【问题描述】:
我曾尝试将sys.path.append() 与os.getcwd() 一起使用,但没有成功。
来源来自here,我已经下载并提取它们:
alvas@ubi:~/test$ wget https://github.com/alvations/DLTK/archive/master.zip
alvas@ubi:~/test$ tar xvzf master.zip
alvas@ubi:~/test$ cd DLTK-master/; ls
dltk
alvas@ubi:~/test/DLTK-master$ cd dltk/; ls
tokenize
alvas@ubi:~/test/DLTK-master/dltk$ cd tokenize/; ls
abbrev.lex jwordsplitter-3.4.jar rbtokenize.pl
banana-split-standalone-0.4.0.jar koehn_senttokenize.pl splicer.py
igerman98_all.xml koehn_wordtokenize.pl tokenizer.py
__init__.py nonbreaking_prefix.de
alvas@ubi:~/test/DLTK-master/dltk/tokenize$ cat __init__.py
from tokenizer import punct_tokenize, rb_tokenize
from tokenizer import koehn_tokenize, deupunkt_tokenize
from splicer import jwordsplitter, jwordsplitteralvas
这些是我想从~/text/ 目录访问的功能,例如koehn_tokenize 函数。但我似乎无法将模块/函数添加到我的 python 解释器中。
alvas@ubi:~/test$ wget https://github.com/alvations/DLTK/archive/master.zip
alvas@ubi:~/test$ tar xvzf master.zip
alvas@ubi:~/test$ python
Python 2.7.5+ (default, Sep 19 2013, 13:48:49)

>>> import sys, os
>>> os.getcwd()
'/home/alvas/test'
>>> sys.path.append(os.path.join(os.getcwd(),'DLKT-master/dltk'))
['','/usr/local/lib/python2.7/dist-packages/...', ...,'/home/alvas/test/DLKT-master/dltk']
>>>
>>> import dltk
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named dltk
>>>
>>> from dltk.tokenize import koehn_tokenize
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named dltk.tokenize
从~/test/目录的python解释器,我如何访问dltk.tokenize模块?
如果将cd 转换为~/test/DLTK-master/dltk/tokenize,则该功能有效:
alvas@ubi:~/test$ cd DLTK-master/dltk/tokenize/
alvas@ubi:~/test/DLTK-master/dltk/tokenize$ python
Python 2.7.5+ (default, Sep 19 2013, 13:48:49)
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from __init__ import koehn_tokenize
>>>
但我不想在使用 python 解释器之前将cd 转换为~/test/DLTK-master/dltk/tokenize。我需要以某种方式在 python 中附加模块/函数。

尝试查看
__import__()并使用level参数
