Assert that x has rank equal to rank.

tf.debugging.assert_rank(
    x, rank, message=None, name=None
)

This Op checks that the rank of x is equal to rank.

If x has a different rank, message, as well as the shape of x are printed, and InvalidArgumentError is raised.

Args:

• x: Tensor.
• rank: Scalar integer Tensor.
• message: A string to prefix to the default message.
• name: A name for this operation (optional). Defaults to "assert_rank".

Returns:

Op raising InvalidArgumentError unless x has specified rank. If static checks determine x has correct rank, a no_op is returned. This can be used with tf.control_dependencies inside of tf.functions to block followup computation until the check has executed.

Raises:

• InvalidArgumentError: if the check can be performed immediately and x does not have rank rank. The check can be performed immediately during eager execution or if the shape of x is statically known.
