禁用 Tensorflow 调试信息

Question

我所说的调试信息是指 TensorFlow 在我的终端中显示的关于加载的库和找到的设备等信息，而不是 Python 错误。

Answer 1

您可以使用 os.environ 禁用所有调试日志：

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

在 tf 0.12 和 1.0 上测试

在细节上，

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