SysVI attributes listed in API don't appear in trained model

[danieljrichard]

Hello, I was working through this example for running SysVI:

(https://docs.scvi-tools.org/en/stable/tutorials/notebooks/scrna/sysVI.html)

And tried running get_normalized expression. However, I get this error:
AttributeError: ‘SysVI’ object has no attribute ‘get_normalized_expression’

However, the API indicates this is an attribute:
(https://docs.scvi-tools.org/en/latest/api/reference/scvi.external.SysVI.html#scvi.external.SysVI.get_normalized_expression)

Am I doing something wrong, or do I somehow need to convert this SysVI object to a scvi object?

Any help would be greatly appreciated!

SysVI.setup_anndata(
    adata=adata,
    batch_key="system",
    categorical_covariate_keys=["batch"],
)

model = SysVI(
    adata=adata)
scvi.settings.num_threads = 20
scvi.settings.dl_num_workers = 20

model.train(
    plan_kwargs={
        "kl_weight": 1,
        "z_distance_cycle_weight": 5
        # Add additional parameters, such as number of epochs
    }

normalized_out = model.get_normalized_expression(adata, transform_batch="mouse", library_size = 'latent')

)```

<!-- Put your Error output in this code block (if applicable, else delete the block): -->

```pytb
AttributeError: 'SysVI' object has no attribute 'get_normalized_expression'

Versions:

'1.2.0'

It is not implemented yet, you are correct.
It is in the API because of RNAseqMIXIN inheritance, but the function is not working out of the box.

We will fix it.

Thanks for the update - much appreciated!
In the meantime, might there be any hints/ways to coerce the model into a scvi-like object to access those attributes, or is it more complicated than I'm imagining?
