unable to install spconv v1.2

[Lyan1997]

1. version

python 3.7
torch1.6.0 torchvision 0.7.0
cuda 10.1
cmake version 3.13.2

2.This is what I did:

• git clone https://github.com/traveller59/spconv.git --recursive

• sudo apt-get install libboost-all-dev

• python setup.py bdist_wheel

3.output error

Please help me!!!Thank you!

Do you have cuDNN installed?
Also it looks like you did not set the CMAKE_CUDA_COMPILER in the environment variables. You can edit the setup.py to add more options.
I had the similar issue and solved it by adding following line before subprocess.check_call in the build_extension function of setup.py (here):
cmake_args += ['-DCMAKE_CUDA_COMPILER=/usr/local/cuda/bin/nvcc']
