I've tried using ipyaladin in a jupyter notebook with

!pip install ipyaladin !jupyter nbextension enable --py widgetsnbextension !jupyter nbextension enable --py --sys-prefix ipyaladin

but the last line doesn't work in Google Colab. Is there an alternative to this code?

Good question, I don't know Google Colab at all, but I'm going to investigate. Keep tuned. Thank you for your interest!

It could be very useful to fix it. I copy the output from Colaboratory:

!python --version Python 3.7.10

!pip install ipyaladin !jupyter nbextension enable --py widgetsnbextension !jupyter nbextension enable --py --sys-prefix ipyaladin

In case it helps, I solved the part of jupyter looking for extensions in the "wrong place" (python2.7/dist-packages) the following way:

get versions >6 tornado and the client

!pip install tornado --upgrade !pip install jupyter-client --upgrade

!pip install https://github.com/ipython-contrib/jupyter_contrib_nbextensions/tarball/master !jupyter contrib nbextension install --user

!pip install ipyaladin

!jupyter nbextension enable --py widgetsnbextension !jupyter nbextension enable --py --sys-prefix ipyaladin

With that I got no errors, and if I list the nbextensions, ipyaladin appears as "OK" (validated)

Unfortunately when I call aladin, I still do not get the widget :-(

bmatthieu3 commented 1 year ago

From the new version 0.1.11, ipyaladin does not seem to need these 2 lines anymore:

!jupyter nbextension enable --py widgetsnbextension !jupyter nbextension enable --py --sys-prefix ipyaladin

It might be interesting to retest on your side with ipyaladin upgraded. Let me know what is the outcome, thanks very much

ggreco77 commented 1 year ago

I tested the new version in Google Colab here. Although there is support from Google Colab for the Third-party Jupyter widgets; the ipyladin widgets are not displayed. thanks!

bmatthieu3 commented 1 year ago

Hi @ggreco77 @ManonMarchand I found that external jupyter widgets (such as ipyaladin) from ipywidgets need a little snippet of code after importing ipyaladin.

from google.colab import output
output.enable_custom_widget_manager()

By doing this, it works for me:

ggreco77 commented 1 year ago

Got it; it works perfectly. thanks!

ManonMarchand commented 1 year ago

Yup, perfect here too. I guess you can close this issue :)

Can I use ipyaladin in Google Colab? #23
