Is It Possible to Implement Neural Network Compression Framework (NNCF) without Retraining the Model?

Inquired about the possibility to load a pre-trained model and apply NNCF optimization without the need to retrain the model.

The model must be retrained in order to use the NNCF. Refer to Introducing a Training Add-on for OpenVINO toolkit: Neural Network Compression Framework, for the steps to implement the NNCF optimization methods using supported training samples as well as through integration into the custom training code.

The training samples are available at this GitHub* repository.
