Matplotlib does not find basic fonts

I am trying to use Computer Modern (i.e. the standard LaTeX font) in my pyplot figures, however, I get the error

findfont: Font family ['serif'] not found. Falling back to DejaVu Sans.

All I do is:

from matplotlib import rc

rc('text', usetex=True)
rc('font', **{'family': 'serif', 'serif': ['Computer Modern']})

I have also found this thread which dealt with the same issue, however, I cannot install the packages mentioned in the answer there because I am not an admin on the machine I am using. Deleting the matplotlib cache did not help, either. I have located the font, though:

~/.local/lib/python3.6/site-packages/matplotlib/mpl-data/fonts/

which has the subfolders afm and ttf (and another one), and within both of them, I find files like

cmr10.afm

or

cmr10.ttf

so the fonts are actually installed on the computer. The fontlist-v330.json file links to

"fname": "fonts/afm/cmr10.afm"

for Computer Modern. I have tried manually changing this to the ttf file, and I have also tried giving it the full path, but to no avail. At this point, I am at a loss for ideas. How can I solve this issue?

All you need to do should be using the actual name of the font file:

from matplotlib import rc

rc('text', usetex=True)
rc('font', **{'family': 'serif', 'serif': ['cmr10']})
