Looks like a problem with pyqt5 (Related #236)

I haven't gotten around to upgrade versions yet, but you can try out the pyqt6 fork like this

pip install "git+https://github.com/JoepdeJong/LaTeX-OCR.git@fix/m2-apple-silicon#egg=pix2tex[gui]"

I passed the error, but I am now having issues with some commands. Along with the wait time

Related: https://github.com/huggingface/tokenizers/issues/1036

A fix would be to upgrade the tokenizers package to 0.13.0

pip install -U tokenizers==0.13.0

This will print an error along the lines

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. pix2tex 0.0.29 requires tokenizers==0.12.1, but you have tokenizers 0.13.0 which is incompatible.

From an initial test it looks fine but more testing is required.

[lukas-blecher]

I've added everything to the main branch, including tokenizers version.

Please try pip install -U pix2tex[gui]

I met this bug. I try pip install pyqt6 failed with sipbuild.pyproject.PyProjectOptionException Error. I fix this by install pyqt6-tools manually. pip install pyqt6-tools. then install pyqt6 will success without exception.
