Hello everyone,
I’ve been decoding for many hours but I still haven’t been able to figure out why.


Torch.abs() returns unknown error when running in terminal, with PyTorch Lightning, and Wandb (if that matterrs).

no NaN values
range is 0,1.
size is (20,1600,16)
tensor sum to 12700, meaning that we probably have a Sparse Tensor
* This “sparse tensor” thing is the only cause for the error that came to mind, as I find several relevant posts online.



F.elu(x) produces unknown error.

x is also range (0,1), with no NaN values.
this is taking place after the two down-sampling stages, in the first up-sampling stage.
within the first up-sampling stage, this is after 2 convolutional layers + 2 F.elu(x) + 3rd convolutional layer.



I am very puzzled…Could both of these be due to memory error?
