latexocr: DLL load failed while importing QtCore

[MartinNiederl]

I created a new conda env using:

conda create --name latex_ocr python=3.10
conda activate latex_ocr
conda install pytorch pytorch-cuda=11.8 -c pytorch -c nvidia
pip install "pix2tex[gui]"

Getting error:

Traceback (most recent call last):

ImportError: DLL load failed while importing QtCore: The specified procedure could not be found.

Also tried installing versions 6.5.1 and 6.5.2 of PyQt based on this https://github.com/lukas-blecher/LaTeX-OCR/issues/257#issuecomment-1651686937 but the error message is still the same.

HI @MartinNiederl I had the same problem and I solved it as follows

I removed all packages that have different versions and installed only versions 6.5.1 for them all

you can do so by implementing these codes

pip uninstall -y PyQt6 PyQt6-Qt6 PyQt6-sip PyQt6-WebEngine PyQt6-WebEngine-Qt6

pip uninstall -y PySide6 PySide6-Addons PySide6-Essential shiboken6

pip install PyQt6==6.5.1 PyQt6-Qt6==6.5.1 PyQt6-WebEngine-Qt6==6.5.1 PyQt6-WebEngine

pip install PySide6-Essentials==6.5.1 PySide6==6.5.1 PySide6-Addons==6.5.1 shiboken6==6.5.1

after that install the latest version as recommended by the author

pip install "git+https://github.com/lukas-blecher/LaTeX-OCR.git#egg=pix2tex[gui]"

It works for me now
