Scikits solver error with version 23.3

[ganmad]

Hi,

I tried using Scikits solver (both Dae and Ode) with latest version (23.3) and it throws an error that "ImportError: scikits.odes is not installed" while it has been installed.

Here is the confirmation that it has been installed:

pybamm_install_odes
/mnt/c/Users/ganesh/Documents/pybamm2/pybamm/pybamm/scikits_odes_setup.log
/home/ganmad/.local/lib was found in LD_LIBRARY_PATH.
--> Not updating venv activate or .bashrc scripts
Requirement already satisfied: scikits.odes in ./.tox/dev/lib/python3.8/site-packages (2.7.0)
Requirement already satisfied: scipy in ./.tox/dev/lib/python3.8/site-packages (from scikits.odes) (1.10.1)
Requirement already satisfied: numpy<1.27.0,>=1.19.5 in ./.tox/dev/lib/python3.8/site-packages (from scipy->scikits.odes) (1.24.2)

Here is the minimum example I tired:

import pybamm
model = pybamm.lithium_ion.DFN()

sksolver = pybamm.ScikitsDaeSolver()
sksolver2 = pybamm.ScikitsOdeSolver()
sim = pybamm.Simulation(model,solver=sksolver)
sim.solve([0, 3600])
sim.plot()

ImportError: scikits.odes is not installed

Am I missing anything?

Hi, are you running your script within the tox environment?

[ganmad]

Hi, Yes. I installed pybamm with tox and activated the environment. I am using pybamm on WSL with integrated VS code.

That sounds weird. Could you see if the library is actually installed -

pip show scikits.odes

Hi Sarnash, Thanks for your time. I realised that correct python kernel wasn't active on VS code, and now it is working fine after activating the environment. All looks good now. Thanks.
