So I followed the advice from Andreas but now I get this error when
calling clone:
PATH/scikit-learn/sklearn/base.pyc in clone(estimator, safe)
66 and param1.dtype == param2.dtype
67 # We have to use '.flat' for 2D arrays
---> 68 and param1.flat[0] == param2.flat[0]
69 and param1.flat[-1] == param2.flat[-1]
70 )
ValueError: The truth value of an array with more than one element is
ambiguous. Use a.any() or a.all()
I think that this could be because one of the parameters of __init__ is
a numpy array of objects, containing numeric numpy arrays.
Do you think I could just use Python's copy library in place of clone?

Thanks,
Michal
