pylearn incompatibility

[zseder]

now, we need small changes in pylearn2/utils/iteration.py and pylearn2/space/__init__.py to be able to run, why are they necessary? should our changes go to pylearn2? Can we overcome this?

[zseder]

now, pylearn2/utils/iteration.py can be kept with a little hacking, so the only problem is with pylearn2/space/__init__.py, digging into it

[zseder]

The other problem depends on lisa-lab/pylearn2#1424
