[BUG]: PySR currently incompatible with Python 3.12

[MilesCranmer]

Until the PR at JuliaPy/pyjulia#538 is merged, PySR is currently incompatible with Python 3.12. This is due to a breaking change in the way Python allowed PyJulia to overload the import function (like from julia import SymbolicRegression). It seems to be an easy patch though, luckily.

Also incompatible with 3.11.6

Hi @PaulGersberg,
That looks like a different issue. The 3.12 incompatibility is specifically related to how imports work in PyJulia (which was introduced in 3.12.0, but not earlier).
Cheers,
Miles
