Unable to visualize data in test code about pinns HOT 3 CLOSED

The visualization of text uses LaTex. Did you have it installed?
If it doesn't work, you can try to remove the Tex rendering.

from pinns.

The latex rendering configuration can be found in line 22-23 at Utilities/plotting.py. Remove these two lines:

    "pgf.texsystem": "pdflatex",        # change this if using xetex or lautex
    "text.usetex": True,                # use LaTeX to write all text

from pinns.

@michaeljehan If you use version 3.1.2 of matplotlib the problem disappears.

pip install matplotlib==3.1.2

from pinns.
