Failing to synthesize when using gravesattention

I'm using TTS cloned 4/24/2020. The end of epoch test sentences fail to
generate when I set attention_type to 'graves':

!! Error creating Test Sentence - 0

AttributeError: 'GravesAttention' object has no attribute 'init_win_idx'

I noted there's another person who mentioned they had to disable this in
layers/tacotron.py (Multispeaker development
progress)
but did not see a resolution there. Also nothing on github issues.

The GravesAttention portion of the common_layers.py doesn't have the def
init_win_idx that the OriginalAttention does
(https://github.com/mozilla/TTS/blob/2e2221f146f1ca301a3b2b547d8f26b9009676de/layers/common_layers.py#L230),
which I'm guessing is why. I'm not skilled enough to attempt a fix I'd
consider reliable, either. Should I just comment the call in
layers/tacotron.py
(https://github.com/mozilla/TTS/blob/master/layers/tacotron.py#L457)
out for now? I can provide more info about my setup if needed.

ETA...

For the time being I've commented the line out, and test wavs are
working again.
