I faced similar issue when trying to install spconv.

File "/home/kmario23/anaconda3/envs/py38/lib/python3.8/site-packages/torch/_ops.py", line 105, in load_library
    ctypes.CDLL(path)
  File "/home/kmario23/anaconda3/envs/py38/lib/python3.8/ctypes/__init__.py", line 373, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: libcublas.so.10: cannot open shared object file: No such file or directory

Installing the cuda toolkit version 10.1 inside the specific environment resolved the issue:

$ conda install -c anaconda cudatoolkit=10.1
