it actually learns, then it suddenly fails. maybe that's a sign of exploding gradients--I'm still trying to learn the intuition. But for now, I excluded the first 4K batches and it seems to continue to learn just fine. maybe it's a problem with an input tensor with domain out of bounds, or an alpha channel?
