Create Gradio-based GUI

[MilesCranmer]

Seems like it would be useful to have a GUI for PySR as some people would like to use it but don’t have much programming experience. It’s also a bit nicer on the interactivity side.

This PR creates a Gradio-based GUI for PySR and stores it in the main repo. Pushing this repo to HuggingFace will result in a working space:

https://huggingface.co/spaces/MilesCranmer/PySR

This can even be executed in the web browser.

TODO:

• Add the virtualenv to PATH so regular Python calls work
• Turn off the progress visual in loading elements in gradio
• Have a reader process which can evaluate predictions of the model
• Add more options to the GUI
• Have the GUI also have a button which generates the Python code corresponding to if you had run it with a script
• Have the process be persistent so Julia doesn’t need to recompile
• Add action to sync PySR with hugging face
• Put gui within normal PySR code, but with lazy loading of matplotlib and gradio. Add a gui command to the CLI. (Cancelled)
  • Would be nice, but it requires loading PySR when starting the GUI which is incompatible with gradio.
• Refactor to be object-oriented
• Do some manual tests where we spam click the buttons and verify correct behaviour
