建议：2008 Mac w/OSX 10.8主机w/Virtualbox guest Ubuntu12.04设置python、scikit学习和；其他ML工具

我想得到关于我需要完成的事情有哪些选择或最佳选择的反馈。我有一个旧的MacBookPro 2008，8GB内存，10.8山狮。我安装了Virtualbox并安装了Ubuntu12.04虚拟机。Ubuntu安装的原因是能够运行一些收集数据所需的perl脚本，并将它们放入MongoDB（我在OSX中无法做到这一点）

从MongoDB中，我将把数据提取成可以输入开源机器学习库的格式。。我想从scikit learn开始。其他可能是WEKA和小规模Hadoop（因为Hadoop也是我想开始学习使用的东西，所以我会一箭双雕）。甚至可能是笔录

数据量不是很大，在Mongo之前是原始形式，现在大约有3-4GB

因为我有Ubuntu虚拟机，所以我决定用它来运行scikit learn。我在Ubuntu上安装了python3，然后是numpy、scipy、matplotlib，然后是scikitlearn。当我运行鼻测试时，我会出错并失败

我已经阅读了各种选择，不知道什么是最好的方式进行。为了能够运行scikit learn和python3，我是否使用Ubuntu或OSX上的预打包工具之一？例如：环保署Entought天篷或OSX

我是否忘记了python3而使用Python2.7并从源代码处安装了所有的东西。。？使用scikit learn和其他流行的免费机器学习库/工具的最佳选择是Ubuntu还是OSX

提前感谢您的帮助和时间
