Hi Petar,

I would like to extremely thank you! I think that the TypeError was related 
to the Python 3.x version I'm using, so in layers.py I have modified line 
56 with center_margin = int((image_shape[2] - cropsize) / 2). Then lines 
104 to 107 with

self.filter_shape[0] = self.filter_shape[0] // 2
self.filter_shape[3] = self.filter_shape[3] // 2
self.image_shape[0] = self.image_shape[0] // 2
self.image_shape[3] = self.image_shape[3] // 2

line 125 with input[:self.channel // 2, :, :, :])
line 133 input[self.channel // 2:, :, :, :])
also line 168 dnn.dnn_conv(img=input_shuffled[:, :int(self.channel / 2),
and line 179 dnn.dnn_conv(img=input_shuffled[:, self.channel // 2:,

Once I resolved this issue the traceback reminds me other errors, regarding 
to TypeError float64 vector. This TypeError for me was related to "dtype 
constructor" (I referred to the 
http://deeplearning.net/software/theano/library/tensor/basic.html) I 
resolved the other errors in alex_net.py modifying line 26 with  y = 
T.ivector('y')

Actually training is still working, I don't know what kind of results it 
will give me, but for me now it is just a great result!
Thank you to everyone for your advices.
Goffredo
