Unable to retrieve region factors for PoissonVI model

[duyguk]

Hi! I am unable to retrieve region factors with model.get_region_factors() for PoissonVI models (one trained on my own dataset, another trained on a subset of the tutorial PBMC data). The call instead returns the following error:

AttributeError: 'VAE' object has no attribute 'region_factors'
