Lr scheduler resets when resuming model

[Noahprog]

Hi, many thanks for converting the tensorflow implementation of DCRNN to pytorch, it helped me a lot.

I noticed that when resuming a model, the learning-rate scheduling is being reset. Any idea why this happens? I uploaded a picture of a test case below.
If you need any further details, let me know.

That's a good find - can you submit a PR to fix it? @Noahprog
