停止 TensorFlow 打印警告消息

Question

我正在使用 Kaggle 笔记本，每当我运行一个完全引用 TensorFlow 模块的单元格时，它都会打印出关于某种设置的巨大警告，但仍然有效。我查找了如何抑制来自 TensorFlow 的警告，我发现的所有内容都说要执行以下操作：

import os
os.environ["TF_CPP_MIN_LOG_LEVEL"] = "2" # Or "3", either one should work and I've tried both

我曾尝试在导入 TensorFlow 之前和之后放置它，但无济于事。该消息仍然打印出来。这是我收到的消息：

有什么方法可以阻止它打印吗？

编辑：重现此消息的代码：

import tensorflow as tf
tf.constant(())

编辑：env 的输出：

Answer 1

所以我设法通过以下行解决了问题：

os.environ["KMP_SETTINGS"] = "false"
