本文介绍了解决因Numpy版本过高而导致的一系列警告的方法。通过降级Numpy到1.14.5版本可以有效避免这些警告，确保Scipy等依赖库正常工作。

在新安装numpy之后运行python程序时可能会遇到以下警告：

/usr/local/lib/python2.7/dist-packages/scipy/linalg/basic.py:17: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88

此时可以检查以下numpy的版本

python
>>> import numpy
>>> numpy.__version__

若显示1.15.0及以上版本，则该警告是numpy版本过高所带来的。降级numpy版本即可，如1.14.5等：

sudo pip uninstall numpy
sudo pip install numpy==1.14.5
