Error plotting velocity graph

[bapoorva]

Hi,

I'm running scVelo and when I tried to plot the velocity graph, I'm getting this error-

 scv.pl.velocity_embedding_stream(adata, basis="umap", color="seurat_clusters")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    return object.__getattribute__(self, name)
AttributeError: 'Series' object has no attribute 'categories'

Not sure how to fix it. Also, how do i save plots command line?

Thanks

Seems like a duplicate of #811.
