TypeError: 'NoneType' object cannot be interpreted as an index

I have tried to run the mnist_ladder.py example without changing anything, it gives me following error. Would you please tell me what I'm doing wrong?

Lambdas: [1000.0, 10.0, 0.1, 0.1, 0.1, 0.1, 0.1] h6: (200, 10) y_weights_decoder: (0, 10) Traceback (most recent call last): File "mnist_ladder.py", line 268, in <module> h6_dec, name='dec_normalize6'), name='dec_scale6') File "/home/usr/parmesan/parmesan/layers/normalize.py", line 61, in __init__ super(NormalizeLayer, self).__init__(incoming, **kwargs) File "/home/usr/venv/local/lib/python2.7/site-packages/Lasagne-0.1-py2.7.egg/lasagne/layers/base.py", line 38, in __init__ self.input_shape = incoming.output_shape File "/home/usr/venv/local/lib/python2.7/site-packages/Lasagne-0.1-py2.7.egg/lasagne/layers/base.py", line 52, in output_shape return self.get_output_shape_for(self.input_shape) File "/home/usr/venv/local/lib/python2.7/site-packages/Lasagne-0.1-py2.7.egg/lasagne/layers/shape.py", line 380, in get_output_shape_for range(*self.slice.indices(input_shape[self.axis]))) TypeError: 'NoneType' object cannot be interpreted as an index

Sounds like the same error as here #37

you need to update Lasagne i think (see http://lasagne.readthedocs.io/en/latest/user/installation.html#bleeding-edge-version)
