Why isn't it possible to run solo when there are categorical_covariate_keys?

[alexlenail]

I have a large experiment in which multiple mice were each separately sequenced in multiple 10X channels. So each mouse has multiple channels. I created by model with:

scvi.model.SCVI.setup_anndata(
    adata,
    batch_key='channel',
    categorical_covariate_keys=["Mouse"],
)

And now I want to remove doublets, but just found out

ValueError: Initializing a SOLO model from SCVI with registered categorical covariates is currently unsupported.

Should I leave out the "Mouse" covariate? I don't understand what I'm supposed to do here.
