StopIteration - Train audio_lm3d_syncnet [Training Error]

[NithinJangid]

When i ran the CMD:
CUDA_VISIBLE_DEVICES=0 python tasks/run.py --config=egs/os_avatar/audio_lm3d_syncnet.yaml --exp_name=audio_lm3d_syncnet --reset.

i am getting StopIteration Error and when i checked the dataloader using len(dataloader) the length is 0, i dont know why
