I want to visualize cellphonedb results but I get several error. I do visualization by ktplotspy package. First, I read the required files based on its tutorials and when I try to create the heatmap, it gives an error:

code:

kpy.plot_cpdb_heatmap(
        adata=adata,
        pvals=pvals,
        celltype_key="celltype",
        figsize = (5,5),
        title = "Sum of significant interactions"
    )

Error:

>Traceback (most recent call last):
  File "/Users/pedram/opt/anaconda3/envs/CPDB-New/lib/python3.8/site-packages/pandas/core/indexes/base.py", line 3803, in get_loc
    return self._engine.get_loc(casted_key)

    indexer = self.columns.get_loc(key)

    raise KeyError(key) from err
KeyError: 'celltype'

I guess it might be related to the h5ad file but not sure. Also, if there is any suggestion regarding visualization of cpdb results, I welcome.
