Pyplot's `show()` opens a window with my plot, but `show_with_alt()` doesn't

[adamnovak]

I have a command-line Python script that makes a Matplotlib plot and either saves it to a file or displays it, using the interactive window that Pyplot's show() opens up when running outside a notebook but with access to a windowing system.

If I replace my show() call with show_with_alt(), I don't get a GUI window anymore. Instead, I get this:

/private/home/anovak1/.local/lib/python3.10/site-packages/matplotalt/matplotalt.py:180: UserWarning: FigureCanvasAgg is non-interactive, and thus cannot be shown
  plt.show()

Does show_with_alt() only contemplate being used within a notebook environment?

I'm currently unable to replicate this on my machine. show_with_alt() should work in both notebook and script environments, and calls plt.show() at the end of the function. Could you please attach your code that's getting the error?
