spconv: Import Error

Thanks for your excellent work!

I am trying to install Spconv 2.0 with the latest pytorch 1.10.0 and Cuda 11.4 or Cuda 11.5. However, I meet different errors when I try to install Spconv with pip install spconv-cu114 or building from source.

If I use pip install spconv-cu114, when I try to run import spconv.pytorch as spconv, I met the following error message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/__init__.py", line 8, in <module>
    from spconv.pytorch.conv import (SparseConv2d, SparseConv3d, SparseConvTranspose2d,
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/conv.py", line 29, in <module>
    from spconv.pytorch.core import IndiceData, SparseConvTensor
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/core.py", line 17, in <module>
    from .core_fx import *
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/core_fx.py", line 20, in <module>
    from torch.fx.symbolic_trace import ProxyableClassMeta
ModuleNotFoundError: No module named 'torch.fx.symbolic_trace'

But when I turn to building spconv from source, I met another import error as following:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/__init__.py", line 7, in <module>
    from spconv.pytorch import ops
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/pytorch/ops.py", line 22, in <module>
    from spconv.algo import AlgoHint, ConvAlgo
  File "/home/du014/anaconda3/envs/pointcloud-mk2/lib/python3.8/site-packages/spconv/algo.py", line 18, in <module>
    from spconv.core_cc.cumm.gemm.main import GemmAlgoDesp, GemmMainUnitTest, GemmParams
ModuleNotFoundError: No module named 'spconv.core_cc'

BTW, I have already install cum-cu114.

Could you help me with this import bug?

looking forward to a new version ,I also have this issue , File “D:\pythoncoder\Anaconda3\lib\site-packages\spconv\algo.py”, line 18, in <module> from spconv.core_cc.cumm.gemm.main import GemmAlgoDesp, GemmMainUnitTest, GemmParams ModuleNotFoundError: No module named ‘spconv.core_cc’

Putting my solution for reference.

File "/opt/conda/lib/python3.7/site-packages/spconv/conv.py", line 181, in forward
use_hash=self.use_hash)
File "/opt/conda/lib/python3.7/site-packages/spconv/ops.py", line 95, in get_indice_pairs
int(use_hash))
ValueError: /home/sid/spconv/src/spconv/spconv_ops.cc 87
unknown device type

I got this error because I had previously compiled a different version of spconv and was reusing the build folder. Removing the build folder and building the wheel again from scratch solved the issue.

@sharknow here, you can find it in commit history.

@hongsukchoi this bug should be fixed in spconv 2.0.2, make sure your version is spconv 2.0.2. if you can’t find spconv 2.0.2 in pip, use official pypi by pip install spconv-cuxxx -i https://pypi.python.org/simple. pypi mirrors need time to synchronize new packages.
