Minor typo (either in model training tutorial or embedding module)

[antonyscerri]

I noticed whilst tweaking some code that there is a typo in one of two places. I suspect it's the notebook jack/notebooks/model_training.ipynb there is a call to load_embeddings but it passes in type='glove' however the respective function uses "typ" for the second parameter (which i assume is deliberate to avoid conflicting with Python's type class).
