如何修复安装Python软件包cvxpy的错误

如何解决如何修复安装Python软件包cvxpy的错误

我正在使用Windows 10和Anaconda，并尝试使用命令提示符安装Python软件包'cvxpy'。我不断收到相同的错误消息。我尝试使用conda安装软件包，重新安装Anaconda，并在Anaconda安装过程中尝试检查/取消选中两个复选框选项，将路径设置为默认路径。

我是新来的，并且拒绝使用虚拟环境和/或设置虚拟Linux机器，但是现在我将尝试下一个。

C:\Users\john>py -m pip install cvxpy

解决方法

这是由numpy 1.19.4引起的已知错误，请尝试取消安装1.19.4版本并安装numpy 1.19.3。

希望它对您有用。
