failing to import util.selector

[epeter-]

i don't know what happened.
my code up to now was like:
import ifcopenshell
import ifcopenshell.api
import ifcopenshell.util
from ifcopenshell.util.selector import Selector

i installed a new system (python) and now i get an error message:
Module not found error: no module named 'unicodedata' in module ........ ifcopenshell\util\selector.py' line 20 in module

what am i missing. till recently ifcopenhell ran in my system without 'unicodedata'
remark: unicodedata2 is installed as pyd module

@epeter-

Can you please copy here the full traceback?

ifcopenshell\util\selector.py' line 20 in module

Is it failing during lark import? What version of lark do you have?

[epeter-]

lark version is 1.1.9.

[epeter-]

unicodedata version is unicodedata2-15.1.0.

@epeter-

It looks like you previously used older version of lark and now it's requiring unicodedata - lark-parser/lark@74c94bb

I'm not sure if unicodedata2 helps if unicodedata module is missing.

Do you have unicodedata.pyd module somewhere in your system? I have it in Python 3.11\DLLs\unicodedata.pyd. If it's missing maybe it's something about the python installation? Or if it's present then it's something about the system paths since python couldn't locate it.

[epeter-]

i do not have the unicodedata.pyd on the system, and cannot find it on the net. all i have is unicodedata2.pyd

You can try to reinstall python or try to use some other version of lark.

@Andrej730 thank you for guiding me in the right direction!
as you suggested lark is now 1.1.9 as current version. when installing lark 1.1.8 the code worked again.
