Likely hi-pri if it repros

Can not reproduce it on my end, so removing hi-pri for now (but will add it back if more users encounter it):

#97748

Solution: Downgrade Python version. The recommended version is 3.8, but please be aware not to go too low. Refer to the discussion at https://discuss.pytorch.org/t/pytorch-2-0-supported-python-version/174962.

I just resolved the same error. Initially, my CUDA version was 12.0, PyTorch version was torch 2.0.1 for CUDA 11.8, and Python versions were 3.10.0 and 3.9.0, but all gave me an error. I thought the issue was due to the compatibility between PyTorch and CUDA versions, so I tried installing CUDA 11.8. The result proved that the issue was not due to CUDA, although this might also be a potential important factor.

Now, my CUDA version is 11.8, PyTorch version is torch 2.0.1 for CUDA 11.8. I failed to load torch using Python 3.9.0, but successfully loaded it using Python 3.8.8.

@craii are you still having this issue ? I tried reproducing it with your configuration (python 3.10 and pytorch 2.0.1+cu117) and did not run into this issue. According to this pytorch post, the python, cuda and pytorch versions used by you should work well together.
