bob.learn.mlp.Machine.__repr__ crashes

Created by: siebenkopf

The __repr__ method of bob.learn.mlp.Machine crashes, throughout. Try:

>>> import bob.learn.mlp
>>> m = bob.learn.mlp.Machine((1,1,1))
>>> print (m)

The reason is that the PyBobLearnMLPMachine_Repr method: https://github.com/bioidiap/bob.learn.mlp/blob/master/bob/learn/mlp/machine.cpp#L702 expects the PyBobLearnMLPMachine_getWeights to return a PyBlitzArray_Object*, while it actually returns a tuple: https://github.com/bioidiap/bob.learn.mlp/blob/master/bob/learn/mlp/machine.cpp#L261 Hence, NULL is passed to make_safe, which crashes with a SEGFAULT.
