Question

I tried running code below using scanpy library but for some reason it reports an error

ModuleNotFoundError: No module named 'igraph'

import numpy as np
import scanpy as sc 
import anndata

adata = anndata.AnnData(np.random.rand(300,300))
sc.tl.pca(adata, n_comps=30)
sc.pp.neighbors(adata, n_neighbors=16)
sc.tl.diffmap(adata, n_comps=50)
sc.tl.louvain(adata, resolution=1)
sc.pl.paga(adata)

Answer 1

您只需要使用命令运行安装 igraph 库

pip install python-igraph
