When I try to compile c extension by using python bulid.py, it always raise error:
I search in pytorch forums but get no answers.
And I find this link https://github.com/jwyang/faster-rcnn.pytorch/issues/235 discuss the same problem and someone give some solution — switch pytorch to 0.4.0
I want to know is there some better solution, because it’s annoying to install another version.
Hi,
Could you post the compilation log.
This error means that there was an error during the compilation, could you report it here please?

It looks like it did not compiled nnd_cuda.cu. is it specified properly in your setup.py script? Is your user allow to write files on disk?
Thanks for your help!
I think I may know where something went wrong. I am sorry that I haven’t read the compilation log carefully.
