本文介绍了额外字符:TensorFlow HelloWorld 验证正确安装的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是为了确保这里从 tensorFlow hello-world 收到的结果是好的hello-world 页面
This is to make sure the result received from tensorFlow hello-world here is fineThe hello-world page
如果Python程序输出如下，则说明安装成功，可以开始编写TensorFlow程序了.(如果您不熟悉 TensorFlow，请参阅 TensorFlow 入门.)
>你好，TensorFlow！
实际发生的是接收输出:
What happens actually is to receive the output:
b'Hello, TensorFlow!'
特别是它里面有一个额外的b"，这是不期望的.
In particular it has an extra ''b'' inside which is not expected.
推荐答案
b 不是字符串字符(不在引号内)而是前缀，表示字符串是一个字节包含 ASCII 字符的文字(与标准 python3 utf-8 编码相对).
The b is not a string character (it is not within the quotes) but a prefix, indicating that the string is a byte literal containing ASCII character (as opposed to the standard python3 utf-8 encoding).
另见这个问题.
