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 ifunit=UTF8_CHARand theinputstrings do not contain structurally valid UTF-8.
Returns:
-
Output: Integer tensor that has the same shape asinput. The output contains the element-wise string lengths ofinput.
