metaclass conflict

[deligkarisk]

Hi,

I have managed to successfully install tierpsy-tracker in Ubuntu 22.04. I am trying to figure out how to use it with some sample videos we have.

However, when I click "Start" to run the batch processing I see the following output. I was wondering if this is a bug or perhaps something I set-up incorrectly.

Any feedback would be appreciated.

Could you send me your parameters file and video please. (weheliye@ic.ac.uk)

Thank you @WeheliyeHashi for the feedback.

The issue was caused by some libraries incompatibility.

I re-did the installation with python 3.6 and the associated requirements file, and it now works just fine.
