The point I was trying to make is that if you have actuators running MISRA C that are going to be driven by something written in Tensorflow, does it still makes sense to have a requirement to use MISRA C in the first place for the low level part ?

I'd be very wary of using complex SOUP like TensorFlow, even if brought under my quality system. I think a good answer here is that once one goes under design control the subset of functionality needed should be implemented in-house under the organization's SDLC.

Of course these things are meant to be used (1) to train the system, (2) as a player in the prototype. Exactly like in the old school ML-based systems: you train in Matlab or CudaConvNet, and then you load the trained classifier into the custom-made player highly tuned to your hardware and problem domain.

Most certainly - safety should be guaranteed at the lowest level, even if Tensorflow gets borked.

Think of it as a failure cascade - if Tensorflow breaks, the car can safely stop. If the low level stuff breaks, the car may not be able to stop (or go).
