Looks like incorrect place for definition of variable.
May be better define it in src/nncf/definitions.py ?
And for users add note in docstring of Dataset that it can be use stateful models

Changes
Added
nncf.definitions.NNCF_DATASET_RESET_STATE_KEYconstant to specify when to reset model state. This constant is used by OpenVINO backend to control resetting of internal model state between model inferences. This key can be added to a dataset sample input dictionary with eitherTrueorFalsevalue. WithTruevalue, the model state will be reset before inference on the corresponding sample, and withFalsethe state will not be reset.For an example of usage please see huggingface/optimum-intel#1505.
Reason for changes
Without this logic static quantization quality of stateful Whisper models is poor because a state of a stateful model must be cleared with the same schedule as it is done during calibration input data collection.
