gui bug with python 3.13

[fwhotto]

"ModuleNotFoundError: No module named 'typing.io'; 'typing' is not a package'" occurs because Python 3.13 removed typing.io and typing.re as submodules of the typing module.

Installing on python 3.12 solved the issue.

I also have the same issue using Python 3.13.2

I have tracked down the problem. The issue is that pix2tex[gui] requires latex2sympy2 which requires antlr4-python3-runtime==4.7.2.

As can be seen in issue #2611, antlr4 was the reason for this bug, but it was fixed in #3067 and in antlr4 4.9.2.

A workaround could be to manually update antlr4 to a version >=4.9.2:

pip install antlr4-python3-runtime==4.9.2
