Image data of dtype object cannot be converted to float

Hello dynamo. I met this issue when trying to run the scNT-seq human hematopoiesis. What should I do to change the dtype from object to float? Thank you very much.

`%matplotlib inline

dyn.vf.jacobian(adata_labeling, regulators=[“SPI1”, “GATA1”], effectors=[“SPI1”, “GATA1”]) dyn.pl.response( adata_labeling, np.array([[“SPI1”, “GATA1”], [“GATA1”, “SPI1”], [“SPI1”, “SPI1”], [“GATA1”, “GATA1”]]), ykey=“jacobian”, log=False, drop_zero_cells=True, grid_num=25, figsize=(5, 3), save_show_or_return=“show” )

Very great result.
