object_detector failure with darknet

[csuther28]

I get the following failure once viseron started up in docker:

The following is my config:

Any idea what I'm doing wrong?

The motion recording is working great though.

From this I gather that the OBJECT DETECTOR is working and detected a person within the area.
But still with the issue 'Failed to retrieve result for object_detector'

Hmm strange, seems that inference is too slow.
Is your CPU maxed out while Viseron is running?

[csuther28]

When I started off, all seems ok...except for the mentioned error alert....at some time did I detect a slowness on server, on closer look, the CPUs were maxed out...I then disabled the object_detector to run continues without motion detector...after this did CPU normalize.......but this alert still popping up.

Does it get any better if you set fps: 1 for the object_detector?
