Does this code support CUDA 11.X

I have tried to compile pointops with no success.

The following are the command prompts, would be really appreciated it if you could help.

found the issue.

change all

#define CHECK_CUDA(x) AT_CHECK(x.type().is_cuda(), #x, " must be a CUDAtensor ")
#define CHECK_CONTIGUOUS(x) AT_CHECK(x.is_contiguous(), #x, " must be contiguous ")
#define CHECK_INPUT(x) CHECK_CUDA(x);CHECK_CONTIGUOUS(x)

to

#define CHECK_CUDA(x) TORCH_CHECK(x.is_cuda(), #x, " must be a CUDAtensor ")
#define CHECK_CONTIGUOUS(x) TORCH_CHECK(x.is_contiguous(), #x, " must be contiguous ")
#define CHECK_INPUT(x) CHECK_CUDA(x);CHECK_CONTIGUOUS(x)

change all

cudaStream_t stream = THCState_getCurrentStream(state);

to

cudaStream_t stream = at::cuda::getCurrentCUDAStream().stream();

I try this and still get the error below:

 File "/home/aumam/anaconda3/envs/pytorch1.4/lib/python3.6/distutils/ccompiler.py", line 574, in compile
    self._compile(obj, src, ext, cc_args, extra_postargs, pp_opts)
  File "/home/aumam/anaconda3/envs/pytorch1.4/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 288, in unix_wrap_compile
    "'-fPIC'"] + cflags + _get_cuda_arch_flags(cflags)
  File "/home/aumam/anaconda3/envs/pytorch1.4/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 1027, in _get_cuda_arch_flags
    raise ValueError("Unknown CUDA arch ({}) or GPU not supported".format(arch))
ValueError: Unknown CUDA arch (8.6) or GPU not supported

I use cuda 10.1, python 3.6.6 and pytorch 1.4.0 on Ubuntu 20.04. I already tested on 3090 and a5000 GPU and got same error messages.
Any suggestion?
Thanks!

This package has been used by many other repositories as well and several changes are made to meet different versions of cuda, torch, etc.

If this doesn’t work, maybe looking into some latest repos such as https://github.com/guochengqian/PointNeXt and using their version would be helpful
