line 51 in ops.py: add bias

[jiankang1991]

Hi,
Why do not you add bias term for the conv_transpose which is in the line 51 in ops.py?

convt = tf.nn.conv2d_transpose(x, w, output_shape=outputShape, strides=[1,2,2,1])

I think it should be:
convt = tf.nn.conv2d_transpose(x, w, output_shape=outputShape, strides=[1,2,2,1]) + b
