Description
As far as I can tell from documentation (matplotlib.org/3.2.2/api/_as_gen/matplotlib.pyplot.savefig.html), following should work:
#! /usr/bin/env python3
from sys import stdout
import matplotlib.pyplot as plot
plot.savefig(stdout, format = 'png')
but produces:
Traceback (most recent call last):
File "./bug.py", line 4, in <module>
plot.savefig(stdout, format = 'png')

I'm using /usr/lib64/python3.8/site-packages/matplotlib-3.2.2-py3.8.egg-info from fedora 32. Same thing with at least format=pdf.
