This is not backward compatible, for people that use the existing conda packs it'll break.

rather than

import automlx

the suggestion was to do

try:
  import automlx
except ModuleNotFoundError:
  import automl

something like that so older conda packs will continue to work with the refreshed notebooks

The notebook runs fails on existing code with new automlx import. It required code modification in notebook for some features.
