Python中的Numpy、SciPy、MatPlotLib安装与配置

版本是2.7但是 安装NumPy是出现以下错误

python version 2.7 required,which was not found in the registry

原因  不能再注册表中识别出来python2.7

解决如下

        print "--- Python", version, "is now registered!"
        return
    if (QueryValue(reg, installkey) == installpath and
        QueryValue(reg, pythonkey) == pythonpath):
        CloseKey(reg)
        print "=== Python", version, "is already registered!"
        return
    CloseKey(reg)
    print "*** Unable to register!"
    print "*** You probably have another Python installation!"
 
if __name__ == "__main__":
    RegisterPy()

运行后再次

安装解决。

#安装完成后  64位的Python与 NumPy不兼容问题（当导包时出现错误）

两种方法

①是下载64位的

Python包numpy、Matplotlib、SciPy在64位Windows上的安装

②是下载32位的Python

# 实现32位和64位python共存，直接将winpython32位和64位分别解压到不同的目录就行了，然后重新配置环境
