ImportError: Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. If you're working with a numpy git repo, try `git clean -xdf` (removes all files not under version control). Otherwise reinstall numpy. Original error was: DLL load failed:
anaconda创建的python=3.6环境下，使用conda list 发现2个numpy，一个是<pip>安装，另一个清华镜像安装，pip uninstall numpy conda remove numpy先删除再安装conda install numpy，然而并不好用
原因：版本问题
解决方案：
全部删除之后，
conda upgrade numpy
解决！
如果是pip安装的，直接pip install --upgrade numpy
