本文介绍了Windows + virtualenv + pip + NumPy(安装NumPy时出现的问题)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

在 Windows 上,我通常只使用二进制安装程序,但我想安装 NumPy这次只在虚拟环境中,所以我创建了一个虚拟环境:

On Windows, I normally just use the binary installer, but I would like to install NumPy only in a virtualenv this time, so I created a virtual env:

virtualenv --no-site-packages --distribute summary_python
cd summary_python/Scripts
activate.bat

然后我尝试安装 NumPy

Then I tried to install NumPy

pip install numpy

我得到一个错误.我的 pip.log 粘贴在下面:

And I get an error. My pip.log is pasted below:

推荐答案

我已经成功地将 NumPy 二进制文件安装到 virtualenv 中,并具有良好的ol easy_install"和一点解压魔法.

I've had success installing NumPy binaries into a virtualenv with good 'ol easy_install and a little bit of un-archiving magic.

您从 numpy-1.xx-win32-superpack-python2.x.exe 版本="nofollow noreferrer">SourceForge 实际上只是三个独立二进制发行版的薄包装(使用 SSE3SSE2 或不启用 SSE,具体取决于 CPU 的功能).如果您在 7-Zip(或其他存档实用程序)中打开 superpack EXE 文件,您可以将这些单独的设置文件提取到某个地方以单独使用.

The numpy-1.x.x-win32-superpack-python2.x.exe release you download from SourceForge is really just a thin wrapper around three separate binary distributions (with SSE3, SSE2, or no SSE enabled, depending on the capabilities of your CPU). If you open up the superpack EXE file in 7-Zip (or another archive utility), you can extract those individual setup files somewhere to use separately.

然后,激活您的虚拟环境,然后运行

Then, activate your virtual environment, and run

easy_install c:path	oextracted
umpy-1.x.x-sse3.exe

例如,安装 SSE3 优化的二进制文件.easy_install 足够聪明,可以在 wininst 包中找到它需要的一切,并将提取编译后的 egg 放入你的 virtualenv 的 site-packages 文件夹中.我还可以确认,当您执行此操作时,pip 仍然能够识别和/或卸载 NumPy,并且使用 pip 安装依赖于 NumPy 的其他软件包工作正常.

to install the SSE3-optimized binaries, for example. easy_install is smart enough to find everything it needs inside that wininst bundle and will extract the compiled egg into your virtualenv's site-packages folder. I can also confirm that pip is still able to recognize and/or uninstall NumPy when you do this, and that using pip to install other packages which depend on NumPy works just fine.

唯一的问题是知道要使用哪个优化级别(SSE3、SSE2 或 no-SSE).如果你有一个相当现代的处理器(比一个Pentium 4Athlon 64),使用完整的 SSE3 可能是安全的.您也可以运行测试套件以确认一切正常.

The only catch is knowing which optimization level to use (SSE3, SSE2, or no-SSE). If you have a reasonably modern processor (newer than, say, a Pentium 4 or Athlon 64), it's probably safe to go with the full SSE3. You can probably also run the test suite to confirm everything works as expected.

我发现 easy_install 技巧"对于将各种二进制包安装到 virtualenv 中非常有用.尽管我在我的机器上设置了所有必需的编译器,但在提供官方版本时坚持使用它通常更容易/更快/更安全.

I've found the easy_install "trick" to be really useful for installing all sorts of binary packages into a virtualenv. Even though I have all the requisite compilers set up on my machine, it's usually easier/faster/safer to stick with the official release when one is provided.
