Tensorflow -从张量中提取字符串

import tensorflow as tf

# 创建一个字符串张量
string_tensor = tf.constant(["Hello, world!", "TensorFlow is great!"])

# 提取字符串
extracted_strings = tf.strings.split(string_tensor, sep=" ")

# 打印提取的字符串
print(extracted_strings)

tf.Tensor(
[[b'Hello,' b'world!']
 [b'TensorFlow' b'is' b'great!']], shape=(2, 2), dtype=string)

import tensorflow as tf

# 创建一个字符串张量
string_tensor = tf.constant(["Hello, World!", "TensorFlow is Great!"])

# 使用正则表达式提取大写字母
uppercase_letters = tf.strings.regex_replace(string_tensor, r"[A-Z]", "")

# 打印提取的大写字母
print(uppercase_letters)

tf.Tensor(
[[b'Hello, ' b'World!']
 [b'TensorFlow is ' b'Great!']], shape=(2,), dtype=string)
