tf.assert_proper_iterable(values)
Static assert that values is a "proper" iterable.
Ops that expect iterables of Tensor can call this to validate input. Useful since Tensor, ndarray, byte/text type are all iterables themselves.
Args:
values: Object to be checked.
Raises:
TypeError: If values is not iterable or is one of Tensor, SparseTensor, np.array, tf.compat.bytes_or_text_types.
