Hello, 

I'm not sure if my implementation is correct so I'm here to ask for 
recommendation. 


my input is of the size (66,100,100,3)  
66 = batch size 
100,100 width and height 
3 is the image depth since it is colored. 
 
so the first I do is to shuffle the input into 

self.layer0_input = input.reshape((66, 3, 100, 100))


I'll just talk about the first convolution. I'm using as a first layer 
convolution of 3 by 3 dimension with depth 32 so my result is of size 
(66,32,98,98) without pooling 


later to add the bias I have to shuffle the vector b from 1D 32 into 

self.b.dimshuffle('x', 0, 'x', 'x')


I don't know if the implementation is correct so each b is added and 
broadcasted into each kernel. In order to check the result 


I printed the result of the convolution and the result after adding the bias or 
in a different way I implemented this 


print conv[0][0] - conv_b[0][0]


so here I check if the same bias is added to the full batch or single depth in 
the first layer. the result is good so the b is added correctly to kernel.

I wanted to check to which bias this result belong by printing the the value of 
the bias and it turned out to be different non of the values belong to the list 
of the biases 


here is the values of the biases

and here is the result of 

or idx in xrange(32):

    print conv[0][idx][0][0] - conv_b[0][idx][0][0]

0.0  



I think there might be a mistake in the implementation.
