AssertionError Problems

[hb-9797]

Hi, sir
I meet a problem similar to issues"21"and"22“(https://github.com/schism-dev/pyschism/issues/21)。And install new packages as per reply 22(”conda install -c nesii -c conda-forge esmpy“)。
However, when I debug the programme, the same error is still reported. How to solve the problem?

1. Test code
   
2. Error

Hi @hb-9797, can you please execute conda list in your environment and paste the result here? I also noticed you're using pyschism on Windows, can you try it on a Linux platform and see if you run into the same issue? e.g. on WSL on Windows. I just tested installing it on my WSL2 using:

$ conda create -c conda-forge -n my_pyschism_env python=3.10 udunits2 cfdm cfunits
$ conda activate my_pyschism_env
$ pip install pyschism
$ python
>>> import pyschism

without any issues

[hb-9797]

Thanks for the reply, here is my conda list, "udunits2 cfdm cfunits" all three libraries are installed, I have not used them on Linux before, will try next.

I have this in my WSL environment (I create this environment from scratch with Python version matching yours) and it does not crash for me:

Specifically for cf-python, cfdm, cfunits, udunits2 it seems to match your versions. The only difference is from the build. Maybe that's an issues with Windows. I don't have a Windows environment to test it on, if you can, please test on your Windows WSL and see if you see the same issue.
