block function in resnet.py

[ljbthu]

I think that there is a small mistake when defining the 'bottleneck' structure in the block function .
In your code, three 1x1 conv layers ('a', 'b', 'c') are used to constitute the 'bottleneck' block.
I believe you forgot c['ksize'] = 3 when defining layer 'b'.

I think so. c['ksize'] should be definited 3 here.
