Issue loading stlearn

[KarlKaise]

Hello, while trying to run the jupyternotebook for slideseq (https://stlearn.readthedocs.io/en/latest/tutorials/Read_slideseq.html) I encountered following error message (See below), while executing the first step of the notebook:
import stlearn as st
import warnings
warnings.filterwarnings('ignore')

Would be grateful for any advice :)

Thanks a lot

Can you check the version of scanpy?
I think the first solution is to upgrade the version of scanpy:

pip install -U scanpy
