ERROR when "connecting" to viewer

[jortiz12]

Dear community

I´m trying to replicate the examples imexam_ds9_example.ipynb or imexam_ginga_example.ipynb but I'm having errors when executing either of these two commands.

a=imexam.connect()

a=imexam.connect(viewer='ginga')

The corresponding errors are

, and,

, respectively.

The issue may be due to the fact that I'm trying to run these notebooks in Google Colab, as opposed to in a local (ie in my computer) Jupyter session.

Any workaround would be highly appreciated. It may be due to the fact that I'm running the notebook in Google's platform as opposed to in a "local" (ie in my computer) Jupyter server.

Kind Regards
Jose
