_version_cpu.so: undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSs

I follow the instruction and run the `python script/inference.py`. Then I got this error:
```
/conda/envs/diffpack/lib/python3.8/site-packages/torch_cluster/_version_cpu.so: undefined symbol: _ZN5torch3jit17parseSchemaOrNameERKSs
```
