tf.compat.v1.strings.length
Computes the length of each string given in the input tensor.
tf.compat.v1.strings.length(
input, name=None, unit='BYTE'
)
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)
Args |
|---|
input
|
A Tensor of type string. The strings for which to compute the
length for each element.
|
name
|
A name for the operation (optional).
|
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.
|
Returns |
|---|
A Tensor of type int32, containing the length of the input string in
the same element of the input tensor.
