How to deal with this error? Thanks

[yrwangxd]

I use 100 videos to check if I can run this project,but while training I got this error. I can't find what is wrong. Help me ,please.Thanks.

This error is due to "dataloader.py". You need to change the getitem function of the class VideoDataset.According to the "idx", get your video id
video_feat = np.load(os.path.join(self.feats_dir[0], your video id + ".npy"))
captions = self.captions[your video id]['final_captions']
