an error in failing to save stream figures aftering installing some packages like "mpi4py petsc petsc4py"

[Shiywa]

Hi, recently I met an error in saving stream figures. When I want to used CellRank, I installed three packages including mpi4py petsc petsc4py. then When I want to use

scv.pl.velocity_embedding_stream(adata, basis="harmony_umap", color="develop_anno",palette=color_dict,
                                save= "scvelo_Mock and Ctrl Macro scVelo lineage.png",figsize=(8,8),
                                 legend_loc= "right margin")

I got the error. Firstly, the cluster labels can't be displayed. Then the figure can't be saved by the function.

# paste your code here, if applicable
scv.pl.velocity_embedding_stream(adata, basis="harmony_umap", color="develop_anno",palette=color_dict,
                                save= "scvelo_Mock and Ctrl Macro scVelo lineage.png",figsize=(8,8),
                                 legend_loc= "right margin")
