Hi,

I'll look into this. Could you please post the PyTorch version that you used?

This is very weird. I've pulled the same version of the pytorch build as you, I have the same nvcc version but compilation went fine. I'm investigating a bit further, but I wonder if it might be related to facebookarchive/caffe2#1898

Can you try doing something like

CUDA_HOST_COMPILER=/usr/bin/gcc-5 python setup.py build develop

[fmassa]

Oh, wait, what's your gcc version?

It seems that CUDA 9.0 doesn't support gcc 6.4.0

[gf19880710]

Hi, my gcc version is 6.4.0!

(maskrcnn_benchmark) gengfeng@ai-work-4:~/github/maskrcnn-benchmark$ gcc --version
gcc (Ubuntu 6.4.0-17ubuntu1) 6.4.0 20180424

so, which gcc version I should use?

[fmassa]

I'm using gcc 5.4.0 and it works fine here.

@fmassa I think CUDA9.0 just support gcc6 but not gcc7 which is default in Ubuntu18.04. I got this error to but no clue why

[lucasjinreal]

Currently my gcc version is 6.4

[fmassa]

@jinfagang according to the list I posted, CUDA 9.0 doesn't support gcc 6.4 either.
We use FindCUDA internally, so maybe if you specify CUDA_HOST_COMPILER to be a lower gcc version that should work??
I'd start trying to see if passing as an environment variable would work

@fmassa ,
Let me try 5.4.0 and gave you feedback later.
@jinfagang I use also Ubuntu18.04 which has gcc6 and gcc7(default).

[lucasjinreal]

@fmassa Using gcc5 by how?

[fmassa]

@gf19880710 if the environment flag doesn't work, you can add a line in setup.py to add the CUDA_HOST_COMPILER flag that I mentioned earlier.
Something like

'-DCUDA_HOST_COMPILER=/usr/bin/gcc5'

or the path to your gcc5

[gf19880710]

@fmassa OK, feedback to you later.

[lucasjinreal]

@fmassa I add that line to setup.py, but still got this:
