I'm sorry - I don't know what this relates to.
Is that the klayout module on PyPI? If so, there is no trouble with importing klayout.

I just had the same issue.
The reason for my case was, that I created a conda-package for linux, but installed it under windows.

I don't have conda, but I tried with the standard Python distribution on Windows 11. No issues.

The trouble you have usually originates from DLL dependency issues. Auditwheel should prevent that, so I think there is a problem on your side. These problems are difficult to debug. ProcMon is my friend in these cases.

Hello,
I have a similar problem:

----> 7 import klayout.lay as klay
8 import klayout.db as kdb
10 layout = kdb.Layout()

File ~\AppData\Local\Programs\Python\Python314\Lib\site-packages\klayout_init_.py:2
----> 2 from .tl import version

File ~\AppData\Local\Programs\Python\Python314\Lib\site-packages\klayout\tl_init_.py:2
----> 2 from ..tlcore import all
3 from ..tlcore import *

ModuleNotFoundError: No module named 'klayout.tlcore'

I installed klayout with pip (pip install klayout), and I use Windows. As I am not an expert of python, I don't know how to solve it.
