compatibility with seaborn and/or Notebook-5.2.0 and/or %matplotlib directive ?

[stonebig]

On a Notebook-5.2.0, If I do this:

import ipympl
import matplotlib.pyplot as plt2

plt2.plot([0, 1, 2, 2])
plt2.show()

then next cell, I have to put a %matpollib inline to get my seaborn image, otherwise nothing is displayed:

%matplotlib inline
# Seaborn
# for more examples, see http://stanford.edu/~mwaskom/software/seaborn/examples/index.html
import seaborn as sns
sns.set()
df = sns.load_dataset("iris")
sns.pairplot(df, hue="species", size=1.5)

is it normal ?

same if I stay on plt instead of plt2:

if I do %matplotlib inline in first cell, I get some bad words:

ah, on jupyterlab side:

jupyter labextension install matplotlib-jupyter
...
...
...
npm ERR! 404 Registry returned 404 for GET on https://registry.npmjs.org/matplotlib-jupyter
npm ERR! 404
npm ERR! 404  'matplotlib-jupyter' is not in the npm registry.

@stonebig no need for %matplotlib inline. Just an extra call to plt.show() after your seaborn command does the job.

I updated the README, it should be jupyter labextension install jupyter-matplotlib.

Closing since both questions were resolved.
