KeyError: 'setup_method_name'

Hi, thank you for the scVI tools.

I am trying to do label transfer as mentioned here:

I am getting following error with new conda environment and pip installation of scarches.

May I know how this can be resolved? Many thanks in advance!

Hi, we can't provide support for scArches use of our models. It's better to ask their developers for help. You might want to check our tutorial for the HLCA using Arches mapping: https://docs.scvi-tools.org/en/latest/tutorials/notebooks/scrna/query_hlca_knn.html. Please update if this tutorial doesn't work.
