liionpack solver 'type' KeyError

[frivollier]

I am looking for help with liionpack https://github.com/pybamm-team/liionpack

I am getting the following type KeyError while running all examples. (this is error from the example git home page readme.md)

Traceback (most recent call last): File "/Users/frivollier/software_local/BESSTools1/liionpack_DT/test.py", line 46, in <module> manager='casadi') File "/Users/frivollier/software_local/BESSTools1/venv/lib/python3.7/site-packages/liionpack/solver_utils.py", line 441, in solve setup_only=False, File "/Users/frivollier/software_local/BESSTools1/venv/lib/python3.7/site-packages/liionpack/solvers.py", line 317, in solve self.protocol = lp.generate_protocol_from_experiment(experiment, flatten=True) File "/Users/frivollier/software_local/BESSTools1/venv/lib/python3.7/site-packages/liionpack/protocols.py", line 30, in generate_protocol_from_experiment typ = op["type"] KeyError: 'type'
running on mac python 3.7

thanks for pointing me in the right direction for some help.

Regards,

I managed to get it to run on a Windows machine so I have a feeling it is an issue with casadi in a virtual environment on mac.
I am continuing to debug

Hi @frivollier

mac python 3.7

1. The newer versions of PyBaMM support Python 3.8 and 3.9; it is suggested to upgrade to either one of them to avoid installing an older version of PyBaMM.
2. There are some known issues with installing PyBaMM on M1/M2 mac. There are workarounds for this mentioned in [Bug]: Installing PyBaMM on M1 chip fails (both pip and install from source) PyBaMM#2346.

Could you also let us know the PyBaMM and liionpack versions you are trying to use? The libraries should work if both of them are on their latest versions -

python -m pip show pybamm liionpack

I will try to run on python 3.9

here are the versions that I have installed :
