Hi,

I am opening an issue here since I am trying to run train_i3d.py, and I keep getting the same error. After trying a few things, it does not work. Here is the error, could anyone help me out please?

The error occurs due to the program continues to read frames though it has already reached the end of the video file.
For example, the following video sample is very short, not enough 27 frames to capture: https://www.signingsavvy.com/signs/mp4/7/7169.mp4

I am considering about solution: Check the returned value of VideoCapture.read() function
for offset in range(num): success, img = vidcap.read() if not success: break w, h, c = img.shape
Let's try and share the result

Another common cause is your local copy of the dataset misses some video files. Do you use official WLASL release or download from somewhere? Note that re-distribution of WLASL is strictly prohibited.
