Assertionerror in tutorial

[ghost]

Hi,

I'm trying to emulate this tutorial: https://nbviewer.jupyter.org/github/theislab/diffxpy_tutorials/blob/master/diffxpy_tutorials/test/multiple_tests_per_gene.ipynb

However, as you can even see there, defining the test returns an AssertionError, meaning that you can't then call "test.summary()" or anything else related to the test since it's undefined. How can I fix this? Is the tutorial simply not relevant anymore?

I noticed the same issue actually: @davidsebfischer @Hoeze @ivirshup

It might be useful to have an update here
