Hi!
Sorry for late reply. Yes, the predictions of intermediate and the final layer are cast into numpy arrays. The simplest way to turn them into dataframes is to create a preprocessing step that takes the numpy . array and outputs a dataframe, that would like something like
class ToDF:
def __init__(self):
pass
def fit(self, *args, **kwargs):
return self
def transform(self, x):
if not isinstance(x, pd.DataFrame):
x = pd.DataFrame(x)
return x
I am using estimators that require dataframes as input, using the index values, it seems first layer accepts it, but when using the estimator in higher layers, the data will be sliced into ndarrays before passing into the 'fit' and 'predict_proba' functions of the estimator, is there a way to preserve them as dataframes when passing through? thanks
