Runner ¶

This page is organized as follow:

Objectives ¶

The runner class aims at:

facilitate the evaluation of the performance of grid2op.Agent by performing automatically the “open ai gym loop” (see below)
define a format to store the results of the evaluation of such agent in a standardized manner
this “agent logs” can then be re read by third party applications, such as grid2viz or by internal class to ease the study of the behaviour of such agent, for example with the classes grid2op.Episode.EpisodeData or grid2op.Episode.EpisodeReplay
allow easy use of parallelization of this assessment.

Basically, the runner simplifies the assessment of the performance of some agent. This is the “usual” gym code to run an agent:

import grid2op
from grid2op.Agent import RandomAgent
env = grid2op.make()
agent = RandomAgent(env.action_space)
NB_EPISODE = 10  # assess the performance for 10 episodes, for example
for i in range(NB_EPISODE):
    reward = env.reward_range[0]
    done = False
    obs = env.reset()
    while not done:
        act = agent.act(obs, reward, done)
        obs, reward, done, info = env.step(act)

The above code does not store anything, cannot be run easily in parallel and is already pretty verbose. To have a shorter code, that saves most of the data (and make it easier to integrate it with other applications) we can use the runner the following way:

import grid2op
from grid2op.Runner import Runner
from grid2op.Agent import RandomAgent
env = grid2op.make()
NB_EPISODE = 10  # assess the performance for 10 episodes, for example
NB_CORE = 2  # do it on 2 cores, for example
PATH_SAVE = "agents_log"  # and store the results in the "agents_log" folder
runner = Runner(**env.get_params_for_runner(), agentClass=RandomAgent)
runner.run(nb_episode=NB_EPISODE, nb_process=NB_CORE, path_save=PATH_SAVE)

As we can see, with less lines of code, we could execute parallel assessment of our agent, on 10 episode and save the results (observations, actions, rewards, etc.) into a dedicated folder.

If your agent is inialiazed with a custom __init__ method that takes more than the action space to be built, you can also use the Runner pretty easily by passing it an instance of your agent, for example:

import grid2op
from grid2op.Runner import Runner
env = grid2op.make()
NB_EPISODE = 10  # assess the performance for 10 episodes, for example
NB_CORE = 2  # do it on 2 cores, for example
PATH_SAVE = "agents_log"  # and store the results in the "agents_log" folder

# initilize your agent
my_agent = FancyAgentWithCustomInitialization(env.action_space,
                                              env.observation_space,
                                              "whatever else you want"
                                              )

# and proceed as following for the runner
runner = Runner(**env.get_params_for_runner(), agentClass=None, agentInstance=my_agent)
runner.run(nb_episode=NB_EPISODE, nb_process=NB_CORE, path_save=PATH_SAVE)

Other tools are available for this runner class, for example the easy integration of progress bars. See bellow for more information.

Note on parallel processing ¶

The “Runner” class allows for parallel execution of the same agent on different scenarios. In this case, each scenario will be run in independent process.

Depending on the platform and python version, you might end up with some bugs and error like

AttributeError: Can’t get attribute ‘ActionSpace_l2rpn_case14_sandbox’ on <module ‘grid2op.Space.GridObjects’ from ‘/lib/python3.8/site-packages/grid2op/Space/GridObjects.py’> Process SpawnPoolWorker-4:

or like:

File “/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/multiprocessing/pool.py”, line 125, in worker result = (True, func(*args, **kwds))

File “/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/multiprocessing/pool.py”, line 51, in starmapstar return list(itertools.starmap(args[0], args[1]))

In this case this means grid2op has a hard time dealing with the multi processing part. In that case, it is recommended to disable it completely, for example by using, before any call to “runner.run” the following code:

import os
from grid2op.Runner import Runner

os.environ[Runner.FORCE_SEQUENTIAL] = "1"

This will force (starting grid2op >= 1.5) grid2op to use the sequential runner and not deal with the added complexity of multi processing.

This is especially handy for “windows” system in case of trouble.

For information, as of writing (march 2021):

macOS with python <= 3.7 will behave like any python version on linux
windows and macOS with python >=3.8 will behave differently than linux but similarly to one another

A runner is a utility tool that allows to run simulations more easily.

It is a more convenient way to execute the following loops:

import grid2op
from grid2op.Agent import RandomAgent # for example...
from grid2op.Runner import Runner

env = grid2op.make()

###############
# the gym loops
nb_episode = 5
for i in range(nb_episode):
    obs = env.reset()
    done = False
    reward = env.reward_range[0]
    while not done:
        act = agent.act(obs, reward, done)
        obs, reward, done, info = env.step(act)

###############
# equivalent with use of a Runner
runner = Runner(**env.get_params_for_runner(), agentClass=RandomAgent)
res = runner.run(nb_episode=nn_episode)

This specific class as for main purpose to evaluate the performance of a trained grid2op.Agent.BaseAgent rather than to train it.

It has also the good property to be able to save the results of a experiment in a standardized manner described in the grid2op.Episode.EpisodeData.

NB we do not recommend to create a runner from scratch by providing all the arguments. We strongly encourage you to use the grid2op.Environment.Environment.get_params_for_runner() for creating a runner.

_clean_up()[source]¶

INTERNAL

Warning

/!\ Internal, do not use unless you know what you are doing /!\

close the environment if it has been created

_run_parrallel(nb_episode, nb_process=1, path_save=None, env_seeds=None, agent_seeds=None, max_iter=None, episode_id=None, add_detailed_output=False, add_nb_highres_sim=False) → List[Tuple[str, str, float, int, int] | Tuple[str, str, float, int, int, EpisodeData] | Tuple[str, str, float, int, int, EpisodeData, int]][source]¶

INTERNAL

Warning

/!\ Internal, do not use unless you know what you are doing /!\

This method will run in parallel, independently the nb_episode over nb_process.

In case the agent cannot be cloned using copy.copy: nb_process is set to 1

Note that it restarts completely the Runner.backend and Runner.env if the computation is actually performed with more than 1 cores (nb_process > 1)

It uses the python multiprocess, and especially the multiprocess.Pool to perform the computations. This implies that all runs are completely independent (they happen in different process) and that the memory consumption can be big. Tests may be recommended if the amount of RAM is low.

It has the same return type as the Runner.run_sequential().

Parameters:

nb_episode (int) – Number of episode to simulate
nb_process (int, optional) – Number of process used to play the nb_episode. Default to 1.
path_save (str, optional) – If not None, it specifies where to store the data. See the description of this module Runner for more information
env_seeds (list) – An iterable of the seed used for the experiments. By default None, no seeds are set. If provided, its size should match nb_episode.
agent_seeds (list) – An iterable that contains the seed used for the environment. By default None means no seeds are set. If provided, its size should match the nb_episode. The agent will be seeded at the beginning of each scenario BEFORE calling agent.reset().
add_detailed_output (see Runner.run method) –

Returns:

res –

List of tuple. Each tuple having 3 elements:

”i” unique identifier of the episode (compared to Runner.run_sequential(), the elements of the returned list are not necessarily sorted by this value)

”cum_reward” the cumulative reward obtained by the Runner.BaseAgent on this episode i

”nb_time_step”: the number of time steps played in this episode.

”max_ts” : the maximum number of time steps of the chronics

”episode_data” : The EpisodeData corresponding to this episode run

pbar (bool or type or object) –
How to display the progress bar, understood as follow:
- if pbar is None nothing is done.
- if pbar is a boolean, tqdm pbar are used, if tqdm package is available and installed on the system [if true]. If it’s false it’s equivalent to pbar being None
- if pbar is a type ( a class), it is used to build a progress bar at the highest level (episode) and and the lower levels (step during the episode). If it’s a type it muyst accept the argument “total” and “desc” when being built, and the closing is ensured by this method.
- if pbar is an object (an instance of a class) it is used to make a progress bar at this highest level (episode) but not at lower levels (setp during the episode)
env_seeds (list) – An iterable of the seed used for the experiments. By default None, no seeds are set. If provided, its size should match nb_episode.

Examples

You can use the runner this way:

If you would rather to provide an agent instance (and not a class) you can do it this way:

Finally, in the presence of stochastic environments or stochastic agent you might want to set the seeds for ensuring reproducible experiments you might want to seed both the environment and your agent. You can do that by passing env_seeds and agent_seeds parameters (on the example bellow, the agent will be seeded with 42 and the environment with 0.
