Hi,
This is just to ensure that we pick a random video from the training set as opposed to processing videos sequentially in the order that they occur in the dataset. You may also be confused, thinking why do we select a random index here, and also when we create the dataloader, we set shuffle = True. The result for this lies in the fact that this line that you are referring to is contained in a while loop. This means that if it picks a random video and there happens to be some issue with it (such as containing few than 15 frames) or an error occurred when loading the image or audio window, this will cause us to loop again, picking another random video until we do not encounter any issues. Hope that makes sense.
Thanks your great work. I'm a little confused about the code in the training lip-sync Expert Discriminator section of your project. https://github.com/Rudrabha/Wav2Lip/blob/b9759a3467cb1b7519f1a3b91f5a84cb4bc1ae4a/color_syncnet_train.py#L69-L71
Why is a random number assigned to the variable
idx
here, which is counterintuitive
