禁用 TensorFlow/Numpy 弃用警告消息

Question

运行使用 tensorflow v1.14.0 的 Python 3.7.4 应用会导致出现大量弃用警告。以下代码清除了大部分内容。

try:
    from tensorflow.python.util import module_wrapper as deprecation
except ImportError:
    from tensorflow.python.util import deprecation_wrapper as deprecation
deprecation._PER_MODULE_WARNING_LIMIT = 0

但是，没有删除任何警告。将tensorflow 更新到 v2.x 目前不是一个选项。

如何删除这些消息？

Answer 1

您可以通过将以下代码放在脚本开头 (source) 来忽略所有“FutureWarning”警告：

from warnings import simplefilter 
simplefilter(action='ignore', category=FutureWarning)

请注意，您必须将这些行放在任何其他导入之前，因为其中一些可能已经自行导入依赖项。

Answer 2

概览

将我带到这里的问题实际上是来自tensorboard 中的代码的最近一个 numpy 弃用警告，但我希望这些原则也适用于 OP 中的问题。

方法

在任何tensorflow 导入之前添加以下内容将抑制由that specific module 引起的开发人员指导的DeprecationWarnings（默认情况下会忽略弃用警告，但它们可能会被打开，例如，QA 工具；请改用FutureWarnings如果弃用警告是针对最终用户的）：

from warnings import filterwarnings  # noqa
warnings.filterwarnings(action='ignore',
                        category=DeprecationWarning,
                        module='tensorflow')  # noqa                      

笔记

• 如果您正在开发多文件包，您可能会考虑将过滤器代码放在您的 __init__.py 文件的顶部（在任何 __future__ 导入之后）。
• 自动格式化程序（如black 或autopep8）可能会在有问题的导入之后 推送这些行。由于我在 VSCode 中使用了 autopep8-on-save 触发器，因此我还需要将 # noqa 添加到导入和过滤行中，以便它们不会被移动（参见 this post）。为避免需要为以下导入消除 linting 错误，另一种选择是将警告过滤行移至单独的 python 文件，然后从__init__.py 导入（请参阅this post）。
• （当然，对于我的tensorboard 问题，我使用了module='tensorboard'。）
