Methods

ReasoningEngine

ReasoningEngine(reasoning_engine_name: str)

Retrieves a Reasoning Engine resource.

Parameter
Name	Description
reasoning_engine_name	str Required. A fully-qualified resource name or ID such as "projects/123/locations/us-central1/reasoningEngines/456" or "456" when project and location are initialized or passed.

create

create(
    reasoning_engine: vertexai.reasoning_engines._reasoning_engines.Queryable,
    *,
    requirements: typing.Optional[typing.Union[str, typing.Sequence[str]]] = None,
    reasoning_engine_name: typing.Optional[str] = None,
    display_name: typing.Optional[str] = None,
    description: typing.Optional[str] = None,
    gcs_dir_name: str = "reasoning_engine",
    sys_version: typing.Optional[str] = None,
    extra_packages: typing.Optional[typing.Sequence[str]] = None
) -> vertexai.reasoning_engines._reasoning_engines.ReasoningEngine

Creates a new ReasoningEngine.

The Reasoning Engine will be an instance of the reasoning_engine that was passed in, running remotely on Vertex AI.

Sample src_dir contents (e.g. ./user_src_dir):

user_src_dir/
|-- main.py
|-- requirements.txt
|-- user_code/
|   |-- utils.py
|   |-- ...
|-- ...

To build a Reasoning Engine:

remote_app = ReasoningEngine.create(
    local_app,
    requirements=[
        # I.e. the PyPI dependencies listed in requirements.txt
        "google-cloud-aiplatform==1.25.0",
        "langchain==0.0.242",
        ...
    ],
    extra_packages=[
        "./user_src_dir/main.py", # a single file
        "./user_src_dir/user_code", # a directory
        ...
    ],
)

Parameters
Name	Description
reasoning_engine	ReasoningEngineInterface Required. The Reasoning Engine to be created.
requirements	Union[str, Sequence[str]] Optional. The set of PyPI dependencies needed. It can either be the path to a single file (requirements.txt), or an ordered list of strings corresponding to each line of the requirements file.
reasoning_engine_name	str Optional. A fully-qualified resource name or ID such as "projects/123/locations/us-central1/reasoningEngines/456" or "456" when project and location are initialized or passed. If specifying the ID, it should be 4-63 characters. Valid characters are lowercase letters, numbers and hyphens ("-"), and it should start with a number or a lower-case letter. If not provided, Vertex AI will generate a value for this ID.
display_name	str Optional. The user-defined name of the Reasoning Engine. The name can be up to 128 characters long and can comprise any UTF-8 character.
description	str Optional. The description of the Reasoning Engine.
gcs_dir_name	CreateReasoningEngineOptions Optional. The GCS bucket directory under staging_bucket to use for staging the artifacts needed.
sys_version	str Optional. The Python system version used. Currently supports any of "3.8", "3.9", "3.10", "3.11". If not specified, it defaults to the "{major}.{minor}" attributes of sys.version_info.
extra_packages	Sequence[str] Optional. The set of extra user-provided packages (if any).

Exceptions
Type	Description
ValueError	If sys.version is not supported by ReasoningEngine.
ValueError	If the project was not set using vertexai.init.
ValueError	If the location was not set using vertexai.init.
ValueError	If the staging_bucket was not set using vertexai.init.
ValueError	If the staging_bucket does not start with "gs://".
FileNotFoundError	If extra_packages includes a file or directory
tha	does not exist.:

Returns
Type	Description
ReasoningEngine	The Reasoning Engine that was created.

delete

delete(sync: bool = True) -> None

Deletes this Vertex AI resource. WARNING: This deletion is permanent.

Parameter
Name	Description
sync	bool Whether to execute this deletion synchronously. If False, this method will be executed in concurrent Future and any downstream object will be immediately returned and synced when the Future has completed.

list

list(
    filter: typing.Optional[str] = None,
    order_by: typing.Optional[str] = None,
    project: typing.Optional[str] = None,
    location: typing.Optional[str] = None,
    credentials: typing.Optional[google.auth.credentials.Credentials] = None,
    parent: typing.Optional[str] = None,
) -> typing.List[google.cloud.aiplatform.base.VertexAiResourceNoun]

List all instances of this Vertex AI Resource.

Example Usage:

aiplatform.BatchPredictionJobs.list( filter='state="JOB_STATE_SUCCEEDED" AND display_name="my_job"', )

aiplatform.Model.list(order_by="create_time desc, display_name")

Parameters
Name	Description
filter	str Optional. An expression for filtering the results of the request. For field names both snake_case and camelCase are supported.
order_by	str Optional. A comma-separated list of fields to order by, sorted in ascending order. Use "desc" after a field name for descending. Supported fields: display_name, create_time, update_time
project	str Optional. Project to retrieve list from. If not set, project set in aiplatform.init will be used.

credentials	auth_credentials.Credentials Optional. Custom credentials to use to retrieve list. Overrides credentials set in aiplatform.init.
parent	str Optional. The parent resource name if any to retrieve list from.

operation_schemas

operation_schemas() -> typing.Sequence[typing.Dict[str, typing.Any]]

Returns the (Open)API schemas for the Reasoning Engine.

query

query(**kwargs) -> typing.Dict[str, typing.Any]

Runs the Reasoning Engine to serve the user query.

This will be based on the .query(...) method of the python object that was passed in when creating the Reasoning Engine.

Returns
Type	Description
dict[str, Any]	The response from serving the user query.

to_dict

to_dict() -> typing.Dict[str, typing.Any]

Returns the resource proto as a dictionary.

wait

wait()

Helper method that blocks until all futures are complete.
