gcc problem?

Hi, I am using the docker to build apex, but it looks like there are some errors. The following is the log:

 If your intention is to cross-compile, this is not an error.
By default, Apex will cross-compile for Pascal (compute capabilities 6.0, 6.1, 6.2),
Volta (compute capability 7.0), and Turing (compute capability 7.5).
If you wish to cross-compile for a single specific architecture,
export TORCH_CUDA_ARCH_LIST="compute capability" before running setup.py.

[sidak]

Hi! I am facing exactly the same issue. Were you able to resolve this? (My pytorch version is 1.2.0+cu92 and cuda is 9.2.148)
Thanks! :)

[drinkmooon]

The same issue too，with pytorch=1.2.0+cu100 and cuda is 10.0.1.
Will it help if i change gcc version？

[Stonesjtu]

My build failed on gcc-7.3.0, but works well on gcc-6.4.0. Any comment here?

The error message seems like glibc making some internal changes:

My build failed on gcc-7.3.0, but works well on gcc-6.4.0. Any comment here?

The error message seems like glibc making some internal changes:

This works! I tried to downgrade my gcc to gcc-6.5.0 and successfully installed apex. I am using Cuda 10.1 and Pytorch 1.6.0.

My build failed on gcc-7.3.0, but works well on gcc-6.4.0. Any comment here?
