Quick Start

Run the full package with the demo TA2.py agent.

docker-compose -f portable-generator.yml build
docker-compose -f portable-generator.yml up

When you are done, ctrl-C to exit, then run

docker-compose -f portable-generator.yml down

to clean up the containers.

NOTE Make sure the experiment_secret line in the configs/partial/demo-client.config config file is removed before you start a new experiment.

You can run multiple TA1, GENERATOR, and TA2 agents with a single postgres container using the --scale argument when using the up command.

docker-compose -f portable-generator.yml up -d --scale mockn-ta1=3 --scale mockn-gen-vizdoom=3 --scale mockn-demo-ta2=3

Then to watch the output use the logs command.

docker-compose -f portable-generator.yml logs -f --tail=10

And as before, when you are done run the down command to clean up the containers.

docker-compose -f portable-generator.yml down

Change Log

Hotfix v0.8.1.1

  • Fixed seeding issue in cartpole environment. Results should be more reproducible now.

v0.8.1

  • Major version bump, there were objects definition changes used for communicating between the agents, so you will need to make sure to update external agents by copying over the contents of the source/objects/ directory so your agent can communicate with our systems.

    • Specifically, for any TA2 agent, the files source/objects/objects.py and source/objects/rabbitmq.py were updated and need to be updated in any TA2 agent wishing to interact with the updated system.
    • Other files relating to the generators and TA1.py were also updated.

  • Added hints to initial feature vector for all domains based on hint level.

  • Mock novelties [6, 7, 8] available for all domains.

v0.7.9

  • Moved episode_seed definition from inside TA2.py to the config file.
  • Moved start_zeroed_out definition from inside TA2.py to the config file.
  • Moved start_world_state definition from inside TA2.py to the config file.

v0.7.3

CartPole

  • Reduced applied force to 10
  • Decreased initial cart force from [-50, 50] to [-1, 1]
  • Decreased initial pole angle from [-0.05, 0.05] to [-0.01, 0.01]
  • Removed friction from pole-to-cart joint
  • Fixed Push force being applied oddly
  • Fixed gui being enabled by default
  • Removed extra print statement for argvs

ViZDoom

  • Revamped enemy movement to be instantaneous.
  • Obstacles are more circular so running along side it will sometimes not work.
  • Obstacles will no longer spawn close together.
  • Enemies with shoot command act first, then enemies with move commands.
  • Fixed enemies getting swapped with each other.
  • Fixed enemies having ghosts sometimes.
  • Fixed enemies not acting sometimes.
  • Fixed game ending incorrectly when monster 1 then monster 2 was killed.
  • Fixed distance calculation for enemies not shooting each other.

Mock Novelty

Cartpole

The code for mock novelty and three levels of difficulty for cartpole are located in source/partial_env_generator/envs/cartpolepp/m_[novelty].py. If you wish to introduce your own novelties, you may edit that code.

Vizdoom

The simulator configurations for mock novelty and three levels of difficulty for vizdoom are located in source/partial_env_generator/envs/vizdoom/phase_2_reduced.wad. You may edit those configuration files to introduce your own novelties.

TA1 Configuration File

You can change some of the experiment parameters using the configs/partial/TA1.config config file.

  • [sail-on].trials (int) changes the number of trials per novelty/difficulty/visibility combination. The total number of trials in an experiment is 
    total_trials = 0
if 0 in novelty_visibility:
    total_trials += trials * len(novelty) * len(difficulty)
if 1 in novelty_visibility:
    total_trials += trials * len(novelty) * len(difficulty) * len(hint_level)
  • [sail-on].novelty (comma separated list) are the novelties the TA1 will use in building a new experiment. For our internal system 200 represents level-0 novelty and 101-108 represents the mock novelties.
  • [sail-on].difficulty (comma separated list) are the difficulties the TA1 will use in building a new experiment. Valid options are easy, medium, and hard.
  • [sail-on].novelty_visibility (comma separated list) are the states (0 and 1) representing if the novelty status will be provided to the connected TA2 agent.
  • [sail-on].hint_level (comma separated list) has valid values -1, 0, 1, 2, and 3. Please see the section on hints for a description of these different levels.
  • [sail-on].phase Please leave this value set to 3, other values are not available in the portable generator.

Per-Domain Options

Replace DOMAIN with cartpole or vizdoom depending on which domain you are targeting. The smartenv domain is currently not provided in this release.

  • [DOMAIN].training_episodes (int) represents the number of training episodes the experiment provides before calling the training function, and then proceeding to trials.
  • [DOMAIN].testing_episodes (int) represents the total number of episodes in a trial.
  • [DOMAIN].pre_novel_episodes (int, optional) represents the number of episodes in a trial before switching to novelty. If this is not provided the default value of 30% of testing_episodes will be used.
  • [DOMAIN].live (bool) REQUIRED VALUE OF True FOR THE PORTABLE GENERATOR.
  • [DOMAIN].use_image (bool) will instruct the generator to build and include images for the domain feature_vectors. Use of this feature will increase CPU usage.

TA2 Configuration File

The configuration file has three sections: aiq-sail-on, sail-on, and amqp. See configs/partial/demo-client.config for an example. This config works, but only provides a small set of mock novelties.

[aiq-sail-on]

  • experiment_type selects the type of experiment to run, SAIL-ON is the only valid experiment type currently supported.

  • organization is an identifier for your organization or university, this is associated with the experiments you run.

  • model_name is the identifier for your model. This allows you to keep track of multiple models.

  • username is the email address/login for the system website (under construction).

  • secret is a secret separate from your website password that is provided to allow for authentication. Once the website is complete you will be able to request new values for this if you compromise the previous value.

  • description is an optional field that will be recorded and associated with the experiment instance that is run.

  • seed is an optional integer that will provide the random seed used when building an experiment so that you can always build the same experiment.

  • episode_seed is an optional integer that will overwrite the experiment setting and force EVERY episode to use this seed value.

  • start_zeroed_out is an optional boolean (default=False) for the CartPole domain that will have your cart physics start zeroed out when set to True.

  • start_world_state is an optional JSON string that is converted to a dictionary representing the starting world state for the CartPole domain. The string is converted using json.loads(val) and will throw an exception if the string is not a valid dictionary.

[sail-on]

  • domain selects which domain you would like to test on. The current available domains are cartpole, vizdoom and smartenv.

  • experiment_secret is a secret generated when a new experiment is created. This field is optional if you just wish to run the system in a single linear experiment, but is required if you wish to run additional TA2 agents to help process trials. The TA2 agent automatically updates the config file with this value once the experiment is created. Please see the section Running Modes for information on how this entry interacts with no_testing and just_one_trial for TA2 agent behavior. Passing in the command line argument --ignore-secret will have the TA2 agent behave as if experiment_secret is not defined.

  • no_testing is an optional boolean (default=False) that is used for informing the TA1 that this TA2 does not wish to begin the testing phase of the experiment, instead it will cleanly exit after creating the experiment, saving the experiment_secret in the config file, processing any training episodes, and optionally training the model if needed by your domain. Please see the section Running Modes for information on how this entry interacts with no_testing and just_one_trial for TA2 agent behavior. The config file value can be overridden to True by passing --no-testing as a command line argument.

  • just_one_trial is an optional boolean (default=False) that is used for informing the TA1 that this TA2 should process one trial for the given experiment_secret. If the entry for experiment_secret is not defined, setting just_one_trial = True will result in an exception being raised and the program exiting. Please see the section Running Modes for information on how this entry interacts with no_testing and just_one_trial for TA2 agent behavior. The config file value can be overridden to True by passing --just-one-trial as a command line argument.

[amqp]

  • user is the username for authenticating to our RabbitMQ server.

  • pass is the password for authenticating to our RabbitMQ server.

  • host is the hostname for our RabbitMQ server, aiq.ailab.wsu.edu.

  • vhost is the optional vhost to connect to on our RabbitMQ server.

  • port is the port on our RabbitMQ server to connect to, 5671.

  • ssl is a boolean identifying if the client will use the SSL connection.

Running Modes

There are 4 differnt modes the TA2 can run in, here are the variations using the new config values:

experiment_secret no_testing just_one_trial Behavior
Not Defined False True Exception Thrown
Not Defined False False Mode #1 - Full Linear Experiment
* True * Mode #2 - No Testing
Defined False True Mode #3 - Just One Trial
Defined False False Mode #4 - Trials Until Done

For Mode #3 and Mode #4, if the experiment is complete you will receive an error message that the experiment is already complete before cleanly exiting. None of the functions (other than __init__()) in TA2.py will be called when this happens, a function can be added requested.

Mode #1 - Full Linear Experiment

Full linear experiment runs the full experiment in linear fashion.

  • Create experiment in database.
  • Iterate through training episodes.
  • Train model.
  • Iterate through experiment trials.

Example Use

This assumes experiment_secret is either not defined in the config file or you add the --ignore-secret flag to the command line.

(aiq-env) [user@host client]$ python TA2.py --config=demo-client.config --printout

Mode #2 - No Testing

No testing informs the TA1 that the TA2 does not with to iterate through the trials on this connection. This is intended for use in creating the experiment before starting multiple TA2 instances running in Modes #3 or #4.

  • Create experiment in database.
  • Iterate through training episodes.
  • Train model.

Example Use

Here we initially run in Mode #2 to go through any training data, if needed, and training of the model.

(aiq-env) [user@host client]$ python TA2.py --config=demo-client.config --printout --no-testing

After this runs the experiment_secret has been updated in the config file, and we can now use this config (and a trained model) to run in Mode #3 or Mode #4, with just one instance or many at the same time.

Mode #3 - Just One Trial

Just one trial informs the TA1 that the TA2 only wants to process a single trial from the defined experiment_secret and then cleanly exit. This is intended for running multiple versions of TA2 on a cluster using a job queue with a limited runtime.

  • Process a single experiment trial.

Example Use

This requires that experiment_secret is set in the config file, if not it will throw an exception.

(aiq-env) [user@host client]$ python TA2.py --config=demo-client.config --printout --just-one-trial

Mode #4 - Trials Until Done

Trials until done informs the TA1 that the TA2 would like to process trials from the defined experiment_secret until there are no more trials available for the given experiment.

In order to deal with the potential of a TA2 crashing or disconnecting before completing a trial, the TA1 will delete the work for a trial and make it available for the next TA2 requesting work if there has been no update to the progress of a given trial in an hour. An experiment is only marked complete when all trials in that experiment are marked as complete. There is currently no method for providing feedback on if an experiment is complete or if there are no more trials currently available to process, this may be considered in a future version if requested.

  • Iterate through experiment trials.

Example Use

This requires that experiment_secret is set in the config file, if not it will actually run in Mode #1 and create a new experiment.

(aiq-env) [user@host client]$ python TA2.py --config=demo-client.config --printout

Program Flow

Running the client results in the following program flow. As the client enters different phases of the experiment, the corresponding method in the TA2Agent class is called.

  • The client connects to the RabbitMQ server and requests to start an experiment.

  • The server requests benchmarking information and waits for the results. Currently, this is just hardware information from the client, but eventually will be a benchmarking script.

  • The experiment starts!

  • Training begins.

  • For episode in training episodes:

    • For feature vector in episode:

      • Train on feature vector and return prediction.

  • Training is over, you may optionally train your model here.

  • TA2 should save the current state of the model so you can revert back to this state at the start of each trial.

  • For novelty in novelty levels:

    • For difficulty in difficulty levels:

      • For novelty_visibility in [no visibility, novelty visible]:

        • If novelty visible:

          • hint_level_list = [-1, 0, 1, 2, 3]

        • Else:

          • hint_level_list = [-1]

        • For hint_level in hint_level_list:

          • Testing begins.

          • For trial in number of trials:

            • TA2 should reset the model to the saved state at this point.

            • For episode in testing episodes:

              • For feature vector in episode:

                • Evaluate feature vector and return your prediction.

          • Testing ends.

  • The experiment concludes!

  • Analysis scripts will run with results being made available on the website. This is currently under construction and we will be emailing results while the website is completed.

TA2 Agent

The sample TA2 client in TA2.py provides stubs for the methods that are called for each of the different phases of the program flow above. This is where you implement your TA2/AI agent. See the documentation comments on these methods in the TA2.py file.

Adding Your TA2 Agent to Docker

You can add in your code to the TA2.py (and other code files). Please update the Dockerfile-PARTIAL-TA2 to bring in additional files and requirements-TA2.txt with any python requirements your TA2 agent may need. Logfiles written to the /aiq-sail-on/logs directory will be accessable outside the docker environment and can be saved. Your TA2 agent is responsible for retaining its own results when using the portable generator.

Using an External TA2 Agent

You can run a TA2 agent on the portable generator outside the docker environment. The code requires some Python setup, which we describe below based on an Anaconda environment.

  1. Install Anaconda.

  2. Activate the base Anaconda environment.

[user@host ~]$ source ~/anaconda3/bin/activate
  1. Ensure your base environment is up to date:
(base) [user@host ~]$ conda update -n base -c defaults conda
  1. Create a new environment with the basic versions.
(base) [user@host ~]$ conda create --name aiq-env python=3.7 python-dateutil==2.8.1 psutil pytz numpy
  1. Activate the new environment so we can finish installing the remaining packages.
(base) [user@host ~]$ conda activate aiq-env
  1. Install the remaining packages with pip.
(aiq-env) [user@host ~]$ pip install pika==1.1.0 blosc==1.10.4

Running the External TA2 Agent

To run the TA2 externally you will need to use the config file configs/partial/gui-client.config to communicate with the portable generator, and you will need to use the portable-gui.yml docker-compose file that opens a local port 5432 for the RabbitMQ communication connection. In a terminal window, build and start up the portable generator system

docker-compose -f portable-gui.yml build
docker-compose -f portable-gui.yml up

Then in a second terminal, using the aiq-env Anaconda environment we set up, change to the source directory

(aiq-env) [user@host WSU-Portable-Generator]$ cd source

Then start up the TA2 agent.

(aiq-env) [user@host source]$ python TA2.py --config=../configs/partial/gui-client.config --printout --debug --logfile=logs/log.txt

When you are done make sure to bring down the portable generator system in the docker-compose terminal window

docker-compose -f portable-gui.yml down

TA2 GUI Agents

The GUI-Cartpole.py and GUI-Vizdoom.py agents allow humans to test out the mock novelties in their respective domains. To set up the Python environment for these agents, follow the instructions in Using an External TA2 Agent to set up an Anaconda environment. Once you have followed those instructions there is 1 more package required for the GUI agents

(aiq-env) [user@host ~]$ pip install opencv-python

Running the TA2 GUI Agents

First you need to make sure the TA1.config has been updated to tell the system to generate images (see use_image in TA1 Configuration). Then you need to start up the portable generation system in docker-compose that opens a local port (5672) for the GUI agent to connect to the RabbitMQ communication system

docker-compose -f portable-gui.yml build
docker-compose -f portable-gui.yml up

Now in a separate window, using the aiq-env Anaconda environment we built, change to the source directory

(aiq-env) [user@host WSU-Portable-Generator]$ cd source

Then start up the GUI agent, we will use GUI-Vizdoom.py in this example

(aiq-env) [user@host source]$ python GUI-Vizdoom.py --config=../configs/partial/gui-client.config --printout --ignore-secret

Please note that we included --ignore-secret in the command line args, this ensures you are requesting a new experiment each time you run the GUI agent as the previously stored experiment secret may have been wiped from the database the last time you brought the docker-compose system down.

When you are done please don't forget to bring the docker-compose system down, or you may spend more time debugging some errors than you would like the next time to try to start the system.

docker-compose -f portable-gui.yml down
