MCA : 'SparseDataFrame' object has no attribute 'to_numpy'
See original GitHub issueI’m trying to execute the following code -
import prince
mca = prince.MCA(n_components=10,n_iter=5,copy=True,check_input=True,engine='auto',random_state=10)
mca_model=mca.fit(df_sample)
The problem is that OneHotEncoder has sparse set to True, so it returns a sparse dataframe. But the fit function has the following piece of code -
if isinstance(X, pd.DataFrame):
X = X.to_numpy()
But to_numpy cannot be applied to sparse dataframes. As a result I’m getting the following error-
AttributeError: ‘SparseDataFrame’ object has no attribute ‘to_numpy’
Not sure if this is a bug or if i’m doing something wrong.

Yep, got it.
I’m on holiday at the moment, but I’ll work on it when I get back in ~10 days.
No, sorry. You are right - I got it working now with an older version of pandas. Thank you!
