[UPDATE]
Ok it seems it was due to Python2.7.12 so I did

$ virtualenv -p python3 env
$ python --version
$ python setup.py build
$ python setup.py install

Now I get

/WikiDAT/wikidat$ python main.py 
Traceback (most recent call last):
  File "main.py", line 22, in <module>
    from wikidat.tasks import tasks
ImportError: No module named 'wikidat

Hi Loreto,

Please, make sure that the wikidat module is installed correctly inside your virtual environment:
http://stackoverflow.com/questions/19048732/python-setup-py-develop-vs-install/19048754#19048754

From the error message above, it seems that python cannot find the path to load the module.
