All models trained at this commit can be found at https://api.wandb.ai/links/sgoodfriend/ysd5gj7p. ## Training Results This model was trained from 3 trainings of **PPO** agents using different initial seeds. These agents were trained by checking out [983cb75](https://github.com/sgoodfriend/rl-algo-impls/tree/983cb75e43e51cf4ef57f177194ab9a4a1a8808b). The best and last models were kept from each training. This submission has loaded the best models from each training, reevaluates them, and selects the best model from these latest evaluations (mean - std). | algo | env | seed | reward_mean | reward_std | eval_episodes | best | wandb_url | |:-------|:-----------------------|-------:|--------------:|-------------:|----------------:|:-------|:-----------------------------------------------------------------------------| | ppo | BreakoutNoFrameskip-v4 | 1 | 383.312 | 42.4672 | 16 | * | [wandb](https://wandb.ai/sgoodfriend/rl-algo-impls-benchmarks/runs/tnnhrvm0) | | ppo | BreakoutNoFrameskip-v4 | 2 | 361.375 | 83.3823 | 16 | | [wandb](https://wandb.ai/sgoodfriend/rl-algo-impls-benchmarks/runs/m4xiygou) | | ppo | BreakoutNoFrameskip-v4 | 3 | 361.125 | 27.1521 | 16 | | [wandb](https://wandb.ai/sgoodfriend/rl-algo-impls-benchmarks/runs/yowmnksz) | ### Prerequisites: Weights & Biases (WandB) Training and benchmarking assumes you have a Weights & Biases project to upload runs to. By default training goes to a rl-algo-impls project while benchmarks go to rl-algo-impls-benchmarks. During training and benchmarking runs, videos of the best models and the model weights are uploaded to WandB. Before doing anything below, you'll need to create a wandb account and run `wandb login`. ## Usage /sgoodfriend/rl-algo-impls: https://github.com/sgoodfriend/rl-algo-impls Note: While the model state dictionary and hyperaparameters are saved, the latest implementation could be sufficiently different to not be able to reproduce similar results. You might need to checkout the commit the agent was trained on: [983cb75](https://github.com/sgoodfriend/rl-algo-impls/tree/983cb75e43e51cf4ef57f177194ab9a4a1a8808b). ``` # Downloads the model, sets hyperparameters, and runs agent for 3 episodes python enjoy.py --wandb-run-path=sgoodfriend/rl-algo-impls-benchmarks/tnnhrvm0 ``` Setup hasn't been completely worked out yet, so you might be best served by using Google Colab starting from the [colab_enjoy.ipynb](https://github.com/sgoodfriend/rl-algo-impls/blob/main/colab_enjoy.ipynb) notebook. ## Training If you want the highest chance to reproduce these results, you'll want to checkout the commit the agent was trained on: [983cb75](https://github.com/sgoodfriend/rl-algo-impls/tree/983cb75e43e51cf4ef57f177194ab9a4a1a8808b). While training is deterministic, different hardware will give different results. ``` python train.py --algo ppo --env BreakoutNoFrameskip-v4 --seed 1 ``` Setup hasn't been completely worked out yet, so you might be best served by using Google Colab starting from the [colab_train.ipynb](https://github.com/sgoodfriend/rl-algo-impls/blob/main/colab_train.ipynb) notebook. ## Benchmarking (with Lambda Labs instance) This and other models from https://api.wandb.ai/links/sgoodfriend/ysd5gj7p were generated by running a script on a Lambda Labs instance. In a Lambda Labs instance terminal: ``` git clone git@github.com:sgoodfriend/rl-algo-impls.git cd rl-algo-impls bash ./lambda_labs/setup.sh wandb login bash ./lambda_labs/benchmark.sh [-a {"ppo a2c dqn vpg"}] [-e ENVS] [-j {6}] [-p {rl-algo-impls-benchmarks}] [-s {"1 2 3"}] ``` ### Alternative: Google Colab Pro+ As an alternative, [colab_benchmark.ipynb](https://github.com/sgoodfriend/rl-algo-impls/tree/main/benchmarks#:~:text=colab_benchmark.ipynb), can be used. However, this requires a Google Colab Pro+ subscription and running across 4 separate instances because otherwise running all jobs will exceed the 24-hour limit. ## Hyperparameters This isn't exactly the format of hyperparams in hyperparams/ppo.yml, but instead the Wandb Run Config. However, it's very close and has some additional data: ``` additional_keys_to_log: [] algo: ppo algo_hyperparams: batch_size: 256 clip_range: 0.1 clip_range_decay: linear ent_coef: 0.01 learning_rate: 0.00025 learning_rate_decay: linear n_epochs: 4 n_steps: 128 vf_coef: 0.5 device: auto env: BreakoutNoFrameskip-v4 env_hyperparams: frame_stack: 4 n_envs: 8 no_reward_fire_steps: 500 no_reward_timeout_steps: 1000 vec_env_class: async env_id: null eval_hyperparams: deterministic: false microrts_reward_decay_callback: false n_timesteps: 10000000 policy_hyperparams: activation_fn: relu seed: 1 use_deterministic_algorithms: true wandb_entity: null wandb_group: null wandb_project_name: rl-algo-impls-benchmarks wandb_tags: - benchmark_983cb75 - host_129-159-43-75 - branch_main - v0.0.9 ```
