Can't open GUI - Error: _init_pyside_extension is not defined

[stowerslab]

Hello,

When installing deepethogram I encountered one of the issues stated in the common installation problems section. The error name is '_init_pyside_extension is not defined'. I followed the steps mentioned there: pip uninstall pyside2, conda remove pyside2, pip uninstall deepethogram, pip install deepethogram. However, after doing that, I'm getting the same error when trying to start the GUI. Any idea of how can this be solved? Thank you!

Hi there, what OS are you working on?

If you're comfortable with trying Docker, I just pushed some docker images. That should give a 100% reproducible environment, which should fix your issues.

Hi @stowerslab, this suggestion from a previous comment helped me resolve this issue on Windows in case that's your os:

pip uninstall PySide2

conda uninstall pyside2

conda install -c conda-forge pyside2

Just coming here to confim I get the same error after following the installation instructions:

conda create --name deg python=3.7
conda activate deg
conda install -c conda-forge pyside2==5.13.2
pip install deepethogram

and running the following solves it

pip uninstall PySide2
conda uninstall pyside2
conda install -c conda-forge pyside2

My system is Windows 11, but I can confirm that an identical error happens on Windows 10

@axellenoesen I get a similar error upon launching deepethogram

And it's solved with the same commands you shared, thanks! :D
