Followed the directions to install. Can't even run it -h.

Hi @magoldsm
Could you run pip list and paste the output. I think you might have conflicting qt versions.

Thanks,

Hi @magoldsm
Try deleting pyside. Also maybe reinstalling the pipeline_graph since there is something clearly wrong with the installation as well. Maybe install it from source is pypi wheels fail.

Thanks,
Jaka

Here's how I started from (almost) scratch:

Created a new directory Retry
cd Retry; python3 -m venv venv
pip install depthai
pip install pipeline_graph
pip install PySide2

Same crash.

So, I removed PySide2 and installed PyQt5. Now the error was a missing import of distutils. Sadly, that is no longer included in Python 3.13. So, I also pip install setuptools. No more Python crash, but…

Hi @magoldsm
I think you are missing PyQT from the new environment. pip install pyqt5. Also maybe using a different python3 version would not be a bad idea since many packages are probably missing in the new version.

Thanks,
Jaka

Just stumbled over this entry. I had a problem with the pipeline_graph and downgraded to depthai version 2.22.0.

Hopefully it helps (:

@lasse
Depthai version (newer versions) should have no effect on pipeline graph. 2.25.1 works fine for me. Worth giving it a shot incase there might be some other underlying issue.

Thanks
Jaka
