Here is the reproducible example below: ```python import numpy as np import scanpy as sc adata = sc.datasets.pbmc68k_reduced() sc.pp.neighbors(adata, method="gauss") sc.tl.leiden(adata, resolution=0.5, key_added="leiden_0_5") sc.tl.diffmap(adata, n_comps=10) adata.uns["iroot"] = np.flatnonzero(adata.obs["leiden_0_5"] == "0")[0]...
