我想得到反馈，了解我需要完成哪些选项或最佳选项。 我有一台较旧的Macbook Pro 2008,8GB RAM，10.8 Mountain Lion。 我安装了Virtualbox并设置了Ubuntu 12.04 VM。 安装Ubuntu的原因是为了能够运行一些我需要的perl脚本来收集数据并将它们放入MongoDB(我无法在OSX中执行此操作(
从MongoDB，我将把数据提取成可以输入到开源机器学习库中的格式......我想从scikit-learn开始。其他可能是WEKA和小规模的Hadoop(因为Hadoop也是我想开始学习使用的东西，所以我会用一块石头杀死两只鸟(。 甚至可能是图形实验室...
数据量不是很大，在Mongo之前是原始形式，现在总共约为3-4GB。
由于我有Ubuntu VM，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。 当我运行鼻子测试时，我收到错误并失败。
我已经阅读了各种选项，但不确定最好的方法是什么。 我是否使用适用于 Ubuntu 或 OSX 的预打包工具之一来运行 scikit learn 和 python3？ 如：EPD 顶篷或 http://docs.continuum.io/anaconda/pkgs.html 或 OSX https://github.com/fonnesbeck/ScipySuperpack
我是否忘记了 python3 并使用 python 2.7 并从源代码安装所有内容..？ Ubuntu 或 OSX 哪个是使用 scikit learn 和其他流行的免费机器学习库/工具的最佳选择？
提前感谢您的帮助和时间。
下面是运行鼻测试sklearn的输出 --exe 它是输出的尾迹结束。 由于字符限制并且由于存在错误，第一部分主要有警告。
