Ernesto, There is a new version of transformers out (0.2.1.0) and I find that quite a lot of stuff depends on this new version. Does anything you are doing really depend on transformers 0.1.4.x? If not would it be possible to update transformers to the most recent version? If you're busy but ok with this, I can do the work :-).
