SNN_RBM shape mismatch #15

Description

@CorpaciLC

Hi,

When running SNN_RBM.py on the datasets from the paper (tried on 1458 and 2261), we get the following error:

'''
../../make-ipinyou-data/2261/train.yzx.txt

ValueError: Shape mismatch: x has 37 cols (and 1 rows) but y has 70 rows (and 300 cols)

During handling of the above exception, another exception occurred:

Apply node that caused the error: Dot22(Elemwise{Mul}[(0, 0)].0, ww)
Toposort index: 12
Inputs types: [TensorType(float64, matrix), TensorType(float64, matrix)]
Inputs shapes: [(1, 37), (70, 300)]
Inputs strides: [(296, 8), (2400, 8)]
Inputs values: ['not shown', 'not shown']
Outputs clients: [[Elemwise{Composite{scalar_sigmoid((i0 + i1))}}[(0, 0)](Dot22.0, InplaceDimShuffle{x,0}.0)]]

Backtrace when the node is created(use Theano flag traceback.limit=N to make it longer):

HINT: Use the Theano flag 'exception_verbosity=high' for a debugprint and storage map footprint of this apply node.
