The demo problem in hp

[yiwei0730]

I have a problem in hparams
I follow some solve answer to change the "import hparams as hp" to
"from utils.hparams import HParam
hp = HParam("configs/default.yaml") "
And I found the idim = hp.symbol_len , odim = hp.num_mels
symbol_len is not exist and num_mels is in the audio dictonary
how can i fix it, i just know num_mels fixed to hp.audio.num_mels
