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: �Ҳ���ָ����ģ�顣

原因是cmake检测到python环境，自动加入到编译项目，但本来并不打算引入python
解决办法：删除source目录下的CMakeLists.txt里的这一句
