Does not work in Google Colab

[AlexeyG]

nglview does not seem to work in a Google colaboratory. Issuing the below commands (after the package was successfully installed via pip install) just crashes the runtime.

import nglview
import ipywidgets
nglview.show_pdbid('3pqr')

hi, I am not sure if codelab supports 3rd party software like nglview. Does that lab work with ipywidgets-based bqplot or ipyvolume or something else? The issue here is that pip install nglview is not sufficient to make nglview work. User normally need to "activate" the javascript code via jupyter-nbextension enable nglview --py --sys-prefix (don't ask me why because I don't know why we really need that :D). That step should be done before opening the notebook.

It seems that google people need to add nglview by themself:

• Add Ipywidgets support  googlecolab/colabtools#60 (comment)
• Support installation of custom widgets. googlecolab/colabtools#498

@AlexeyG Runtime says "Busy", and the little icon keeps spinning forever.
Mine is using conda to install nglview.
!conda install -y --prefix /usr/local nglview -c conda-forge
I think Colab doesn't support a lot of packages. Anyways, thank you for your issue report. Otherwise I have to wait, like, forever.

I go ahead closing this case since it's out of our control. Thanks for asking.
