为什么在Canopy上安装opencv时会降级numpy，scipy和其他程序包？

[英]Why does opencv on Canopy downgrade numpy, scipy, and other packages when I try to install it?

原文 2018-10-31 16:44:30 2 1 python-2.7/ opencv/ package/ enthought/ canopy

On my package manager for canopy, every time I try to download opencv it downgrades several other important packages. 在我的机盖软件包管理器上，每次我尝试下载opencv时，它都会降级其他几个重要的软件包。 I am then not able to upgrade those same packages or run my code. 然后，我将无法升级那些相同的程序包或运行我的代码。 How can I download opencv without downgrading my other packages? 如何在不降级其他软件包的情况下下载opencv？

You haven't provided any version or platform information. 您尚未提供任何版本或平台信息。 But perhaps you are using an old Canopy version (current is 2.1.9), or perhaps you are using the subscriber-only "full" installer, which is only intended for airgapped or other non-updateable systems. 但是，也许您使用的是Canopy的旧版本（当前版本是2.1.9），或者您使用的是仅订阅者的“完整”安装程序，该安装程序仅用于气隙式或其他不可更新的系统。 Otherwise, the currently supported version of opencv is 3.2.0 (build 3.2.0-4) which depends on numpy 1.13.3, which is the currently supported version of numpy. 否则，当前受支持的opencv版本是3.2.0（内部版本3.2.0-4），它取决于numpy 1.13.3（当前受支持的numpy版本）。
