win10 64bit下python NLTK安装教程

由于最近需要做项目，需要进行分词等，查了资料之后，发现python NLTK很强大，于是就想试试看。在网上找了很多安装资料，都不太完整，下载的时候也总是会出现一点小意外，最后终于也安装成功了，所以分享下经验。

初学者，请高手指出不合理的地方。

我的工作站环境是Win10 64 + Python 2.7.12 64 bit。

按照NLTK上安装主页上的指引如下：

Source installation (for 32-bit or 64-bit Windows) 1.Install Python: http://www.python.org/download/releases/2.7.3/2.Install Numpy (optional): http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy3.Install Setuptools: http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11.win32-py2.7.exe4.Install Pip: Start>Run... c:/Python27/Scripts/easy_install pip5.Install PyYAML and NLTK: Start>Run... c:/Python27/Scripts/pip install pyyaml nltk6.Test installation: Start>All Programs>Python27>IDLE, then type import nltk

前3步的安装都比较简单，如果为了更好的编辑，也可以安装一下编辑软件，如PyCharm，Sublime text2/3等等。在安装的时候要注意安装路径，最好不要出现中文。

我在安装第4步的时候出现了一点小问题，执行命令后报错：Python version 2.7 required, which was not found in the registry，于是我又到网上查了资料，解决方法是：

1）自己新建一个register.py文件，在文件中复制黏贴以下内容，然后保存到自己的路径，我是直接放到pyhon的安装文件夹中；
