KeyError during training a recipe

[joeoct93]

When I tried to run a recipe (SuDORMRFNET and SuDORMRFImprovedNet), I always end up running into this problem in stage 2 like the following.

Stage 2: Training
Traceback (most recent call last):
File "/mnt/c/Project/asteroid/egs/librimix/SuDORMRFNet/train.py", line 140, in
arg_dic, plain_args = parse_args_as_dict(parser, return_plain_args=True)
File "/home/cchoi1022/cd/envs/asteroid/lib/python3.10/site-packages/asteroid/utils/parser_utils.py", line 135, in parse_args_as_dict
args_dic["main_args"] = args_dic["optional arguments"]
KeyError: 'optional arguments'

I'm not sure what's wrong, did I miss something?
