Hi Kati and Alex
Looking for the solution of the error that Alex mentioned posts ago I found this forum.
I have the same issue as @alextintin007, the same error.
I run the following tutorial on my MacBook M1 Pro
https://cms-opendata-workshop.github.io/workshop2021-lesson-docker/
and at the part Test and validate it says that we have to run the python script. I modified it with the text that says and it throw out the error.
It seems that @kati is working on it. Thanks a lot!
@alextintin007 have you find the solution? Thanks for creating this forum!
