title: how to set stride to zero when using tf.layers.conv2d
body: <p>is there a way that I can turn off stride in tensor flow when using: tf.layers.conv2d()? According to the docs, the default is (1,1) but when I try to change this to (0,0) I get an error telling me that it has to be a positive number.</p>
  
  <p>Thanks.</p>
