python seaborn to reset back to the matplotlib

Question

I'm using seaborn version o.4 and matplotlib version 1.42 I have a chart displays both line and marker through simple plot command eg.

plt.plot([1,5,3,8,4],'-bo');

Due to a potential bug (https://github.com/mwaskom/seaborn/issues/344), after import seaborn, same code shows line only without marker.

import seaborn as sb 
plt.plot([1,5,3,8,4],'-bo');

So my question is: after import seaborn, Is there a way to reset all the parameters back to original?

Answer 1

To refresh Matplotlib's configuration side effects often encountered with Seaborn:

import matplotlib as mpl
import matplotlib.pyplot as plt
import seaborn.apionly as sns

Run this:

import importlib
importlib.reload(mpl); importlib.reload(plt); importlib.reload(sns)

For old Python2 code:

import imp
imp.reload(mpl); imp.reload(plt); imp.reload(sns)

Note: None of the following correctly restores the state of matplotlib:

• sns.reset_orig()
• sns.reset_defaults()
• mpl.rcParams.update(mpl.rcParamsDefault)

Answer 2

One can simply call the seaborn.set() function, with no function parameters, see [seaborn tutorial][1].

Answer 3

You can save the rcParams you want, before changing the style with seaborn (note that seaborn no longer changes the rcParams upon import):

import matplotlib as mpl

my_params = mpl.rcParams

# apply some change to the rcparams here

mpl.rcParams.update(my_params)

Note that both these

mpl.rcParams.update(mpl.rcParamsOrig)
mpl.rcParams.update(mpl.rcParamsDefault)

restores almost all rcParams to their default value. The few that will be different can easily be viewed by (I ran this in a Jupyter Notebook):

# Differences between current params and `Default`
for key in mpl.rcParamsDefault:
    if not mpl.rcParamsDefault[key] == mpl.rcParams[key]:
        print(key, mpl.rcParamsDefault[key], mpl.rcParams[key])

## backend agg module://ipykernel.pylab.backend_inline
## figure.dpi 100.0 72.0
## figure.edgecolor w (1, 1, 1, 0)
## figure.facecolor w (1, 1, 1, 0)
## figure.figsize [6.4, 4.8] [6.0, 4.0]
## figure.subplot.bottom 0.11 0.125

and

# Differences between `Default` and `Orig`
for key in mpl.rcParamsDefault:
    if not mpl.rcParamsDefault[key] == mpl.rcParamsOrig[key]:
        print(key, mpl.rcParamsDefault[key], mpl.rcParamsOrig[key])

Answer 4

Yes, call seaborn.reset_orig.
