A bug in tutorial

[HelloWorldLTY]

Hi, I found that there is a bug existing in the velovi tutorial:

I think the input should not be a tutorial, so I check "ext_uncertainty_df",

and it is a tuple, but its 1st term is a dataframe.

So I think the code to generate uncertainty should be:

for c in ext_uncertainty_df[0].columns:
    adata.obs[c + "_extrinisic"] = np.log10(ext_uncertainty_df[0][c].values)

Based on this approach, I can generate the uncertainty plot.

Thanks a lot.
