How to solve FileNotFoundError problem？

[forestbat]

When I run test code in this article，it occurs mistake like this：
FileNotFoundError: Could not find module 'C:\Python310\Lib\site-packages\torch_sparse\_convert_cuda.pyd' (or one of its dependencies). Try using the full path with constructor syntax.
And I tried to install wheel from this link, however the main function still crashed with FileNotFoundError.
I'm sure there is _convert_cuda.pyd in torch_sparse directory.
And when I run python -c "import torch; print(torch.__version__)"
the output is: 1.12.1+cpu

Is there any connection with torch version? How to solve my problem?

How did you install torch-sparse? Does import torch_sparse work for you?

Now I use pyg's cpu version，it tells me this：

[rusty1s]

Never seen this error before. Can you debug the content of out before line 107?

[forestbat]

exception: (<class 'ValueError'>, ValueError("too many dimensions 'matrix'"), <traceback object at 0x000002803459D880>)

I don‘t know how to get debug content with txt，so I can only give you a picture.

[rusty1s]

Mh, this is weird. Looks to be an issue with pickle. What is the version of pickle you are using?

[forestbat]

python -c "import pickle; print(pickle.format_version)"
4.0
