Thank for your work! Please comment,when training ,report another error.

Thank you for reporting! Could you please provide the full error trace? Thank you. (It is always ideal to have the CUDA_LAUNCH_BLOCKING=1 flag when running, so any low-CUDA errors shall be triggered)

Thank you for you reply! The complete error appears below.

@matyasbohacek Hi have you resolved this error ? I am also getting the same error

[RodGal-2020]

I'm having the same problem, is there a solution for it?

[RodGal-2020]

Hey, I have found a solution!

Go to datasets/czech_slr_dataset.py, and around line 105, find the following:

label = torch.Tensor([self.labels[idx] - 1])

That -1 is the cause of our problems, because while working with WLASL100, labels go from 0 to 99 and, as a result, when we call the class CzechSLRDataset, we recieve something like tensor([[-1]]), but there is no class labelled with -1. This explains the CUDA error and the t >= 0 & t < num_labels.

Taking that into account, the following fix worked for me:

label = torch.Tensor([self.labels[idx]]) # Just drop the "-1"

Hope this helps! :D
