Asserts tensor has expected shape.
tf.contrib.framework.with_shape( expected_shape, tensor )
If tensor shape and expected_shape, are fully defined, assert they match. Otherwise, add assert op that will validate the shape when tensor is evaluated, and set shape on tensor.
expected_shape: Expected shape to assert, as a 1D array of ints, or tensor of same.
tensor: Tensor whose shape we're validating.
tensor, perhaps with a dependent assert operation.
ValueError: if tensor has an invalid shape.
