hi, I'm getting this error during the backward propagation:

Traceback (most recent call last):
  File "/home/eriba/code/main.py", line 259, in <module>
    main()
  File "/home/eriba/code/main.py", line 235, in main
    loss.backward()

RuntimeError: cuda runtime error (77) : an illegal memory access was encountered at /home/eriba/software/pytorch/pytorch/torch/lib/THC/generic/THCTensorCopy.c:18

Any idea why would that happen ?

Hi,have you solved this problem?

edgarriba commented 7 years ago

@IngridLiu switched to official pytorch functionality

IngridLiu commented 7 years ago

@edgarriba Thanks~ Do you mean that I should install pytorch from the official website? I have installed pytorch follow the official website as bellow. Linux; pip; python 2.7; cuda 8.0;

My GPU is GeForce GTX 1050,but I met the same error in GTX1080.

Could you tell me how to fix it more detailly?

Thank you very much!
