same error for me here too, any hints? Also running on windows like the above.

[rmchale]

Running on M1 Mac. Any suggestions?

[andrehafner]

it's a python 3.11 issue with one of the libraries. drop to 3.10 and it should work.

Python 3.11 seems to be causing problems with nemo, downgrade and it should be fine
