未来警告：不赞成将issubdtype的第二个参数从“float”转换为“np.floating”

Question

在更新了我的Numpy和Tensorflow之后，我收到了这些警告。我已经试过these，但没什么用，每一个建议都会受到赞赏。

FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
  from ._conv import register_converters as _register_converters

Answer 1

你可以升级h5py

pip install --upgrade h5py

Answer 2

这可能是您的情况，也可能不是您的情况，但同样的警告也会从h5py包中发出：

/home/user/bin/conda3/lib/python3.6/site-packages/h5py/__init__.py:34: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated. In future, it will be treated as np.float64 == np.dtype(float).type. from ._conv import register_converters as _register_converters

对于任何带着这个问题来这里的人来说，它是一个known h5py issue，由numpy 1.14引入的。如开发人员所述：

You can ignore the warning, it's not going to cause any issues at the moment, but you should upgrade to the next release of h5py when it becomes available.

。。。所以是无害的。修复程序刚刚merged到master。但在更新发布之前，解决方法是将numpy降级到以前的版本：

pip install numpy==1.13.0

使用修复更新RC构建。应使用以下命令：

pip install h5py==2.8.0rc1

更新（最终版）：现在有一个完整的版本。所以你可以简单地运行：

pip install --upgrade h5py

Answer 3

我试过这些，它也为我解决了同样的问题，只要把这些放在你的代码上面

import os
os.environ["TF_CPP_MIN_LOG_LEVEL"]="3"
