I don't know what's the problem and how to fix it??
my environment is cuda9.0, gcc4.9.2, torch1.1
thanks a lot !

I have tried few different combinations of versions of cuda, gcc, torch. The versions which finally worked for me are:
gcc 5.5.0, pytorch 1.4.0, cuda 10.1, python 3.8

I used the following conda command to install the dependencies:
conda install pytorch==1.4.0 torchvision cudatoolkit -c pytorch

Not sure whether gcc version is needed to be changed, but here are instructions what I used to change the version:

Iuse a windows10 pc and follow your suggestion，but here is a another error. Here is the question
error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.16.27023\bin\HostX86\x64\link.exe' failed with exit status 1120
my environment is pytorch 1.4.0, cuda 10.1, python 3.6

Thank you so much for sharing your detailed environment. I just discovered that the pytorch and gcc version is very important to make it compile successfully: gcc >= 4.9.
