Problems getting object detection work

[zmki_jego]

Hello, I have installed zoneminder and event sever completely from scratch and according to official docs, i.e. did everything as described there. But for whatever reason and all that I‘ve tried I cannot get object detection to work in zoneminder. Opencv is properly installed and up and running. Doing object detection outside zoneminder with some sample scripts downloaded from the internet also works fine. But for whatever reason not yet in zoneminder. Could you please help me out solving it. That would be great. At the moment when I try object detection manually on the command line for a certain zoneminder event I get the following output, so something seems to be wrong with my installation?
Thanks a lot for your support.
