在64位Windows上安装NumPy和SciPy(使用Pip) [英] Installing NumPy and SciPy on 64-bit Windows (with Pip)

问题描述

我发现在64位Windows上无法通过安装程序安装NumPy/SciPy，而只能在32位上安装.因为我需要的内存比32位安装所能提供的更多，所以我需要所有内容的64位版本.

I found out that it's impossible to install NumPy/SciPy via installers on Windows 64-bit, that's only possible on 32-bit. Because I need more memory than a 32-bit installation gives me, I need the 64-bit version of everything.

我试图通过Pip安装所有内容，并且大多数工作正常.但是，当我来到SciPy时，它抱怨缺少一个Fortran编译器.因此，我通过MinGW/MSYS安装了Fortran.但是之后您不能立即安装SciPy，需要重新安装NumPy.所以我尝试了一下，但是现在通过Pip或easy_install都不再起作用了.两者都给出以下错误:

I tried to install everything via Pip and most things worked. But when I came to SciPy, it complained about missing a Fortran compiler. So I installed Fortran via MinGW/MSYS. But you can't install SciPy right away after that, you need to reinstall NumPy. So I tried that, but now it doesn't work anymore via Pip nor via easy_install. Both give these errors:

• 关于LNK2019和LNK1120的错误很多.
• 我在C范围内遇到很多错误:C2065, C2054 , C2085 , C2143`，等等.我认为它们属于同一类.
• 没有找到Fortran链接器，但是我不知道如何安装它，找不到任何内容.
• 我的cmd-windows的可见部分中已经出现了许多错误...

• 致命错误约为LNK1120:

• There are a lot of errors about LNK2019 and LNK1120,.
• I get a lot of errors in the range of C: C2065,C2054,C2085,C2143`, etc. They belong together I believe.
• There is no Fortran linker found, but I have no idea how to install that, can't find anything on it.
• And many more errors which are already out of the visible part of my cmd-windows...

• The fatal error is about LNK1120:

在64位Windows计算机上安装64位版本的NumPy和SciPy的正确方法是什么?我有什么想念的吗?我是否需要在某处指定内容?对于Windows，我没有找到关于这些问题的信息，仅针对Linux或Mac OS X，但是它们对我没有帮助，因为我无法使用其命令.

What is the correct way to install the 64-bit versions NumPy and SciPy on a 64-bit Windows machine? Did I miss anything? Do I need to specify something somewhere? There is no information for Windows on these problems that I can find, only for Linux or Mac OS X, but they don't help me as I can't use their commands.

推荐答案

Numpy项目现在提供了wheel格式的预编译软件包(软件包格式允许以二进制形式在软件包中进行编译)，因此现在的安装方式为和其他软件包一样简单.

The Numpy project now provides pre-compiled packages in the wheel format (package format enabling compiled code as binary in packages), so the installation is now as easy as with other packages.

Numpy(还有一些其他软件包，如Scipy，Pandas等)包括很多C-，Cython和Fortran代码，在使用它们之前需要进行正确编译.顺便说一句，这也是这些Python软件包提供如此快速的线性代数的原因.

Numpy (as also some other packages like Scipy, Pandas etc.) includes lot's of C-, Cython, and Fortran code that needs to be compiled properly, before you can use it. This is, btw, also the reason why these Python-packages provide such fast Linear Algebra.

要获取Windows的预编译包，请查看 Gohlke的非官方Windows二进制文件或使用类似 Winpython 的发行版(可以正常使用)或

To get precompiled packages for Windows, have a look at Gohlke's Unofficial Windows Binaries or use a distribution like Winpython (just works) or Anaconda (more complex) which provide an entire preconfigured environment with lots of packages from the scientific python stack.
