Train issue

[rebotnix]

This project is really interesting.

I tried to train the model, but i always get a random list index out of range error during the training phase.

I used torch 1.2 till 1.3.1, cuda 10.1, always the same error.

Anyone has an idea how to fix that?

python3 train.py --dataset_path data/UCF-101-frames/ --split_path data/ucfTrainTestlist --num_epochs 200 --sequence_length 20 --img_dim 112 --latent_dim 512 --batch_size 64

Same error as @rebotnix

[pcshih]

I do the vacant frame check

video_frame_paths = glob.glob(os.path.join(opt.dataset_frames_path, "*", "*")) for i, video_frame_path in enumerate(video_frame_paths): video_frame_len = len(glob.glob(os.path.join(video_frame_path, "*"))) if(video_frame_len==0): print(i, video_frame_path)
and extract frames again

@pcshih I have the same error. Which file have you made the changes to?

[key-cc]

same error, have you solved the error yet? @rebotnix @pcshih
