River Runoff -

[armish2]

Hello Team,

I am trying to learn particle modeling. I am trying to replicate the example 'river runoff'.

UnboundLocalError: cannot access local variable 'io_module' where it is not associated with a value.

In basemodel.py file, I tried to assign a value for 'io_module ' variable. Still I am facing error.

It seems there is something wrong with your installation. Did you follow the steps on https://opendrift.github.io/install.html ?

It is probably best to not make any modifications in basemodel.py, or any of the core files.
You can check with git status what has been modified locally.

To test your installation, you can run pytest from the main opendrift folder.

Thank you for getting back to me.
Yes, I followed the same steps - https://opendrift.github.io/install.html

when I run pytest from miniconda prompt, I get error -
