TypeError: void() takes exactly 1 positional argument (0 given)

[clg12]

When I load the f_final_loom into a scanpy.AnnData object, I get the following error.

adata.obs.drop(['Embedding','Embeddings_X','Embeddings_Y','RegulonsAUC'],axis=1,inplace=True)
TypeError: void() takes exactly 1 positional argument (0 given)

And the content of obs:
obs: 'ClusterID', 'Clusterings', 'Embedding', 'Embeddings_X', 'Embeddings_Y', 'Louvain_clusters_Scanpy', 'Percent_mito', 'RegulonsAUC', 'nGene', 'nUMI'

I encountered the same error, any update on this?

Interaction of pandas and numpy causes this. adata = sc.read( f_final_loom, validate=False) makes a column of adata.obs contains numpy structured array ('Clusterings')
adata.obs.pop('Clusterings') may help
Anyway this step is just deleting these columns. You can do this with any valid method. Alternately, we can just left them there.
