scikit-learn - Keras with ensembles

Question

I'm building ensemble such as Voting using SKlearn and Stacking using brew. However, I Keras wrapper doesn't work correctly.

Building the Voting classifier I receive when one of the elements if KerasClassifier gives me folowing error:

TypeError: cannot create 'sys.flags' instances

Building Stacking classifier I'm getting:

AttributeError: 'Sequential' object has no attribute 'classes_'

How could I use Keras with ensembles? Do I have to change framework?

Answer 1

尝试KerasClassifier用CalibratedClassifierCV这样的对象包装对象：

from sklearn.calibration import CalibratedClassifierCV
model = CalibratedClassifierCV(KerasClassifier(...))

从此答案中引用。
