Basic problem getting pyelmer running

kottonau commented 2 years ago

On windows 10, python 3.10, installed pyelmer with pip command, we are getting the following error after trying to run one of the example scripts:

Traceback (most recent call last):
  File "path to\crystal_growth_2d.py", line 14, in <module>
    from pyelmer import elmer
  File "path to\Python310\site-packages\pyelmer\__init__.py", line 2, in <module>
    from . import elmer, execute, gmsh, post
  File "path to\Python310\site-packages\pyelmer\gmsh.py", line 4, in <module>    
    import gmsh
  File "path to\Python310\site-packages\gmsh.py", line 53, in <module>
    lib = CDLL(libpath)
  File "path to\lib\ctypes\__init__.py", line 364, in __init__
    if '/' in name or '\\' in name:
TypeError: argument of type 'NoneType' is not iterable

Any hints?

This seems to me like an issue with gmsh, which is used in the simulation setup.

Does import gmsh lead to the same error?

kottonau commented 2 years ago

Yes indeed, same error. Do we need to use a specific version?

Name: gmsh
Version: 4.10.3

I've been mostly working with version 4.8.4 (I used it when I set up the tutorial case), recently I updated to 4.10.1, both worked well. I'd recommend to first try 4.10.4 (it was released yesterday), if that doesn't help I'd go for the older versions.

Maybe there is already a corresponding gmsh issue?

Reinstalled python, all seems to work now

python: 3.10.5
gmsh: 4.10.4

Looking forward to working with pyelmer!

closing issue.
