Allows to do this set_activation = dict(activation_fn=torch.nn.Softplus) vae = scvi.model.SCVI(adata, encoder_kwargs=set_activation, decoder_kwargs=set_activation)

Hey, I would also be interested in trying out different activation functions. I guess this PR still isn't in the code base, is that right? Any chance it could be...? :D

Thanks!

I'm happy to get something here in. Let me discuss with @martinkim0. Ideally we would have configs, but this might not be doable.
