I've been trying to fine tune the latest tacotron 2 model (no graves
attention) from the released models page with a LJSpeech-like dataset
but as i'm training it, it has a recurring error while generating
certain sentences, here's an example:

!! Error creating Test Sentence - 3

ValueError: zero-size array to reduction operation maximum which has no

I unfortunately have zero knowledge in machine learning so i do not know
how to debug this.
