Azure Personalizer client library for Python
Azure Personalizer
is a cloud-based service that helps your applications choose the best content item to show your users. You can use the Personalizer service to determine what product to suggest to shoppers or to figure out the optimal position for an advertisement. After the content is shown to the user, your application monitors the user's reaction and reports a reward score back to the Personalizer service. This ensures continuous improvement of the machine learning model, and Personalizer's ability to select the best content item based on the contextual information it receives.
Getting started
Prerequisites

Python 3.7 or later is required to use this package.
You must have an Azure subscription and a
Personalizer resource to use this package.

Install the package
Install the Azure Personalizer client library for Python with pip:
pip install azure-ai-personalizer

Note: This version of the client library defaults to the 2022-09-01-preview version of the service.

Key concepts
PersonalizerClient
The synchronous PersonalizerClient and
asynchronous PersonalizerClient provide synchronous and asynchronous operations to:

Manage the machine learning model and learning settings for the Personalizer service.
Manage the properties of the Personalizer service such as the learning mode, exploration percentage.
Run counterfactual evaluations on prior historical event data.
Rank a set of actions, then activate and reward the event.
Use multi-slot personalization when there are more than one slots.
Manage the properties of the Personalizer service.
Run counterfactual evaluations on prior historical event data.

Examples
The following examples outline the main scenarios when using personalizer in single-slot and multi-slot configurations.

Send rank and reward when using a single slot
Send rank and reward when using multiple slots

Send rank and reward
from azure.ai.personalizer import PersonalizerClient
from azure.core.credentials import AzureKeyCredential

endpoint = "https://<my-personalizer-instance>.cognitiveservices.azure.com/"
credential = AzureKeyCredential("<api_key>")

client = PersonalizerClient(endpoint, credential)

# The list of actions to be ranked with metadata associated for each action.
actions = [

{"mostWatchedByAge": "50-55"},
],
},

"id": "Video2",
"features": [
{"videoType": "movie", "videoLength": 120, "director": "StevenSpielberg"},
{"mostWatchedByAge": "40-45"},
],
},
]

# Context of the user to which the action must be presented.
context_features = [
{"currentContext": {"day": "tuesday", "time": "night", "weather": "rainy"}},
{
"userContext": {
"payingUser": True,

request = {

}

rank_response = client.rank(request)
print("Sending reward event")
client.reward(rank_response.get("eventId"), {"value": 1.0})

Send multi-slot rank and reward

# We want to rank the actions for two slots.

rank_response = client.rank_multi_slot(request)
print("Sending reward event for Main Article slot")
client.reward_multi_slot(
rank_response.get("eventId"),
{"reward": [{"slotId": "Main Article", "value": 1.0}]})

Troubleshooting
General
Personalizer client library will raise exceptions defined in Azure Core.
Logging
This library uses the standard logging library for logging.
Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO level.
Detailed DEBUG level logging, including request/response bodies and unredacted
headers, can be enabled on the client or per-operation with the logging_enable keyword argument.
See full SDK logging documentation with examples here.
Optional Configuration
Optional keyword arguments can be passed in at the client and per-operation level.
The azure-core reference documentation
describes available configurations for retries, logging, transport protocols, and more.
