Hi Andrea,
The "show()" command only works inside the Jupyter notebook (also known as
the IPython notebook).
You should do "slc.save('/path/to/img.png')" instead, that will save the
SlicePlot to disk as 'img.png'. The reason "show()" works in the example
you linked to is because that part of the documentation is actually a
Jupyter notebook.
More details about save() here:
