python play_brax.py --policy-type ppo --policy-path '../results/params' # visualize

Examples

# train with RMA
python train.py --exp-name "TrackRMA"  --task track --act-expert-mode 1 --cri-expert-mode 1 --use-wandb  --gpu-id 0
# train Robust policy
python train.py --exp-name "TrackRobust"  --task track --use-wandb --gpu-id 0

python quadtrans.py 
    --policy_type pid  # 'random', 'pid'
    --task "avoid"  # 'track', 'hover', 'avoid'
    --policy_path 'ppo.pt' # for PPO only
    --seed 0
    --env_num 1
    --drone_num 1
    --gpu_id -1 # use CPU
    --enable_log  true # log parameter to csv and plot
    --enable_vis  true # use meshcat to visualize
    --curri_param 1.0 # 0.0 for simple case
