Installation error: nvc unknown switch

[mangelett]

Hi,

I try to install inplace_abn with the command python3 -m pip install inplace_abn. But it fails because of unknown switch:

      No CUDA runtime is found, using CUDA_HOME='/softs/nvidia/hpc_sdk/Linux_x86_64/22.11/cuda/11.8/'

      Your compiler (/softs/nvidia/hpc_sdk/Linux_x86_64/22.11/compilers/bin/nvc++) is not compatible with the compiler Pytorch was
      built with for this platform, which is g++ on linux. Please
      use g++ to to compile your extension. Alternatively, you may
      compile PyTorch from source using /softs/nvidia/hpc_sdk/Linux_x86_64/22.11/compilers/bin/nvc++, and then you can also use
      /softs/nvidia/hpc_sdk/Linux_x86_64/22.11/compilers/bin/nvc++ to compile your extension.

The CUDA version is 11.8: see the return of nvcc --version:

I tried to installed torch with the specific CUDA version: python3 -m pip install torch==2.0.1+cu118 torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118` but it didn't solve the problem.
Is there a way to modify the compilation flags ?
