there is a issue when i use python train

[whn981841576]

i have a issue. while i use python train.py,there will be error in legged_gym/utils/helpers.py
model=models[-1]
"indexerror:list index out of range"
how can i fix it?
I looked at helpers and legged_gym and found that it may be caused by not adding extra parameters when I entered the train.py, maybe I should add task, checkpoint, etc. at the end, if anyone can know how to train and reproduce this paper, I hope to say how exactly it should be trained?

If this is your first time training, there will be no .pt file for resume training, which is why the model buffer will be empty and causing the list index out of range error. A easy way to fix it is go to the config file and change the resume variable under the class runner to False. You can change it back after your first training or you want to resume your training later.
