重装cvxpy库

先卸载cvxpy库 结果出现错误提示

一定要在开始里面启动cmd窗口进行卸载呀

pip uninstall cvxpy

ERROR: Exception:

解决办法：

通过网上搜索可能是因为电脑上运行这python程序（比如spyder 、jupyter notebook等），我们把python程序关闭再卸载

然后真的就卸载成功了 pip uninstall cvxpy

然后看D:\ProgramData\Anaconda3\Lib\site-packages也看不到cvxpy文件夹了

然后打开jupyter notebook（也可以在cmd窗口输入python来进入python环境）

输入import cvxpy 提示 ModuleNotFoundError: No module named 'cvxpy'

这样就卸载干净了
