• For others, please refer to INSTALL.md of the official maskrcnn-benchmark repo.
• python setup.py build develop

Dataset Preparation

cd AE-WTN/datasets/openimages

# download the Open Images training annotations 
wget https://storage.googleapis.com/openimages/challenge_2018/train/challenge-2018-train-annotations-bbox.csv

## create symlinks (in datasets/openimages) to image directories of training and evaluation datasets

# Open Images (challenge/V4/V5) training images directory (about 1.58M images with all download parts combined)
# https://www.figure-eight.com/dataset/open-images-annotated-with-bounding-boxes/ (train_00.zip, train_01.zip, ...)
ln -s train /path_to_openimages_images/train

# Open Images (V4/V5) validation images (41,620 images)
# https://datasets.figure-eight.com/figure_eight_datasets/open-images/zip_files_copy/validation.zip
ln -s val_600 /path_to_openimages_images/validation

# Visual Genome (Version 1.2) images (108,079 images with part 1 & 2 combined)
# https://cs.stanford.edu/people/rak248/VG_100K_2/images.zip
# https://cs.stanford.edu/people/rak248/VG_100K_2/images2.zip
ln -s VG_100K /path_to_visualgenome_images

cd ../..

Training & Evaluation

By default, 4 GPU cards are utilized for training and evaluation.

Training checkpoints are stored in the same directory. Evaluation results are stored in the inference subdirectory.

cd experiment

# training
sh train.sh

# evaluate on the 3 evaluation datasets
sh test.sh

Pretrained model: download link (place it in the same directory before running evaluation)
