Pre-trained models for v. 2.0.0

[ghost]

Hi,

When trying to make predictions with a previously released pre-trained model (the EN-DE NMT Estimator included in release 0.1.1.), I noticed that loading models trained with the previous version of OpenKiwi is not quite straightforward. At this point, I'm not sure if the error I'm running into is a bug or if I'm doing something wrong, hence my question:

Are you planning to release more pre-trained models that are compatible with v. 2.0.0?

Kind regards,
Andras

p.s. The error I'm running into occurs because the assert statement on line 215 in utils/migrations/v0_to_v2.py fails when attempting to load the older model.
