Error when importing libcombine from python

[Yannik Schälte]

Upon import libcombine from python, I get the below error. Seems to happen on python3.8, not on 3.6 (used a clean anaconda installation). Further, pip install python-libcombine, gives me version 0.2.1, though 0.2.3 should be the latest? 0.2.3_1 is available too.

>>> import libcombine

During handling of the above exception, another exception occurred:

error is indeed gone when I install pip install python-libcombine==0.2.3_1 (giving 0.2.3)

[Frank Bergmann]

i'll re-release a newer version, that should take care of the issue. Sorry for the trouble, unfortunately i won't get to it before monday as i'm traveling

[Yannik Schälte]

no problem, works for us. thanks for the fast reply!

[Jonathan Karr]

I've seen the same issue. It appears to be related to Python 3.8.

[Frank Bergmann]

this should now been resolved for version 0.2.6.

[Yannik Schälte]

thanks, it seems resolved!
