There is one more thing to fix to pass the build.

==> Building Python 3
Traceback (most recent call last):
  File "", line 5, in <module>
    from pip._internal import main as pipmain
ModuleNotFoundError: No module named 'pip'
==> ERROR: A failure occurred in build().

Please add python-pip to makedepends.

@petronny you're right. Fixed.

No CUDA runtime is found, using CUDA_HOME='/opt/cuda'
Traceback (most recent call last):
  File "", line 64, in <module>
  File "", line 43, in check_cuda_torch_binary_vs_bare_metal
    torch_binary_major = torch.version.cuda.split(".")[0]
AttributeError: 'NoneType' object has no attribute 'split'

Please change python-pytorch to python-pytorch-cuda.

@petronny Thanks for the suggestion. I Updated the PKGBUILD.

petronny commented on 2019-08-05 03:59

Also, git should be in makedepends.

petronny commented on 2019-08-04 05:48

It shouldn't be an any package since it depends on cuda.
Please set arch to ('x86_64').

Please check Currently, I don't have a solution with pytorch/pytorch-cuda in the community repo...

For now, I compile pytorch master myself...

I get this warning when I use apex.amp:

'Warning: multi_tensor_applier fused unscale kernel is unavailable, possibly because apex was installed without --cuda_ext --cpp_ext. Using Python fallback. Original ImportError was: ImportError('/usr/lib/python3.7/site-packages/ undefined symbol: _ZN3c105ErrorC1ENS_14SourceLocationERKSs')'

@leomao see syncbn for syncbn example. Actually, see this issue. It seems that pytorch appends -D_GLIBCXX_USE_CXX11_ABI=0 to compiler flags by default. I don't see a way to override it. And according to pytorch's PKGBUILD, there is no modify related to this flag. I believe that pytorch is build with -D_GLIBCXX_USE_CXX11_ABI=0, which is the default behavior of pytorch official configuration. So it would be OK to build apex extension with the same flag, aka -D_GLIBCXX_USE_CXX11_ABI=0. However, it's not. I try to build build apex with -D_GLIBCXX_USE_CXX11_ABI=1 by manually replace all -D_GLIBCXX_USE_CXX11_ABI=0 to -D_GLIBCXX_USE_CXX11_ABI=1 in /usr/lib/python3.7/site-packages/torch/utils/, and it works as expected. However, one should not expect to modify this during building apex with devtools, right?

Hi @hottea, thanks for reporting the issue. Could you provide a code snippet for testing? I just checked that the examples and tests ran without errors.
