Python script error after PYNQ Z2 upgraded from V2.6 to V3.0

@Luke2020

This is a very old issue commonly found in 2.7 or older days:

While the composite overlay package is stable to use and got to install manually.

Usually if you want any action, use Jupter notebook to open terminal is the best way to make sure it is in the correct venv.

Enjoy~
