tf.strings.length
String lengths of input.
tf.strings.length(
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.
