical

Copy the pretrained model into experiments/xlan_rl/snapshot and run the script
