Issue with pyplot

Hi,
Have a problem that is driving me nuts, and have narrowed it down to pyplot,
and anything depending on pyplot.

This command works fine:
import matplotlib as mpl

But when I run
import matplotlib.pyplot as plt

The python icon in docks starts jumping up and down and I get:
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (preact.min.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (preact-compat.min.js.map, line 0)
[Error] Failed to load resource: the server responded with a status of 404
(Not Found) (index.js.map, line 0)

Running Python 3.7, Matplotlib 3.0 on a Mac OS High Sierra, and all worked
fine up till just recently

Any ideas anyone?

It looks like you might have things configured to default to a different
backend than normal. Are you running things inside of a notebook? It
looks like it's trying to run one of the web-based backends by default, and
that backend can't set things up correctly.

What happens if you do:

python -c "import matplotlib; matplotlib.use('tkagg'); import
matplotlib.pyplot as plt"

Or equivalently, try doing:

import matplotlib
matplotlib.use('tkagg')
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.plot(range(10))
plt.show()

If these type of examples work, have a look at which backend you have
things set up to use:
https://matplotlib.org/faq/usage_faq.html#what-is-a-backend.

Hope that helps,
-Joe

Thanks Joe!

Changing the backend from ?macosx" to ?tkagg? had no real impact - just that little rocket now bouncing closer to the center of the dock.
The only recent, i.e. potentially relevant update I have made is updating to Matplotlib to 3.0

It seems like the ?missing? json-fies, generating a 404 GET when I run Jupyter, are related to scripting

Thanks,
Ulf

There are some bugfixes in master and slated for v3.0.1 (soon-ish) that may
be relevant for your situation. Could you try installing from the master
branch?

Just installed v3.0.1 and indeed, this appears to have solved my issue. No bouncing little rockets and no ?Python (not responding)" from the Activity Monitor
