RuntimeWarning: numpy.dtype大小更改，可能表示二进制不兼容
提问于 2016-11-28 13:17:48
我有一个错误，试图加载一个保存的支持向量机模型。我试着卸载sklearn，NumPy和SciPy，重新安装最新版本(使用pip)。我还在犯这个错误。为什么？

pip uninstall -y scipy scikit-learn
pip install --no-binary scipy scikit-learn这个错误现在已经消失了，虽然我仍然不知道为什么会发生这样的事情.

这是新的numpy版本的问题(1.15.0)
您可以降级numpy，这个问题将得到解决：
sudo pip uninstall numpy
sudo pip install numpy==1.14.5
最后，numpy 1.15.1版本发布，所以警告问题是固定的。 sudo安装numpy==1.15.1
这很管用..。

我试过上面提到的方法，但都没有用。但是当我通过apt安装了库之后，这个问题就消失了，
对于Python3，
pip3 uninstall -y numpy scipy pandas scikit-learn
sudo apt update
sudo apt install python3-numpy python3-scipy python3-pandas python3-sklearn 对于Python2，
pip uninstall -y numpy scipy pandas scikit-learn
sudo apt update
sudo apt install python-numpy python-scipy python-pandas python-sklearn 希望这能有所帮助。

只需升级你的numpy模块，现在是1.15.4。适用于窗户
