@mrgloom If you install pytorch in conda environment, you need to make sure that apex is compiled with the same version of cuda that conda install. check cuda version in conda envrionment by

conda list|grep cuda

then compile apex with

CUDA_HOME=<path to cuda same version of the one installed by cuda> python setup.py install --cuda_ext --cpp_ext

make sure to remove build dir before recompiling.

@mrgloom The recommended way of installing Pytorch (for cpp/cuda extensions to work) is that the version of Cuda you have locally (which will be used to build extensions) is the same as the version that was used to build the Pytorch binaries you are installing. In your case Cuda 10.0 was used to compile the Pytorch binaries, but you have 10.1 locally (which is being used to compile the extensions). This is probably ok, and the warning doesn’t matter. If you don’t get any runtime errors about undefined symbols, I wouldn’t worry about it.

In general, there are several ways you can ensure that the version of Cuda used to compile the Pytorch binaries is the same as the local version of Cuda that will be used to build extensions:

  1. If your local cuda install is X.X, make sure you pip or conda install the cuda X.X version from https://pytorch.org/.
  2. Build Pytorch from source locally. You will also need to install cudnn locally beforehand. This will ensure that whatever version of nvcc is used to compile Pytorch is also used to build extensions.
  3. Install Apex in a Docker container. You will also need to run the container with nvidia-docker. Options include:
    • Nvidia Pytorch containers from NGC. These come with apex preinstalled, but that version may be out of date, so you may want to pip uninstall apex; git clone apex; cd apex; pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" .
    • Any of the official Pytorch -devel Dockerfiles. These do not come with Apex preinstalled, but you can git clone apex; cd apex; pip install -v --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" . within any of the images tagged with -devel.

I still don’t understand why the extensions are failing to compile with 9.0 and 9.1. Making sure #include <torch/extension.h> does not appear in any apex/csrc/*.cu files was sufficient to fix the build errors for us.

Hi @axiqia,

you might encounter a silent bug in the current PyTorch binaries, which seem to downgrade to CUDA9, even if CUDA10 was specified. This issue is being tracked here.

Could you use conda to intall PyTorch or use the stable/nightly pip install?

But looks like I still have I problem:

Warning: Torch did not find available GPUs on this system.
 If your intention is to cross-compile, this is not an error.

torch.__version__  =  1.0.1.post2
No CUDA runtime is found, using CUDA_HOME='/usr/local/cuda'

Warning:  Cuda extensions are being compiled with a version of Cuda that does not match the version used to compile Pytorch binaries.

Pytorch binaries were compiled with Cuda 10.0.130

What is recommended way of installing pytorch?

Couple of fixes were necessary here. 1. The old scale_check_overflow_kernel is no longer used in the new branch. 2. @ngimel pointed out that nvcc 9.0 cannot handle torch’s extension.h for some reason (unsupported outlandish c++ coming from pybind11, it seems).

I removed the dead code to fix 1. and @ngimel removed extension.h from where nvcc 9.0 was choking on it. Try to pull the latest master and rebuild, and let us know if you still see errors.

@OverFlow7 Hi, compiling cuda/cpp extension needs nvcc, which is not available in conda. Also, pytorch check CUDA_HOME environment variable for cuda libs. So, maybe you could try to compile in virtualenv, set CUDA_HOME if you wanna use other location other than /usr/local/cuda. I’m not sure how to compile cuda/cpp extension in conda environment, maybe we could still install pytorch and cudatoolkit in conda environment, and compile apex with the same version cuda of the one installed in conda environment by setting CUDA_HOME?

@ptrblck Got it. Thank you for your kind reply.

I create a package for ArchLinux, see https://github.com/archlinuxcn/repo/blob/master/archlinuxcn/python-apex-git/PKGBUILD for how to build with the latest cuda & pytorch availabel in archlinux’s official repo.

have the same error under the same environment with @Mitko-Kerezov but I have to use cuda 9.0 instead of 10.1. Is there any way to make it work with ubuntu 18.04 + cuda 9.0?

By the way, I coundn’t find any way to install gcc 5.4 like @mcarilli suggested

@OverFlow7 Are you seeing the same sort of errors that @terribilissimo saw that made me suspect pybind11, e.g.

/usr/include/c++/6/tuple:502:1: error: body of constexpr function ‘static constexpr bool std::_TC<<anonymous>, _Elements>::_NonNestedTuple() [with _SrcTuple = std::tuple<at::Tensor, at::Tensor, at::Tensor, at::Tensor>&&; bool <anonymous> = true; _Elements = {at::Tensor, at::Tensor, at::Tensor, at::Tensor}]’ not a return-statement
     }
/usr/include/c++/6/tuple:495:244: error: wrong number of template arguments (5, should be 2)
       return  __and_<__not_<is_same<tuple<_Elements...>,

Also, did you build pytorch 1.01 from source with cuda 9.0, or install via the pip or conda package?

Hello i have a smiliar error (Ubuntu 18.04, pytorch 1.01 , cuda 9)

error: command '/usr/local/cuda-9.0/bin/nvcc' failed with exit status 1

i did try to reinstall with pip uninstall apex; git clone https://github.com/NVIDIA/apex.git; cd apex; python setup.py install --cuda_ext --cpp_ext

but it still isn’t working.

Mmhh thanks, I’ll try. But for reasons too long too explain in details, I’d like apex to work without docker containers.
