This is a known issue: https://github.com/yt-project/yt/issues/2887

it is fixed on the master branch. Since you are using yt 3.6, you can fix this by downgrading matplotlib from 3.3 to 3.2, or you can try installing the latest version from github.

Hello,

I was interested in trying yt as a visualization tool but when installing on Ubuntu the errors mention:

import matplotlib._png as _png ModuleNotFoundError: No module named 'matplotlib._png'

I attached the yt_install.log. Please advise

Sincerely,
