Hi!
I would like to know how to use the on-the-fly model in python apps!
I see we can use it on the sample apps!

What is “on-the-fly” model?

On-the-fly model update (Engine file only)- Feature!

We have the c/c++ implementation of OTA. On the Fly Model Update — DeepStream documentation 6.4 documentation

The deepstream-test5-app is open source. You can refer to the implementation.
