Assert that x has rank equal to 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.


  • 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".


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.


  • 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.
