See the guide: Control Flow > Control Flow Operations

Increments 'ref' until it reaches 'limit'.


  • ref: A mutable Tensor. Must be one of the following types: int32, int64. Should be from a scalar Variable node.
  • limit: An int. If incrementing ref would bring it above limit, instead generates an 'OutOfRange' error.
  • name: A name for the operation (optional).


A Tensor. Has the same type as ref. A copy of the input before increment. If nothing else modifies the input, the values produced will all be distinct.
