In particular, `MyRLAgen In this particular skill, which chiefly serves for demonstration purposes, we implement a very basic RL agent. The agent trains a model of price of `n` goods: it aims to discover the most likely price of each good. To this end, the agent randomly selects one of the `n` goods on each training step and then chooses as an `action` the price which it deems is most likely accepted. Each good is represented by an id and the possible price range `[1,100]` divided into 100 integer bins. For each price bin, a `PriceBandit` is created which models the likelihood of this price. In particular, a price bandit maintains a [beta distribution](https://en.wikipedia.org/wiki/Beta_distribution). The beta distribution is initialized to the uniform distribution. Each time the price associated with a given `PriceBandit` is accepted or rejected the distribution maintained by the `PriceBandit` is updated. For each good, the agent can therefore over time learn which price is most likely. -

If it is a loss, we abort and warn the developer. The helper private function `_build_data_payload`, is where we read data from our sensor or in case we don’t have a sensor generate a random number. - -### Step 5: Create the dialogues - -When we are negotiating with other AEA we would like to keep track on these negotiations for various reasons. -So create a new file and name it dialogues.py. Inside this file add the following code: - -``` python -from typing import Dict, Optional - -from aea.helpers.dialogue.base import Dialogue as BaseDialogue -from aea.helpers.dialogue.base import DialogueLabel as BaseDialogueLabel -from aea.helpers.search.models import Description -from aea.mail.base import Address -from aea.protocols.base import Message -from aea.skills.base import Model - -from packages.fetchai.protocols.fipa.dialogues import FipaDialogue, FipaDialogues - - -class Dialogue(FipaDialogue): - """The dialogue class maintains state of a dialogue and manages it.""" - - def __init__( - self, - dialogue_label: BaseDialogueLabel, - agent_address: Address, - role: BaseDialogue.Role, - ) -> None: - """ - Initialize a dialogue. - - :param dialogue_label: the identifier of the dialogue - :param agent_address: the address of the agent for whom this dialogue is maintained - :param role: the role of the agent this dialogue is maintained for - - :return: None - """ - FipaDialogue.__init__( - self, dialogue_label=dialogue_label, agent_address=agent_address, role=role - ) - self.temp_data = None # type: Optional[Dict[str, str]] - self.proposal = None # type: Optional[Description] - - -class Dialogues(Model, FipaDialogues): - """The dialogues class keeps track of all dialogues.""" - - def __init__(self, **kwargs) -> None: - """ - Initialize dialogues. - - :return: None - """ - Model.__init__(self, **kwargs) - FipaDialogues.__init__(self, self.context.agent_address) - - @staticmethod - def role_from_first_message(message: Message) -> BaseDialogue.Role: - """ - Infer the role of the agent from an incoming or outgoing first message - - :param message: an incoming/outgoing first message - :return: the agent's role - """ - return FipaDialogue.AgentRole.SELLER - - def create_dialogue( - self, dialogue_label: BaseDialogueLabel, role: BaseDialogue.Role, - ) -> Dialogue: - """ - Create an instance of dialogue. - - :param dialogue_label: the identifier of the dialogue - :param role: the role of the agent this dialogue is maintained for - - :return: the created dialogue - """ - dialogue = Dialogue( - dialogue_label=dialogue_label, agent_address=self.agent_address, role=role - ) - return dialogue -``` - -The dialogues class stores dialogue with each `client_aea` in a list so we can have access to previous messages and -enable us to identify possible communications problems between the `my_thermometer` AEA and the `my_client` AEA. It also keeps track of the data that we offer for sale during the proposal phase. - -### Step 6: Create the data_model - -Each AEA in the oef needs a Description in order to be able to register as a service. The data model will help us create this description. Create a new file and call it `thermometer_data_model.py` and paste the following code: - -``` python -from aea.helpers.search.models import Attribute, DataModel - -SCHEME = {"country": "UK", "city": "Cambridge"} - - -class Thermometer_Datamodel(DataModel): - """Data model for the thermo Agent.""" - - def __init__(self): - """Initialise the dataModel.""" - self.attribute_country = Attribute("country", str, True) - self.attribute_city = Attribute("city", str, True) - - super().__init__( - "thermometer_datamodel", [self.attribute_country, self.attribute_city] - ) -``` - -This data model registers to the [OEF search node](../oef-ledger) as an AEA that is in the UK and specifically in Cambridge. If a `client_AEA` searches for AEA in the UK the [OEF search node](../oef-ledger) will respond with the address of our AEA. - -### Step 7: Update the YAML files - -Since we made so many changes to our AEA we have to update the `skill.yaml` to contain our newly created scripts and the details that will be used from the strategy. - -Firstly, we will update the `skill.yaml`. Make sure that your `skill.yaml` matches with the following code - -``` yaml -name: thermometer -author: fetchai -version: 0.2.0 -license: Apache-2.0 -fingerprint: {} -aea_version: '>=0.4.0, <0.5.0' -description: "The thermometer skill implements the functionality to sell data." -behaviours: - service_registration: - class_name: ServiceRegistrationBehaviour - args: - services_interval: 60 -handlers: - fipa: - class_name: FIPAHandler - args: {} -models: - strategy: - class_name: Strategy - args: - price_per_row: 1 - seller_tx_fee: 0 - currency_id: 'FET' - ledger_id: 'fetchai' - has_sensor: True - is_ledger_tx: True - dialogues: - class_name: Dialogues - args: {} -protocols: ['fetchai/fipa:0.3.0', 'fetchai/oef_search:0.2.0', 'fetchai/default:0.2.0'] -ledgers: ['fetchai'] -dependencies: - pyserial: {} - temper-py: {} -``` - -We must pay attention to the models and the strategy’s variables. Here we can change the price we would like to sell each reading for or the currency we would like to transact with. Lastly, the dependencies are the third party packages we need to install in order to get readings from the sensor. - -Finally, we fingerprint our new skill: - -``` bash -aea fingerprint skill thermometer -``` - -This will hash each file and save the hash in the fingerprint. This way, in the future we can easily track if any of the files have changed. - - -## Client_AEA - -### Step 1: Create the AEA - -Create a new AEA by typing the following command in the terminal: - -``` bash -aea create my_client -cd my_client -``` - -Our newly created AEA is inside the current working directory. Let’s create our new skill that will handle the purchase of the thermometer data. Type the following command: - -``` bash -aea scaffold skill thermometer_client -``` - -This command will create the correct structure for a new skill inside our AEA project You can locate the newly created skill inside the skills folder and it must contain the following files: - -- `behaviours.py` -- `handlers.py` -- `my_model.py` -- `skills.yaml` -- `__init__.py` - -### Step 2: Create the behaviour - -A Behaviour class contains the business logic specific to actions initiated by the AEA rather than reactions to other events. - -Open the `behaviours.py` (`my_client/skills/thermometer_client/behaviours.py`) and add the following code: - -``` python -from typing import cast - -from aea.skills.behaviours import TickerBehaviour - -from packages.fetchai.protocols.oef_search.message import OefSearchMessage -from packages.fetchai.skills.thermometer_client.strategy import Strategy - -DEFAULT_SEARCH_INTERVAL = 5.0 - - -class MySearchBehaviour(TickerBehaviour): - """This class implements a search behaviour.""" - - def __init__(self, **kwargs): - """Initialize the search behaviour.""" - search_interval = cast( - float, kwargs.pop("search_interval", DEFAULT_SEARCH_INTERVAL) - ) - super().__init__(tick_interval=search_interval, **kwargs) - - def setup(self) -> None: - """Implement the setup for the behaviour.""" - strategy = cast(Strategy, self.context.strategy) - if self.context.ledger_apis.has_ledger(strategy.ledger_id): - balance = self.context.ledger_apis.token_balance( - strategy.ledger_id, - cast(str, self.context.agent_addresses.get(strategy.ledger_id)), - ) - if balance > 0: - self.context.logger.info( - "[{}]: starting balance on {} ledger={}.".format( - self.context.agent_name, strategy.ledger_id, balance - ) - ) - else: - self.context.logger.warning( - "[{}]: you have no starting balance on {} ledger!".format( - self.context.agent_name, strategy.ledger_id - ) - ) - self.context.is_active = False - - def act(self) -> None: - """ - Implement the act. - - :return: None - """ - strategy = cast(Strategy, self.context.strategy) - if strategy.is_searching: - query = strategy.get_service_query() - search_id = strategy.get_next_search_id() - oef_msg = OefSearchMessage( - performative=OefSearchMessage.Performative.SEARCH_SERVICES, - dialogue_reference=(str(search_id), ""), - query=query, - ) - oef_msg.counterparty = self.context.search_service_address - self.context.outbox.put_message(message=oef_msg) - - def teardown(self) -> None: - """ - Implement the task teardown. - - :return: None - """ - strategy = cast(Strategy, self.context.strategy) - if self.context.ledger_apis.has_ledger(strategy.ledger_id): - balance = self.context.ledger_apis.token_balance( - strategy.ledger_id, - cast(str, self.context.agent_addresses.get(strategy.ledger_id)), - ) - self.context.logger.info( - "[{}]: ending balance on {} ledger={}.".format( - self.context.agent_name, strategy.ledger_id, balance - ) - ) -``` - -This Behaviour will search on the[OEF search node](../oef-ledger) with a specific query at regular tick intervals. - -### Step 3: Create the handler - -So far, we have tasked the AEA with sending search queries to the [OEF search node](../oef-ledger).
