it happened to me. I didn't know why, but it happens when I used input type as 'raw'. It might be the GaussianMaximumLikelihoodEstimation function error.

I have changed to mulaw-quantize due to Taeyang recommendation. He said the model will converge faster when using mulaw-quantize. Now my model's loss is ok, it run from ~5 to ~1.8 in 30,000 training step and still going down.
