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

I want to run the code that stanford postagger.jar needs. 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 can I fix this error?

EDIT: I am using the hazm module:

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

and the 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)
  File "/usr/lib/python2.7/site-packages/nltk/tag/stanford.py", line 42, in __init__
    verbose=verbose)
  File "/usr/lib/python2.7/site-packages/nltk/internals.py", line 562, in find_jar

First you need the postagger.jar file from stanford, and also prepare your own tagger. BUT hazmdev kindly downloaded 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 in which you are using the script.

For instance:

$ 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 .
