Error in graph(milo_graph) : 'edges' must be numeric or character

[YubinXie]

I am running the Python scanpy notebook for MILO and got some error in the follwing codes：

%%R -i knn_adjacency
milo_graph <- buildFromAdjacency(knn_adjacency, k=20, is.binary=TRUE)
graph(milo) <- graph(milo_graph)

It says:

Error in graph(milo_graph) : 'edges' must be numeric or character

I noticed that this part is replaced by the following codes. Maybe it is good to remove it from the notebook.
