Spacemacs org-mode python session plotting problem

Question

I have been using org-mode with R in Spacemacs for a while now with no issue.

I'm moving my workflow from R to Python.

Jupyter notebooks (EIN) works great, but I prefer org-mode:

Normal (non-plot) blocks work well enough, but Emacs hangs when I try to plot using sessions (I can get it to plot if I don't use sessions).

I get a message that says, executing Python code block... that remains until I escape with C-g.

Here is an example of a function that won't print:

#+BEGIN_SRC python :session *Python*
import glob
from pandas import DataFrame, Series
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from pandas.plotting import register_matplotlib_converters
register_matplotlib_converters()
import seaborn as sns
plt.rcParams["figure.figsize"] = (15, 10)
sns.set()
#+END_SRC

#+BEGIN_SRC python :session *Python* :results output drawer
units.pivot_table('A', 'B', 'C', aggfunc=len).fillna(0).plot()
fig=plt.figure(figsize=(6,4))
plt.savefig('test.png')
'test.png'
#+END_SRC

I really want to use org-mode instead of notebooks. Any idea what I need to correct to make it work?

Try usimng ipython blocks instead of python (#+BEGIN_SRC ipython) and add the following line to your first source block:

%matplotlib inline

Note - I'm not sure if this will work with Spacemacs, but it is what scimax is all about. I used Spacemacs for about 6 months for python and jupyter notebooks before I switched to scimax for org-mode and never looked back.
