ValueError: Could not find stanford-postagger.jar file for hazm library- python NLP

I want to run a code that need to stanford postagger.jar. but i have this error:

  File "/usr/lib/python2.7/site-packages/nltk/internals.py", line 562, in find_jar
    (name, path_to_jar))
ValueError: Could not find stanford-postagger.jar jar file at resources/stanford-postagger.jar

How i can fix this error?

EDIT: i use from hazm module:

from hazm import POSTagger
tagger = POSTagger()
tagger.tag(word_tokenize('ما بسیار کتاب می‌خوانیم'))

and full result:

Traceback (most recent call last):
  File "pyt.py", line 8, in <module>
    tagger = POSTagger()
  File "/home/vahid/dev/hazm/hazm/POSTagger.py", line 14, in __init__
    super(stanford.POSTagger, self).__init__(*args, **kwargs)

Solution

You will first need the postagger.jar file from stanford and also train your own tagger. BUT the hazm dev has kindly uploaded the resource directory that you will need here: http://dl.dropboxusercontent.com/u/90405495/resources.zip

You will need to unzip and save the folder to the directory where you're running your script.

For example:

$ mkdir testdir
$ wget https://github.com/sobhe/hazm/archive/master.zip
$ unzip master.zip -d testdir
$ cd testdir
$ mv hazm-master/hazm/ .
$ wget http://dl.dropboxusercontent.com/u/90405495/resources.zip
$ unzip resources.zip -d .
