import cvxopt ：ImportError: DLL load failed: 找不到指定的模块。

python3.7+win10导入cvxopt时提示，找不到指定的模块：

import cvxopt
Traceback (most recent call last):
  File "", line 1, in 
  File "D:\program\JetBrains\PyCharm 2019.2\helpers\pydev\_pydev_bundle\pydev_import_hook.py", line 21, in do_import
    module = self._system_import(name, *args, **kwargs)

numpy-kml: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
cvxopt: https://www.lfd.uci.edu/~gohlke/pythonlibs/#cvxopt
也可以用我放csdn上的：
numpy-kml： https://download.csdn.net/download/lxfhahaha/11449644
cvxopt：https://download.csdn.net/download/lxfhahaha/11451635

pip uninstall numpy cvxopt
pip install numpy-1.17.0+mkl-cp37-cp37m-win_amd64.whl
pip install cvxopt-1.2.3-cp37-cp37m-win_amd64.whl
然后再 import cvxopt 测试一下
