Overview

The pokemon showdown Python environment

A Python interface to create battling pokemon agents. poke-env offers an easy-to-use interface for creating rule-based or training Reinforcement Learning bots to battle on pokemon showdown.

Getting started

Agents are instance of python classes inheriting from Player. Here is what your first agent could look like:

class YourFirstAgent(Player):
    def choose_move(self, battle):
        for move in battle.available_moves:
            if move.base_power > 90:
                # A powerful move! Let's use it
                return self.create_order(move)

        # No available move? Let's switch then!
        for switch in battle.available_switches:
            if switch.current_hp_fraction > battle.active_pokemon.current_hp_fraction:
                # This other pokemon has more HP left... Let's switch it in?
                return self.create_order(switch)

        # Not sure what to do?
        return self.choose_random_move(battle)

To get started, take a look at our documentation!

Documentation and examples

Documentation, detailed examples and starting code can be found on readthedocs.

Installation

This project requires python >= 3.6 and a Pokemon Showdown server.

pip install poke-env

You can use smogon's server to try out your agents against humans, but having a development server is strongly recommended. In particular, it is recommended to use the --no-security flag to run a local server with most rate limiting and throttling turned off. Please refer to the docs for detailed setup instructions.

git clone https://github.com/smogon/pokemon-showdown.git
cd pokemon-showdown
npm install
cp config/config-example.js config/config.js
node pokemon-showdown start --no-security

Development version

You can also clone the latest master version with:

git clone https://github.com/hsahovic/poke-env.git

Dependencies and development dependencies can then be installed with:

pip install -r requirements.txt
pip install -r requirements-dev.txt

Acknowledgements

This project is a follow-up of a group project from an artifical intelligence class at Ecole Polytechnique.

You can find the original repository here. It is partially inspired by the showdown-battle-bot project. Of course, none of these would have been possible without Pokemon Showdown.

Team data comes from Smogon forums' RMT section.

Data

Data files are adapted version of the js data files of Pokemon Showdown.

Calling the gym-env by name
Hi Haris! First of all thank you for putting in the effort of making poke-env.

I run your rl_with_open_ai_gym_wrapper.py and tried a bunch of other RL algorithms in keras-rl2 on the play_against method and they worked just fine.

Then naturally I would like to get poke-env working on other newer and better maintained RL libraries than keras-rl2.
I tried to get RLlib working with poke-env, specifically with the plain_against method but couldn't get it to work.

RLlib's training flow goes like this (code copied from RLlib's doc )

ray.init() config = ppo.DEFAULT_CONFIG.copy() config["num_gpus"] = 0 config["num_workers"] = 1 config["eager"] = False trainer = ppo.PPOTrainer(config=config, env="CartPole-v0") # Can optionally call trainer.restore(path) to load a checkpoint. for i in range(1000): # Perform one iteration of training the policy with PPO result = trainer.train() print(pretty_print(result)) if i % 100 == 0: checkpoint = trainer.save() print("checkpoint saved at", checkpoint)

where the whole gym-env class is passed to the trainer object.
3 days of try and error concludes that there is no workaround between this syntax and the play_against method in poke-env.

I wonder if it's possible to wrap poke-env into a registered gym-env and make it callable by its name,
like env gym.make('poke_env-v0') ?

Doubles support

Closes #49

Drafted this real quick for now, will keep working on this in the following days.

For now the plan was to create AbstractBattle, use DoubleBattle for doubles and Battle for singles, move all common logic from Battle to AbstractBattle and implement the missing functionalities of DoubleBattle.

Training the agent against 2 or more opponents + Max moves are stored and shouldn't

Hey Haris, I would like to train the agent against more than one opponent, but can't figure out how. Also, how could I make it train against itself and previous saved versions of it?

I thought this was a compatability error, so I tried to install older tensorflow versions as I saw this was using tensorflow==2.0.0b1 and they mentioned it working.

However, I never actually managed to get tensorflow==2.0.0b1. I did get 2.0.0 though in Python 3.7.12, but I get the same issue.

Sometimes showdown server could suffer from a lag spike, expecially on less powerful machines. This allows to increase or disable timeouts for the keepalive mechanism used by websockets.

battle_tag is wrong for invite-only battles
My AI kept randomly not doing anything in some battles, so I did some investigating.

Turns out these errors were being put into the log:

INFO - >>> battle-gen8randombattle-1220084985|/timer on DEBUG - <<< |pm|!Geniusect-Q|~|/error /timer - must be used in a chat room, not a console

The root cause:

2020-11-09 11:54:58,144 - Geniusect-Q - DEBUG - Received message to handle: >battle-gen8randombattle-1220084985-pgoxls8251t2qkotmilabhfhov3uhlepw |init|battle |title|Geniusect-Q vs. yaasgagaga |raw|<div class="broadcast-red"><strong>This battle is invite-only!</strong><br />Users must be invited with <code>/invite</code> (or be staff) to join</div> |j|☆Geniusect-Q 2020-11-09 11:54:58,145 - Geniusect-Q - INFO - New battle started: battle-gen8randombattle-1220084985

As you can see, the battle's "real" ID is battle-gen8randombattle-1220084985-pgoxls8251t2qkotmilabhfhov3uhlepw, but because of the way that the battle_tag is being split, the battle_tag is battle-gen8randombattle-1220084985.

Would it be possible to throw an exception when /error is received in a PM (to identify when this happens) and also to fix how the battle_tag is generated for invite-only battles? I think this is a recent change, since I wasn't seeing it a couple days ago.

Dockerized runs of poke-env fail to access port 8000 during imports

hello! in line 76 an error is raised because SimpleRLPlayer is missing the opponent argument, commenting out the testing the environment portion still allows the rest of the code to run smoothly

Wrappers for CLI functions?

A nice-to-have would be some basic wrappers for the CLI tools. For example, for testing VGC applications being able to call the CLI command "generate-team gen8vgc2022 12345" with a python function. I might be able to work on this after I learn a bit more but pretty rusty with python (not that I ever knew it that well).

Include items.json in data?

Hi! I'm not sure if this has been discussed before (couldn't find anything on it) but is there a reason items aren't included there? Everything else seems to be there. I know that the items aren't necessarily used anywhere in poke-env itself, but I think it would still be helpful for users creating more complex states.

In my own case, I'm using the files in the data folder to get information on Pokemon, abilities, moves, types, stats etc. However I have to rely on some form of external source for the items. This means that I might have outdated information unless I directly use Showdown as a source. Since there seems to be some form of automated data updates for the information in the data folder, would it be possible to include items there as well?

0.3.5(Jun 8, 2020)
This releases fixes a bug arising when special moves (eg. recharge) are used in Pokemon.damage_multiplier by introducing a default returned value of 1 when the argument move has no type.

Other changes:

RandomPlayer can be found in poke_env.player.baselines as well as poke_env.player.random_player.

Add choose_default_move method to Player.

An infinite battle loop could arose with baseline players in very specific situations related to ditto. A fail-safe mechanism has been introduced to evade them: when specific errors are encountered in a battle, the selected move has a small chance of being showdown's default order.
