Questions about freezing bn layer

[deepcharle]

Thank you for your excellent work! But I have some questions about the implementations. Could you give an example to better illustrate how you disable the bn layers? If you only set model.eval() or set the requires_grad=False for the bn weight and bias or both? Further, how many instances have you chosen in your main training phase as there tends to be more than 1 instances in the video. Thanks for your reply.
