ERROR 'The truth value of a DataFrame is ambiguous'

[wook2014]

I used SpliZ for running my SICILIAN data and meet a problem about The truth value of a DataFrame is ambiguous. It seemed that the problem caused by loss of to_dict() in file rijk_score.py line 358 and line 390.
the code used to be:

df["cov"] = df["geneR1A_uniq"].map(grouped.apply(lambda x: x['z_A'].cov(x['z_B'])))
df["cov_{}".format(y)] = df["geneR1A_uniq"].map(grouped.apply(lambda x: x['z_A_{}'.format(y)].cov(x['z_B_{}'.format(y)])))

and it shoule be fixed to:

df["cov"] = df["geneR1A_uniq"].map(grouped.apply(lambda x: x['z_A'].cov(x['z_B'])).to_dict())
df["cov_{}".format(y)] = df["geneR1A_uniq"].map(grouped.apply(lambda x: x['z_A_{}'.format(y)].cov(x['z_B_{}'.format(y)])).to_dict())

You can refer to https://figshare.com/articles/dataset/Tables_and_Data_for_SpliZ_Manuscript/14378819/1
This is the data provided by author. the 4 .pq file can absolutely correctly run with SpliZ.
I just tried to run SpliZ to make sure it worked on our HPC so I did not do more about it. But as far as I know it should be provided by some more information about cell type which might from Seurat or other single cell data analyse tools.
