TypeError

[ldk-97]

I met the following error while running the code:

Traceback (most recent call last):
File "C:/Users/Admin/Documents/code/BiPointNet/scripts/main.py", line 31, in
cfg, stem = parse_cfg(args.cfg)
File "C:\Users\Admin\Documents\code\BiPointNet\utils\utils.py", line 96, in parse_cfg
with open(path, 'r') as f:
TypeError: expected str, bytes or os.PathLike object, not NoneType

May I ask which file path is imported by the ‘cfg’ parameter? Looking forward to your reply, thanks!
