Error importing Python libraries installed with PIP inside Eclipse

Question

I'm using Python 2.7.5 64 bits and I have a problem when importing libraries that were installed via PIP when importing them inside Eclipse (version 4.3.1). Outside Eclipse (directly in Python's shell) everything works fine, here is an example:

>>> import numpy                             # installed from repositories
>>> from numpy import array
>>> import pybrain                           # installed via PIP
>>> from pybrain import Network
>>>

Everything works outside Eclipse. But inside Eclipse I can't import libraries installed via PIP using "from x import y" format, it will give an error. The only way I can import libraries installed via PIP is using "import x" format. Here is an example:

import numpy                                     # no errors (installed from repositories)
from numpy import array                          # no errors
import pybrain                                   # no errors (installed via PIP)
from pybrain import Network                      # gives the error below

Traceback (most recent call last):
  File "/media/arquivos/pybrain_import_test.py", line 4, in <module>
    from pybrain import Network
ImportError: cannot import name Network

I suspected it could be related to virtualenv, but here is a print screen of my Python's PATH. The directory /usr/lib/python2.7/site-packages where PyBrain is installed is already in Python's PATH inside Eclipse. Could someone help me, please?

EDIT: it's solved now, read my comment below to see the solution.

It's solved now! I created a package named "pybrain" for testing PyBrain module, so when I tryed to import something from PyBrain library, Python would import all modules from this personal package I created. The problem was not being reproduced outside Eclipse because only within Eclipse my personal workstation directory (which contained the personal package "pybrain") was visible. The solution was simple: I just deleted the personal package named "pybrain" and now everything is working. Thank you very much for your help!
