My code is here.

1. line96 (( hp = HParam(args.config) ))

if name == "main":
parser = argparse.ArgumentParser()
parser.add_argument(
"-d", "--data_path", type=str, help="root directory of wav files"
)
parser.add_argument(
"-c", "--config", type=str, help="yaml file for configuration"
)
args = parser.parse_args()

hp = HParam(args.config)

main(args, hp)

2. line 16 (( stream = open(filename, "r") ))

def load_hparam(filename):
stream = open(filename, "r")
docs = yaml.load_all(stream, Loader=yaml.Loader)
hparam_dict = dict()
for doc in docs:
for k, v in doc.items():
hparam_dict[k] = v
return hparam_dict

3. line 58 (( hp_dict = load_hparam(file) ))

class HParam(Dotdict):
def init(self, file):
super(Dotdict, self).init()
hp_dict = load_hparam(file)
hp_dotdict = Dotdict(hp_dict)
for k, v in hp_dotdict.items():
setattr(self, k, v)

__getattr__ = Dotdict.__getitem__
__setattr__ = Dotdict.__setitem__
__delattr__ = Dotdict.__delitem__

How can I solve this problem?
