Python problem with extensions in virtual enviroment

December 4, 2021

I am using python 3.7.5 version, however I downloaded 3.6 version for specific project and created virtual enviroment, installed required extensions (numpy, matplotlib…). However when I try to run python script, there comes a lot of errors related to extensions. The code worked flawlessly with 3.7 version of python. Any thoughts what can be wrong?
