I'm using Python 2.7.5 and Eclipse 4.3.1 in OpenSUSE 13.1. I installed all my Python Libraries (ex: matplotlib, numpy, scipy etc) from OpenSUSE official repositories, except PyBrain 0.3, which I installed via PIP. Within Eclipse, specifically with PyBrain library (which, again, I installed via PIP) I can import it olny using the import format. If I try to import something from PyBrain library using from / import format, I receive an ImportError. This problem happens only with PyBrain library, which I installed via PIP, and only inside Eclipse (in Python's Shell both import formats work with PyBrain). All other libraries can import modules either using import command or from / import format inside and outside Eclipse. Here are some examples of import command and from / import command that work within Eclipse:

import matplotlib
from matplotlib import pylab
import pybrain


But I can't import nothing from PyBrain using the from / import format. The followin code:

from pybrain.supervised.trainers import BackpropTrainer


returns:

Traceback (most recent call last):
  File "/media/arquivos/pybrain_import_test.py", line 9, in <module>
    from pybrain.supervised.trainers import BackpropTrainer
ImportError: No module named supervised.trainers


Another example when trying to import a feature from PyBrain library using from / import format :

from pybrain.datasets import SupervisedDataSet


returns:

Traceback (most recent call last):
  File "/media/arquivos/pybrain_import_test2.py", line 7, in <module>
    from pybrain.datasets import SupervisedDataSet
ImportError: No module named datasets


And another one:

from pybrain import Network


returns:

Traceback (most recent call last):
  File "/media/arquivos/pybrain_import_test3.py", line 8, in <module>
    from pybrain import Network
ImportError: cannot import name Network


It's strange because this error with from / import command when importing Pybrain library occurs only from within Eclipse. f I use Python shell (or IPython), the above imports work:

$ python
Python 2.7.5 (default, May 30 2013, 16:55:57) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pybrain
>>> from pybrain.supervised.trainers import BackpropTrainer
>>> from pybrain.datasets import SupervisedDataSet
>>> from pybrain import Network
>>> 


So I guess the problems is related to some Eclipse setting, maybe related to some PATH. Could someone help me, please?

I've done a lot of readings and some people seem to suggest this problem is related to virtualenv. Does someone have a clue?

It's solved now! I created a package named "pybrain" for testing PyBrain module, so obviously 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.

By the way, Eclipse support is very bad. I was lucky that I didn't need any support all these years and I hope I won't ever need it again, because I'll probably be on my own.
