[Detector Support]: Training State classification model fails.

[GregsyS]

Describe the problem you are having

I am trying to train a state classification for a gate being open or closed. I get the error "Model training failed. Check the logs" after a second or so. These state "Illegal instruction".

I've checked my CPU and it supports AVX2. (i3 11110U https://www.intel.com/content/www/us/en/products/sku/196451/intel-core-i310110u-processor-4m-cache-up-to-4-10-ghz/specifications.html ).

8GB RAM installed.

I have 2 Coral EdgeTPUs, 1 USB and the other a single chip M.2.

I had read that, that's why I checked my CPU specs. I'm running Frigate as an Addon in Home Assistant OS so no virtualisation options to change.

[GregsyS]

Anyone any suggestions to try?
