I had not set labels\_key when first using. `sca.models.SCVI.setup_anndata(source_adata,batch_key=condition_key)`. After annotated all cells, how could I create a scANVI model with the first scVI model? Or, should I just try to train a new scVI model with ‘labels\_key’.

Hi, we have an example of that in [this](https://docs.scvi-tools.org/en/stable/tutorials/notebooks/scrna/harmonization.html) tutorial, where you can set a new labels key for scANVI after training with scVI.
