# Python code

Environment details

Google Colab
T4

Other/Misc.

Initially thought the issue is with relative path to files in Colab, but all leads to this exception so far

I had a similar issue and solved by using:

from physicsnemo.sym.hydra.utils import register_amp_configs
register_amp_configs()  # Must call before loading hydra config
