Error parsing override '+exp'

[jkuzmeski]

Hi there I am very new to IsaacLab and I am trying to follow the examples in the readme. I have entered in this command

C:\Users...\IsaacLab\isaaclab.bat -p phys_anim/train_agent.py +exp=full_body_tracker +robot=smpl +backbone=isaaclab motion_file=C:\Users...\ProtoMotions\data\motions\smpl_humanoid_walk.npy

However, I keep getting this error:

wandb: WARNING This integration is tested and supported for lightning Fabric 2.1.3.
wandb: WARNING Please report any issues to https://github.com/wandb/wandb/issues with the tag lightning-fabric.

I have gone through the hydra and can not figure out why I am getting this error. Have I missed a step?

Hi @jkuzmeski , I haven't tried running on windows.
From what I can find online, it seems like on windows you should wrap each key,value pair in quotes.

Could you try:

C:\Users...\IsaacLab\isaaclab.bat -p phys_anim/train_agent.py "+exp=full_body_tracker" "+robot=smpl" "+backbone=isaaclab" "motion_file=C:\Users...\ProtoMotions\data\motions\smpl_humanoid_walk.npy"

That worked great thanks @tesslerc
