PyBaMM import error - Cannot run anything

[abhishek-appana]

Hello,

I am running Python 3.11.8 and installed PyBaMM 24.1 using pip on a Windows system. Earlier I was using Python 3.10 and everything was fine. But I am getting the below error after upgrading Python.

When I run import pybamm, it gives me the error:

ModuleNotFoundError: Optional dependency pybtex.database is not available. See https://docs.pybamm.org/en/latest/source/user_guide/installation/index.html#optional-dependencies for more details.

I tried installing pybamm using pip install pybamm[all]. I was still getting this error. How do I resolve this?

That is weird. You should not get this error on just importing pybamm even if you don't have pybtex installed. Could you post the entire logs + executed code with and without installing pybamm with [all]? Please also post the output of python -m pip list.

Thank you for the response!

I uninstalled all the Python libraries, purged the pip cache, verified that there was nothing installed, and ran pip install pybamm [all].

Now the library is loading without an error. I had been doing the same thing for 3 hours and it was throwing me that error. I have no clue how it's running now!

Anyway, thank you for the help!
