ValueError: zero-size array to reduction operation minimum which has no identity

[Isabelle-C]

Hello! I am running the code used in the tutorial on my scRNA-seq data and everything was fine until I ran this line: st.plot_dimension_reduction(adata,color=['label','n_genes'],show_graph=False,show_text=False)

It gives me the following error ValueError: zero-size array to reduction operation minimum which has no identity

If I only put 'n_genes' in the color, I am able to produce a figure. What can this issue potentially be?

I am not very familiar with this tool, but this seems so cool! Please let me know if more information is needed. Thank you!
