如何获得TensorFlow字符串的长度？

Question

有没有办法在TensorFlow中获取TensorFlow字符串的长度？例如,是否有任何函数返回a = tf.constant("Hello everyone", tf.string)as 的长度14而不将字符串传递回Python.

Answer 1

这对我有用:

x = tf.constant("Hello everyone")

# Launch the default graph.
with tf.Session() as sess:
    print(tf.size(tf.string_split([x],"")).eval())
