Symbol not found Error

[AndreaCooper0]

I encounter an error when writing the following scripts.

from torch_sparse import SparseTensor

The error is

Traceback (most recent call last):

How can I handle this? thx.

I get a similar error with torch==1.10.0 but everything works with torch==1.9.0.

I installed torch-sparse from the wheel at this url:

https://data.pyg.org/whl/torch-1.9.0%2Bcpu/torch_sparse-0.6.12-cp39-cp39-linux_x86_64.whl

Note I'm using python 3.9

Keep in mind that you need to install from https://data.pyg.org/whl/torch-1.10.0+cpu when using PyTorch 1.10.
