Issue installing pathsim-batt

[Demmatra]

Hi,

I am trying to learn PathSim in order to run lithium-ion battery simulations. However, I cannot manage to install pathsim-batt to access the battery blocks.

For now, I go to:
Blocks -> Toolbox -> Add Toolbox

Then, in the PyPi window, I enter pathsim-batt, but I get the following error: :Traceback (most recent call last):
File "/lib/python312.zip/_pyodide/_base.py", line 596, in eval_code_async

See: https://pyodide.org/en/stable/usage/faq.html#why-can-t-micropip-find-a-pure-python-wheel-for-a-package

Could you help me understand what I am doing wrong?

Thank you.

Hi,

yes the thing is that the deployed web version uses Pyodide as a backend which can only install packages that are native python or have wheels specifically built for it. Some of thr toolboxes are built on python packages that have c++ wheels. pathsim-batt is built on PyBaMM which is built on CasADi which doesnt run in Pyodide.

This isnt an issue with the local version that you can install through pip

pip install pathview

and then this exposes a cli to start the gui

pathview serve

this then uses your local python where you can install anything.

Hope this help
