Some problems about pool5/关于block5中pool的问题

[MioChiu]

net = slim.max_pool2d(net, [3, 3], stride=1, scope='pool5') The stride of pool5 is 1 and the size of it is [3,3],the default padding of slim.max_pool2d is 'VALID',why dont author set up padding？Without padding the size of output is [17,17] ，not [19,19]. 第五层pool层中步长为1，size为33 ，slim.max_pool2d默认的是padding='VALID'，这样算出来是1717, 但是我们在第七层的feature map要求是19*19啊，这里是否应该设置padding= 'SAME'

In ssd_vgg_300.py, the function ''ssd_arg_scope(...)'' has been set padding = ‘SAME’.
