Why does model compression not happen in X-Cube-AI / STM32CubeMX.AI?

[AMk.1]

Hi,

I am trying to deploy the MobileNet NN on a NUCLEO, and I am using X-Cube-AI (7.3) software pack.

When using the keras model (H5) and opting for compression with different settings like "high", "medium", "low", the size of model is not decreased at all. (By size, I mean compression in weights and activations)

Is there any specific reason why the compression is not applied? The logs and analysis report do not mention anything about this.

Thanks,
