freeze at the beginning of training

[badarrrr]

my model appears to freeze at the beginning of training without any errors or termination messages.
I have found the same Error in the issues, but I can't find "torch_extensions" ...The solution of that issue doesn't work.
Who can help me?

1)the issue could be from nerfacc, see nerfstudio-project/nerfacc#260
2)could also be a good idea to reduce the number of callbacks in launch.py, especially if your codebase is large, adding the CodeSnapshotCallback tends to slow things down
