You might have to upgrade your pymatgen version. Make sure to run the latest version.

my version is pymatgen-2024.8.9. Isn’t this the latest version?
or should I degrade the version??

when I use jupyter notebook to run the code
from mp_api.client import MPRester
the error I get is as follows:
ImportError: cannot import name ‘SymmetryUndeterminedError’ from ‘pymatgen.symmetry.analyzer’ (/opt/anaconda3/envs/fresh_env/lib/python3.9/site-packages/pymatgen/symmetry/analyzer.py)

its that same error

I get the same error as well using pymatgen-2024.8.9. with python3.9

The latest pymatgen version is 2024.10.29. You might have to upgrade your python version to 3.10 or later.

Thank you. Resolved when I upgraded to python 3.12
