在Windows上,我通常只使用二进制安装程序,但是这次我只想在virtualenv中安装NumPy,因此我创建了一个虚拟env:
virtualenv --no-site-packages --distribute summary_python
cd summary_python/Scripts
activate.bat
然后我尝试安装NumPy
pip install numpy
我得到一个错误。我的pip.log粘贴在下面:

参考方案
我已经成功地将NumPy二进制文件安装到具有良好的'ol easy_install
和一点未归档魔术的虚拟环境中。
您从SourceForge下载的numpy-1.x.x-win32-superpack-python2.x.exe
版本实际上只是围绕着三个单独的二进制发行版的薄包装(根据您的CPU功能,启用SSE3,SSE2或不启用SSE)。如果在7-Zip(或另一个存档实用程序)中打开superpack EXE文件,则可以将这些单独的安装文件提取到某个地方以单独使用。
然后,激活您的虚拟环境,然后运行
easy_install c:\path\to\extracted\numpy-1.x.x-sse3.exe
例如,安装经过SSE3优化的二进制文件。 easy_install
足够聪明,可以在wininst
包中找到它所需的所有内容,并将已编译的egg提取到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安装其他依赖于NumPy的软件包也可以。
唯一的困难是知道要使用哪个优化级别(SSE3,SSE2或否-SSE)。如果您有reasonably modern processor(比Pentium 4或Athlon 64更新),则使用完整的SSE3可能是安全的。您可能还可以运行测试套件以确认一切正常。
我发现easy_install
“trick”对于将各种二进制程序包安装到virtualenv中非常有用。即使我的机器上已经安装了所有必需的编译器,但提供官方版本时,通常更容易/更快/更安全。
我有预先存在的python和C ++文件,其中python文件定义了许多点,而C ++代码利用其现有库进行了所需的计算。最终产品是C ++代码写入的文件。我正在寻找一种在python中获取2000点列表的方法,将其传递给函数,然后执行所有C ++代码并输出我需要的文件。其他注意事项。这必须是可以在Linux或Windows机器上工作的东西,并且最少安装新插件…
扩展Python时可以使用C++功能吗? - c++Python手册说您可以在C和C++中为Python创建模块。使用C++时可以利用类和模板之类的东西吗?它不会与其他库和解释器产生不兼容吗? 参考方案 挂钩函数的实现是用C还是用C++实现都没有关系。实际上,我已经看过一些Python扩展,这些扩展有效利用C++模板甚至Boost库。没问题。 :-)
将Python嵌入C++应用程序 - c++上下文:我们一直面临的一个持续问题是对我们的市场数据应用程序进行单元测试。这些应用程序坐下来观察从提要中检索到的数据并执行某些操作。一些很难触发的关键事件很少发生,并且测试人员很难在所有情况下验证我们的应用程序是否正常运行,因此我们必须依靠单元测试。这些系统通常通过在事件发生时发出回调(进入我们的应用程序)来工作,然后由我们负责处理此事件。 我设想的解决方案…
在Java中,执行“ ++++++++”表达式,编译器未报告任何错误并且可以正确执行? - java我用eclipse编写了这段代码,用war写过,结果为3d。public static void main(String[] args) { double a = 5d + + + + + +-+3d; System.out.println(a); } 参考方案 您的表情可以改写为(5d) + (+ + + + +-+3d) 其中第一个+是应用于两个操作数的…
从C++调用Python函数 - c++我正在尝试从C++实现调用Python函数。我以为可以通过函数指针来实现,但是似乎不可能。我一直在使用boost.python完成此操作。假设在Python中定义了一个函数:def callback(arg1, arg2): #do something return something 现在,我需要将此函数传递给C++,以便可以从那里调用它。如何使用boos…
