program stuck when creating data loader

[youcaiSUN]

Hi tengda,
I want to reproduce the result of infonce on UCF101. However, when I ran the code (in the section of "InfoNCE pretrain on UCF101-RGB", I did not change anything), the program stuck when creating data loader.
Could you help me to figure out this problem? Thanks very much!
Below is the console output:

`...

module.encoder_k.2.weight False
module.encoder_k.2.bias False
module.encoder_k.4.weight False
