字符串常量的打印总是在TensorFlow中附加'b' [英] The print of string constant is always attached with 'b' inTensorFlow

问题描述

在对安装在 Windows 10 上的 TensorFlow r0.12(CPU) 进行测试时，我发现打印的字符串内容总是以b"结尾.python的打印是正常的.我无法弄清楚原因所以来这里寻求帮助.代码如下:

Durng the test of TensorFlow r0.12(CPU) installed on Windows 10, I found that the printed string contant is always with an 'b' in the end. The print of python is normal. I cannot figure out the reason so came here for help. The code is as follows:

>>>import tensorflow as tf
>>>hello = tf.constant('Hello, TensorFlow!')
>>>sess = tf.Session()
>>>print(sess.run(hello))
b'Hello, TensorFlow!'

推荐答案

使用 sess.run(hello).decode() 因为它是一个字节串.decode 方法将返回字符串.

Use sess.run(hello).decode() because it is a bytestring. decode method will return the string.

您的打印语句必须看起来像

Your print statement must look like

print(sess.run(hello).decode())
