Binder "Getting Started" fails when loading "machine_learning/CL1.hdf5"

[csbrown]

The "machine learning" folder seems to be missing. I've looked around the repo for this file, and don't see it anywhere. I can fix this if anybody knows where the file is.

To download it, go to the end of the notebook and execute the relevant cell. That's indeed not very clear...

Indeed, it is clear in the 2_SVD_and_BSS.ipynb notebook, but not the 1_Getting_Started.ipynb!

Just stumbled across the same. Can't we run at least the Getting_Started notebook with a dataset that is included in the repo? Otherwise we should put the cell for downloading the file at the right position.

Instead of continuing with this type of data, we should use pooch instead, so that we can import data easily from hyperspy.dataset in the notebook demos as scikit-image does.
