在Python中运行tensorflow程序时，我已经安装了所有正确的东西.......它首先向我显示这个然后是输出。它不是警告或错误
请有人帮我解决它......

Answer 1

在文件顶部写入以下两行。

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'
import tensorflow as tf

使用上面的代码禁用所有日志记录。 这是三个级别

0 = all messages are logged (default behavior)
1 = INFO messages are not logged
2 = INFO, WARNING messages are not logged
3 = INFO, WARNING, and ERROR messages are not logged

您可以选择所需的日志记录级别。
