Error happens whenever i want to use wplot().  
Im using miniconda3 on windows 10.

Also i would like to add i could make visan launch properly only on environment with python 3.6 from stcorp channel.  
With other environment like python 3.7 or 3.8 visan wont launch for some reason, either from stcorp channel or forge channel no idea why tho.  
Tried on 2 different pc with same result both with windows 10.

i found workaround, i’ve asked friend to send me compilated 2-3months old environment from anaconda and its working via terminal.  
I don’t know why and how but hey im not complaining after 2 weeks of struggle.
