_pickle.UnpicklingError: invalid load key, '?'.

[ck321123]

When I was executing your program(DGL),I encountered the following error message:

_pickle.UnpicklingError: invalid load key, '?'.

I seem to have no way to solve it now,I don't know if there is an issue with the data or if there are other issues. Or maybe the version of pytorch is incorrect.The torch version I am currently using is 1.10, which supports cuda11.1.So is the version incorrect when loading the model? If so, I hope you can tell me the specific versions of each tool.If not, may I ask if you have encountered such a problem before? I hope you can help me.Looking forward to your reply!

Thanks.

Hey, please excuse the late answer, I had some deadlines I was working on. I added package versions to the environments. Can you recreate the base environment from scratch, and test again? Thank you!
