Question/Issue:
I wanna run my model locally on my Raspberry Pi 3B and a Raspberry Pi Camera Module V2. When I run edge-impulse-linux or edge-impulse-linux-runner the camera is detected and it works perfectly fine. However, when I try to run the classify.py example it returns this:
MODEL: /home/pi/linux-sdk-python/examples/image/models/FOMO-int8.eim
Loaded runner for "Benjamin / Real-Time Object Tracking for Autonomous UAVs"
