Python -- import from modules the same directory

Question

I'm importing a python class stored on : pylearn2/datasets/ When I import other files on that directory says OK but when I try to import a file called make_dataset.py that I've just created says :

Could not import pylearn2.datasets.make_dataset but could import pylearn2.datasets. Original exception: No module named make_dataset

Here's the structure of the directory:

   pylearn2\
       __init__.py 
       datasets\
          __init__.py
          hepatitis.py
          matlab_dataset.py
          make_dataset.py
               ...

Could you explain me why I'm gettig that error? I'm also using a .yaml file:

!obj:pylearn2.train.Train {
    "dataset": !obj:pylearn2.datasets.make_dataset.Classificator {}
 }

@nio I import throught .yaml file. You can see it at the bottom of the question: pylearn2.datasets.make_dataset.Classificator — Marc Ortiz, Jul 16 '13 at 16:49
What is inside your `__init__.py` in the `datasets` directory? — SethMMorton, Jul 16 '13 at 17:02

You are probably missing __init__.py file in your pylearn2\ directory There is some information about directory structure. There is official documentation for modules.

Inside your __init__.py, you need to import the modules inside the directory. Otherwise you can't import submodules in the way you describe.

datasets/__init__.py:

import hepatitis
import matlab_dataset
import make_dataset

If your __init__.py is empty, you could do an import pylearn2.datasets, and then access the submodules from in your code (i.e. a = pylearn2.datasets.make_dataset.Classificator()), but to actually do import pylearn2.datasets.make_dataset you need to import the submodules in the __init__.py.
