I have a strange problem with Pytorch. When i use something torch functions with tensors like tensor.rehsape or torch.transpose, i don't have problem and all ok, even when i've created network all ok, but when i wanna train network my jupyter crashed.
.
i find where error,but i don't know why it is there and how it fix.

I installed pytorch using conda. I have Ubuntu 18.04. I don't have cuda.
