tf.raw_ops.StringLength(
    input, unit='BYTE', name=None
)
 Computes the length of each string given in the input tensor. 
strings = tf.constant(['Hello','TensorFlow', '\U0001F642'])
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)

 


 Args
  input   A Tensor of type string. The strings for which to compute the length for each element.  
  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).   
 


 Returns   A Tensor of type int32.
