Assert that x has rank of at least rank.

    x, rank, message=None, name=None

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

If x has a rank lower than 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_at_least".


Op raising InvalidArgumentError unless x has specified rank or higher. 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: x does not have rank at least rank, but the rank cannot be statically determined.
  • ValueError: If static checks determine x has mismatched rank.
