[Python] PyNEC fails to import (PyInit__PyNEC error) on WSL Ubuntu with Python 3.12/3.11/3.9

I’m trying to use PyNEC (Python bindings for NEC2++) on a fresh Windows 11 WSL2 Ubuntu 24.04 setup. My goal is to call NEC directly from Python, instead of shelling out to the nec2++ CLI and parsing CSV output.

What I’ve done & what's happened so far:

• For each of Python 3.12, 3.11, and 3.9 in succession I created clean virtual environments each time and installed with:

pip install --upgrade pip setuptools wheel
pip install "numpy<2" cython
pip install PyNEC

• 
  Verified install completes (Successfully installed PyNEC-1.7.3.6).
  
  
• 
  In site-packages, I only see _PyNEC.cpython-...so, no PyNEC/ directory.
  
  
• 
  import _PyNEC or from _PyNEC import NEC fails with:`
  

ImportError: dynamic module does not define module export function (PyInit__PyNEC)

• Probing with importlib.util.find_spec shows _PyNEC is present but PyNEC is not.

What I’ve researched

• 
  PyPI wheels show PyNEC worked for Python 3.9 but failed for 3.11.
  
  
• 
  Examples online (e.g. afiskon/pynec-examples) use import PyNEC, but my install never provides that module.
  
  
• 
  I’ve also tried installing the NEC2++ repo directly (necpp), but it evidently doesn’t include Python bindings anymore.
  

Questions

• 
  Is PyNEC currently incompatible with Python ≥ 3.9, or is there a build flag / step I’m missing?
  
  
• 
  Has anyone recently gotten PyNEC to work under WSL Ubuntu?
  
  
• 
  Is there a known workaround (shim module, alternate binding, or pinned Python version)?
  

At the moment my only workaround is to run the nec2++ CLI and parse CSV in Python, which works but isn’t ideal.
