RuntimeError: Error compiling objects for extension

Hi, thanks for your excellent work. I met some problems when running python setup.py install:

running install
running bdist_egg
running egg_info
writing torch_butterfly.egg-info/PKG-INFO
writing dependency_links to torch_butterfly.egg-info/dependency_links.txt
writing top-level names to torch_butterfly.egg-info/top_level.txt

I use :
python 3.7
pytorch 1.8.0
CUDA 10.2
Do you have any ideas how to solve this problem? Thank you.

Hi, thanks for trying our code.
Which OS and gcc version are you using?

[Mandy-77]

gcc version 7.4.0
Linux 5.0.0-23-generic x86_64

[tridao]

Does the machine you compile on have a GPU? Does it have access to the CUDA compiler (nvcc)?
Or are you just using the CPU version?

[Mandy-77]

Yes, it has the CUDA compiler, when I type nvcc --version I get Cuda compilation tools, release 10.2, V10.2.89.

Thanks, let me try to reproduce on my end.

Thanks a lot for your help!
