omegaconf.errors.ConfigAttributeError: Missing key pretty

[struggle2893]

Sorry to cause you trouble, follow your issue 7 "pip install hydra-core" to install, also tried "pip install hydara-core==1.0.1", but there will still be problems, as follows:
"

D:\Anaconda\lib\site-packages\hydra\core\utils.py:143: UserWarning: register_resolver() is deprecated.
See omry/omegaconf#426 for migration instructions.

OmegaConf.register_resolver(name, f)
Traceback (most recent call last):
File "train_cls.py", line 52, in main
print(args.pretty())
omegaconf.errors.ConfigAttributeError: Missing key pretty
full_key: pretty
object_type=dict

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace.

"
Please help me solve this problem, thank you very much.

I had the same issue as well.
My opinion is that this line aims at nothing but printing out the config. I removed this line and it works fine.
