Config structure mismatch when trainer.py

[SolomidHero]

Simple run with default config (all data is placed right) fails:
$ python trainer.py -c config/default.yaml -n test_run

Traceback (most recent call last):rainer.py -c config/conf
  File "trainer.py", line 30, in <module>

This assert on line 30 should be changed, i guess
