The installation problem was finally solved, but the above problems occurred in the import. Can anyone help explain?

I also encountered the same problem. Under what conditions did you solve it?

[fcyx]

I was the problem was due to version mismatch, so I upgraded CUDA to 11, and so did pytorch. After that, you can install other plugins that correspond to them.

@fcyx Thank you. I have solved the problem. (Deployment: CUDA11.1, torch 1.8.1+cu11.1, GeForce RTX 3090)
