Python SDK

In this document are exposed all classes implemented inside the Python SDK.

Client

To interact with the Radicalbit AI platform via the SDK, the first thing that must be done is to create the client. The only required parameter is the base_url, which is the URL of the running platform.

from radicalbit_platform_sdk.client import Client

base_url = "http://localhost:9000/"
client = Client(base_url)

Once you have a client instance, you can interact with models inside the platform. ß The available methods of a client instance are:

create_model(model: CreateModel): it is used to create a brand new model inside the platform.

It requires a CreateModel instance and returns the created Model.

from radicalbit_platform_sdk.models import (
	CreateModel,
	DataType,
	FieldType,
	ModelType,
	ColumnDefinition,
	OutputType,
	Granularity,
	SupportedTypes,
)

model_definition = CreateModel(
	name="My model",
	modelType=ModelType.BINARY,
	dataType=DataType.TABULAR,
	granularity=Granularity.HOUR,
	features=[
		ColumnDefinition(
			name="first_name",
			type=SupportedTypes.string,
			field_type=FieldType.categorical
		),
		ColumnDefinition(
			name="last_name",
			type=SupportedTypes.string,
			field_type=FieldType.categorical
		),
		ColumnDefinition(
			name="age",
			type=SupportedTypes.int,
			field_type=FieldType.numerical
		),
	],
	outputs=OutputType(
		prediction=ColumnDefinition(
			name="prediction",
			type=SupportedTypes.float,
			field_type=FieldType.numerical
		),
		output=[
			ColumnDefinition(
				name="adult",
				type=SupportedTypes.string,
				field_type=FieldType.categorical
			)
		],
	),
	target=ColumnDefinition(
		name="prediction",
		type=SupportedTypes.float,
		field_type=FieldType.numerical
	),
	timestamp=ColumnDefinition(
		name="prediction_timestamp",
		type=SupportedTypes.datetime,
		field_type=FieldType.datetime
	),
)

model = client.create_model(model_definition)
