explore_data tutorial instrument_view with issue

[jorobledo]

Hi all,

Was trying out scippneutron and following up with the tutorial 1_exploring-data.html and encountered two small issues which I worked around. I installed scippneutron by pip install scippneutron[all] in a new pyenv on Ubuntu.

• When wanting to visualize instrument with scn.instrument_view() missing pythreejs dependency (installed it manually afterwards).
• Then got an error on the plotting:
  
  which was solved by modifying scene = fig.children[0].canvas.scene to scene = fig.canvas.scene in instrument_view.py.

Then it worked smoothly., but might as well report it.
Nice job btw.!

Thanks!

The second issue was actually fixed in #505. We should make a release...

Concerning the first point, the all extra is a bit misleading. If you want interactive (3d) plots in Jupyter, you need the interactive extra: pip install scippneutron[all, interactive]. I'm going to change this in the docs.

I was waiting for #507 to make a release. @MridulS what's the status there?
