This line relies on you having renamed your clusters as indicated in the notebook. You can check what your cluster names are via adata.obs['louvain_r0.5_entero_sub'].value_counts(). The output of that will tell you what your clusters are called (and how many cells are in each cluster). You can then rename the 'Enterocyte matrue' string to the particular cluster you'd like to subcluster.
