Couldn't find program: 'bash'

[Tangzl922]

Hi,
when I run the tutorial file for parameter management I got this error

I also read this issue #1697 and tried to use pybamm.parameters_cli.edit_parameter, but this still doesn't work.

Here is my parameter path, maybe helpful for you. And my version is 22.5.

Regards

The parameters_cli functions are not supported in Windows. You can still define the folder structure manually for the parameters to work.

I will transfer this to a discussion for the record.

Thanks for the reply. It seems that 'bash' still doesn't work for me, so I have no idea how to edit the parameters without changing the default parameter set.

You can install git with git bash (usually installed by default with git). This would allow your notebooks to access bash and run the commands using it.

Alternatively, you can use %%cmd instead of %%bash. Note that this would require changing the bash commands in the notebook to cmd commands. For instance -

%%bash
if [[ ! -d "lithium_ion" ]]; then
echo "Directory lithium_ion does not exist."
fi

would change to -

%%cmd
@echo off
if exist "lithium_ion" (
  echo Directory lithium_ion exists 
) else (
  echo Directory lithium_ion does not exist
)

or something similar.

I have pushed a notebook identical to the original one, but swapping the bash commands with cmd commands on my fork here - https://github.com/Saransh-cpp/PyBaMM/blob/parameter-management-in-windows/examples/notebooks/parameterization/parameter-management.ipynb. You can download this and run it locally on Windows without any errors!

I am not sure if these commands should be in some way displayed to the users in the original notebook. This issue should go away once the cli functions are exposed!

Thanks for your answer, that really works for me!

@Saransh-cpp , thanks for your help. I tried the windows version notebook you provided in this note book . I get the error message "pybamm_edit_parameter" is not recognised as an internal or external command, operable program or batch file. I think there is a path issue with my spyder. Kindly help me resolve this issue.

Hi @Nithin3297. There have been considerable changes in PyBaMM since my comment, in fact, the parameter CLI has been deprecated. I would suggest that you go through the current documentation and ignore this notebook.
