Can't load saved yoloV2 network in standalone Matlab app 2021a

Hello,

I have trained yoloV2 detector network and saved it (ver 2021a). I want to load it in a standalone Matlab app (generated in 2021a), but I am getting a warning and then error:

Warning: Variable 'detector' originally saved as a yolov2ObjectDetector cannot be instantiated as an object and will be read as a uint32

Error: Unrecognized function or variable 'detect'

I am able to load the network inside Matlab itself, but no in Matlab standalone app.

I am working in Matlab 2021a

When I was woring in 2020b everything was normal.

Thank you.

See the Tip in the "Fixing Callback Problems: Missing Functions" section of this documentation page. Use the %#function pragma to tell MATLAB to include the class definition yolov2ObjectDetector in your application.
