Describe the bug

hi，I downloaded the ntu60 dataset and took a video of s001 (len=332). And the skeletal point annotations of the S001 video (len=380, including the 48 annotations of the 'S001C003P008R002A005' video) are saved. Only the dataset path has been changed, and the other training parameters are the defaults. But there were /anaconda3/envs/mmcv/lib/python3.8/site-packages/decord/video_reader.py", line 132, in _validate_indices raise IndexError('Out of bound indices: {}'.format(indices[indices >= self._num_frame])) Snipaste_2023-12-25_11-40-12
