Notebook broke due to dependency problem

[sporst]

Hi,

the linked example notebook broke (regardless of whether it's executed on Binder or Colab) with the following dependency problem:

There are some problems showing when initially executing the first cell. When executing the second cell afterwards I get this:

ContextualVersionConflict: (scipy 1.4.1 (/usr/local/lib/python3.7/dist-packages), Requirement.parse('scipy<2.0,>=1.6'), {'vpype'})

As a quick fix for now you can use Kaggle notebooks, their env seems to be OK to run these dependencies.
