ImportError due to pooch dependency in scipy.database module in python/scientific-python.ipynb

[aknierim]

Running the scientific-python notebook yields the following error:

ImportError: Missing optional dependency 'pooch' required for scipy.datasets module. Please use pip or conda to install 'pooch'.

This is due to the optional dependency pooch added in scipy 1.10.0.

Given that we only use it once and only for example data: is there maybe another way to get the data and prevent more packages? Especially if they don't depend on anything else than example data

[aknierim]

I see your point, but given that it is a very small package, I'd argue to just use it.
