ValueError: could not broadcast input array from shape (54289,1) into shape (54289,)

When using the train algorithm with zoom level 7 on an image with 8 level of depth, a model is generated but when we use this model with this software, I got the following error :

ValueError: could not broadcast input array from shape (54289,1) into shape (54289,)
on the line
y = np.array(self._pyxit.base_estimator.predict_proba(subwindows))
