[Python-modules-team] Bug#847225: (no subject)

[Gordon Ball]

Thanks for reporting this. It's good to know someone was looking forward
to the package.

I have just run the example you provided on two different systems
unfortunately without seeing what you saw - firefox/sid and
chromium/yakkety. (You didn't specify if this was python or python3, but
I would be surprised if that made a difference).

The ipywidgets warning should be unrelated. (Incidentially, ipywidgets
is now also packaged, but the example you give shouldn't be affected by
not having it installed).

Things I can think of:

 * are all the libjs packages up-to-date? (it is possible some
dependencies should be more tightly versioned)
 * is there any javascript errors in the web console, or 404 errors in
the network console? (expect to see a single 404 extension.js, since
ipykernel doesn't provide any javascript extension)
 * can you use the firefox/chromium web inspector to identify the
element appearing as a black square? (perhaps a missing image file?)
