Area of Concern

Describe the bug I call object detection API with custom model 2 time with +120sec between and the second time, the model used wasn't YOLO but default model.

API called: http://XXX:32168/v1/vision/custom/YOLOv5

server log output: Response rec'd from Object Detection (Coral) command 'custom' (...6e9f4a) ['Found car, person, car'] took 280ms 11:48:39:objectdetection_coral_adapter.py: WARNING:root:No work in 120.0 seconds, watchdog shutting down TPUs. 11:49:47:Response rec'd from Object Detection (Coral) command 'custom' (...8c1757) ['No objects found'] took 2751ms 11:50:02:objectdetection_coral_adapter.py: Object Detection (Coral) started. 11:50:02:objectdetection_coral_adapter.py: no TPU interpreters: Falling back to CPU detection 11:50:02:objectdetection_coral_adapter.py: No interpreter found. Recreating. 11:50:02:objectdetection_coral_adapter.py: Model change detected. Forcing model reload. 11:50:02:objectdetection_coral_adapter.py: Timeout connecting to the server

As you can see, first time the model detect person car etc... and second time (same query) nothing found and the model was changed.

Expected behavior Keep the model configured on the start of the module.

Your System (please complete the following information):
