Question about MinkowskiEngineBackend #444

Closed houyongkuo closed 2 years ago

houyongkuo commented 2 years ago

Hello! Thank you for your innovative work. But I found the following problem related to MinkowskiEngineBackend when import ME, I can't understand how this problem arises. It seems to be related to the virtual environment of anaconda. Hope to get help.

ImportError: /home/houyongkuo/.conda/envs/KSConvNet/lib/python3.8/site-packages/MinkowskiEngine-0.5.4-py3.8-linux-x86_64.egg/MinkowskiEngineBackend/_C.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZNK2at6Tensor7optionsEv

Thanks

I was using pytorch 1.10.2 before, when I switched to 1.9 or 1.10.0 this problem was solved, but another problem appeared: File "/home/houyongkuo/.conda/envs/KSConvNet/lib/python3.8/site-packages/MinkowskiEngine-0.5.4-py3.8-linux-x86_64.egg/MinkowskiEngine/__init__.py", line 53, in <module> from MinkowskiEngineBackend._C import ( ImportError: libc10_cuda.so: cannot open shared object file: No such file or directory

Where is the file MinkowskiEngineBackend, as I am getting an error which states :ModuleNotFoundError: No module named 'MinkowskiEngineBackend.C' when I tried cloning the repo!
