tf.contrib.data.assert_element_shape

Assert the shape of this Dataset.

tf.contrib.data.assert_element_shape(expected_shapes)

Defined in contrib/data/python/ops/batching.py.

shapes = [tf.TensorShape([16, 256]), tf.TensorShape([None, 2])]
result = dataset.apply(tf.data.experimental.assert_element_shape(shapes))
print(result.output_shapes)  # ==> "((16, 256), (<unknown>, 2))"

If dataset shapes and expected_shape, are fully defined, assert they match. Otherwise, add assert op that will validate the shapes when tensors are evaluated, and set shapes on tensors, respectively.

Note that unknown dimension in expected_shapes will be ignored.

Args:

Returns:

A Dataset transformation function, which can be passed to tf.data.Dataset.apply
