+#  output = tf.nn.max_pool(value, [1, 3, 3, 1], [1, 2, 2, 1], 'VALID', name='maxpool2d')
+#  tf.get_default_graph().as_graph_def()
+#
+# NOTE 1. The output shape is 1x3x3x1
+#
+# >>> tf.graph_util.tensor_shape_from_node_def_name(tf.get_default_graph(), 'maxpool2d')

+#
+# NOTE 2. All the MaxPool nodes in inception v3 2018.04.27 use this configuration.
