ipython-notebook layer does not show inline plots

[Eoksni]

Description

ipython-notebook layer does not render inline plots, for example this cell

import matplotlib.pyplot as plt
from numpy import random
%matplotlib inline
def plotnormal():
    return plt.plot (random.randn (1000), random.randn (1000), 'o', alpha=0.3)
plotnormal ()
plt.show()

Reproduction guide 🪲

• Start Emacs
• Login to jupyter ein:notebooklist-login
• Open notebook list ein:notebooklist-open
• Open/create new notebook
• Execute cell

Observed behaviour: 👀 💔

Single . (dot symbol) is shown as output

Expected behaviour: ❤️ 😄

Plot should be shown

Unfortunately I can't reproduce - everything is working on my Windows system.

Try this - put your cursor over the dot and execute C-c C-e.

If that doesn't do the trick can you do the following and post the results:

M-: (require 'ein-dev)
M-x ein:dev-show-sys-info

Thanks.

[Eoksni]

C-c C-e doesnt change anything, still just . character instead of a plot.
M-x ein:dev-show-sys-info

It's probably just spacemacs issue, I was actually intended to post this issue to spacemacs repo, not here :) Tomorrow I will try with emacs -Q and see if an issue persists, then I can be sure if its spacemacs-related or not.

I have the same issue on emacs 25 on Linux Manjaro.
I don't think it has to do with your mac..
ipython works as shell when executed by a pyton file but not in notebook enviornment.
it looks badly formatted too. all the lines including th ' In [2]' are stacked to the left with no indentation and the code that I type appear highlighted as if it is selected by C-..

[marcoleewow]

I am experiencing the same issue, @Eoksni have you found out the cause of this issue?

[Eoksni]

@marcoleewow No, I haven't - but I haven't looked into it too much. I tried with emacs -Q and it wasn't working too, so most likely it is not related to emacs configuration. I guess the problem is with emacs installation itself (I remember Windows Emacs wasn't rendering images untill I installed some additional libs) or something with the python (I wasn't using "pure" python, instead is was from anaconda environment). Or its a bug of this package.

I had the same problem. First I checked that the graphics had really been created by looking into the .ipynb file (with a text editor) and opening it in HTML browser with jupyter notebook. Second (with M-x customize-group RTN ein), I toggled on the variable Ein:Output Area Inlined Images, restarted Emacs etc. and it worked.
