RuntimeError: The size of tensor a (91) must match the size of tensor b (90) at non-singleton dimension 2

[erikqu]

It seems like all my batches have some underlying issue where they're all off by one, I've seen other issues opened about this, but no proper explanation, could I get some help on this?

Failed during forward The size of tensor a (91) must match the size of tensor b (90) at non-singleton dimension 2

Verified text and wavs are both the batch size (16), all wavs are padded in this case to 84480.

Running into the same issue. Also checked that my sizes are consistent before processing.
RuntimeError: The size of tensor a (937) must match the size of tensor b (936) at non-singleton dimension 2
