• python >= 3.6.10
• pytorch >= 1.7.1
• tensorboardX
• einops
• tqdm

• Download the CLIP pre-trained features of HMDB51 from here.

  Unzip the features, and put them under the ./feat folder.

• Download the pre-train model of HMDB51 from here, put it under the ./models folder.

  After the preparation work, the whole project should have the following structure:
