在不能上網的服務器上把nltk_data關聯到python3，已經安裝anaconda3所以不需要安裝nltk，環境是linux

首先沒有nltk_data在使用nltk會報錯

LookupError: 
**********************************************************************
  Resource ‘tokenizers/punkt/PY3/english.pickle‘ not found.
  Please use the NLTK Downloader to obtain the resource:  >>>

    - ‘/usr/share/nltk_data‘
    - ‘/usr/local/share/nltk_data‘
    - ‘/usr/lib/nltk_data‘
    - ‘/usr/local/lib/nltk_data‘
    - ‘/home/hadoopcj/nltk_data‘
    - ‘‘

1.下載nltk_data

https://github.com/nltk/nltk_data

裏面的Packages就是我們要的資源。
2.裏面有部分是壓縮包，需要解壓。punkt就是，不解壓即使路徑對了還是會報上面的錯誤

3.將Packages文件夾改名為nltk_data，拷貝到服務器

4.進入python console（如輸入/home/hadoopcj/anaconda3/bin/python3.6）在nltk添加你data的路徑

>>>from nltk import data
>>>data.path.append(r"/home/hadoopcj/nltk_data(你的路徑)")

5.查看nltk_data的搜索路徑，如果有你添加的就成功了

>>> nltk.data.path

>>> nltk.data.path
[
 
‘/home/hadoopcj/nltk_data‘, ‘/usr/share/nltk_data‘, ‘/usr/local/share/nltk_data‘, ‘/usr/lib/nltk_data‘, ‘/usr/local/lib/nltk_data‘]

linux下python3離線加載nltk_data，不用nltk.download()
