String lengths of input.

    input, name=None, unit='BYTE'

Computes the length of each string given in the input tensor.


  • input: A Tensor of type string. The string for which to compute the length.
  • unit: An optional string from: "BYTE", "UTF8_CHAR". Defaults to "BYTE". The unit that is counted to compute string length. One of: "BYTE" (for the number of bytes in each string) or "UTF8_CHAR" (for the number of UTF-8 encoded Unicode code points in each string). Results are undefined if unit=UTF8_CHAR and the input strings do not contain structurally valid UTF-8.
  • name: A name for the operation (optional).


A Tensor of type int32.
