Question

我真的很擅长使用Python和可以安装的相关软件包。作为一名生物学家，我正在寻找许多可以帮助我模拟物种系统，生态变化等的新包装。经过大量的“Google-ing”之后，我遇到了scikit-learn。但是，我在安装它时遇到了问题。现在我将采取这一时刻为这篇文章的篇幅道歉。

我正在使用64位Python 3.3并且具有相关的NumPy（MKL 1.7.0）和SciPy。我安装了分发工作正常，并允许我使用easy_install。所以要安装scikit-learn，我尝试使用cmd提示符（Windows）以管理员模式运行，然后也通过Python命令行运行。我将下载并解压缩的tar.gz文件放在Lib \ site-packages文件夹中。当我运行命令 easy_install scikit-learn 在cmd提示符下。然后这是以下输出：

C:\Python33\Lib\site-packages>easy_install -U scikit-learn

所以小^似乎指向“在带有％r的RNGS之后。我可以告诉它来自.tar中找到的sklearn文件夹中的' init '文件。 gz文件。

在Python GUI和命令行中运行它时，我也得到相同的结果。

如何使用Python 3.3安装scikit-learn？有没有办法构建它或编辑文件以通过这个无效的语法错误？

非常感谢任何帮助。我很抱歉这么长的帖子。我只是想在那里得到所有细节。

由于西蒙

Answer 1

scikit-learn还不支持Python 3。现在你需要Python 2.7。

对于计划于2013年第二季度发布的0.14版本，预计将对Python 3提供适当的支持。

Answer 2

我不是专家，但据我所知，Python 3中的print语句现在是一个函数，名为：print（）。因此，在这种情况下，快速解决方案是改变

print "I: Seeding RNGs with %r" % _random_seed

到

print("I: Seeding RNGs with %r" % _random_seed)

在Windows 7上安装scikit-learn for python 3.3
