tensorflow::ops::StringLength

#include <string_ops.h>

String lengths of input.

Summary

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

strings = tf.constant(['Hello','TensorFlow', '']) tf.strings.length(strings).numpy() # default counts bytes array([ 5, 10, 4], dtype=int32) tf.strings.length(strings, unit="UTF8_CHAR").numpy() array([ 5, 10, 1], dtype=int32)

Arguments:

  • scope: A Scope object
  • input: The strings for which to compute the length for each element.

Optional attributes (see Attrs):

  • unit: 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.

Returns:

  • Output: Integer tensor that has the same shape as input. The output contains the element-wise string lengths of input.
