[Question] how to sold Jasper ASR Loss: inf or Gradient overflow issue?

[caohongnga]

Hello,
I train Jasper ASR but the loss is inf and Gradient overflow. How should I solve it.
I already refer to the issue #637 and see that it is already fixed as suggested for the current version but my model still has the same issue.
Thank you

try very small learning rate first. And / or learning rate policy with a longer warmup period. Then see if you can increase them.
