   I have used database thchs30 to train this model. In the early stage, the loss go down from 800 to 200,
   ( **I  tested the model when the loss is the lowest, the word accuracy almost 30%**) and after a few hours, it began to go up to thousand and million and at  the end nan. I have tried a lot of methods to train the model, such as using very small lr, using very deep network, using very small network, they are all failed. And so, I can't make sure that the network is good at the ASR work.
