$ git clone https://github.com/snaredataset/snare.git

$ virtualenv -p $(which python3) --system-site-packages snare_env # or whichever package manager you prefer
$ source snare_env/bin/activate

$ pip install --upgrade pip
$ pip install -r requirements.txt

Edit root_dir in cfgs/train.yaml to reflect your working directory.

Download pre-extracted image features, language features, and pre-trained checkpoints from here and put them in the data/ folder.

$ python train.py train.model=zero_shot_cls train.aggregator.type=maxpool 

$ python train.py train.model=single_cls train.aggregator.type=maxpool 

$ python train.py train.model=rotator train.aggregator.type=two_random_index train.lr=5e-5 train.rotator.pretrained_cls=<path_to_pretrained_single_cls_ckpt>

Run scripts/train_classifiers.sh and scripts/train_rotators.sh to reproduce the results from the paper.

To train the rotators, edit scripts/train_rotators.sh and replace the PRETRAINED_CLS with the path to the checkpoint you wish to use to train the rotator:

PRETRAINED_CLS="<root_path>/clip-single_cls-random_index/checkpoints/<ckpt_name>.ckpt'"

If you want to extract CLIP vision and language features from raw images:

1. Download models-screenshot.zip from ShapeNetSem, and extract it inside ./data/.
2. Edit and run python scripts/extract_clip_features.py to save shapenet-clipViT32-frames.json.gz and langfeat-512-clipViT32.json.gz

Please send your ...test.json prediction results to Mohit Shridhar. We will get back to you as soon as possible.

Instructions:

• Include a name for your model, your team name, and affiliation (if not anonymous).
• Submissions are limited to a maximum of one per week. Please do not create fake email accounts and send multiple submissions.
