PredictionService¶

class google.cloud.aiplatform_v1beta1.services.prediction_service.PredictionServiceAsyncClient(*, credentials: ~typing.Optional[~google.auth.credentials.Credentials] = None, transport: ~typing.Optional[~typing.Union[str, ~google.cloud.aiplatform_v1beta1.services.prediction_service.transports.base.PredictionServiceTransport, ~typing.Callable[[...], ~google.cloud.aiplatform_v1beta1.services.prediction_service.transports.base.PredictionServiceTransport]]] = 'grpc_asyncio', client_options: ~typing.Optional[~google.api_core.client_options.ClientOptions] = None, client_info: ~google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)[source]¶

A service for online predictions and explanations.

Instantiates the prediction service async client.

Parameters:

credentials (Optional[google.auth.credentials.Credentials]) – The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
transport (Optional[Union[str,PredictionServiceTransport,Callable[..., PredictionServiceTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport to use. If a Callable is given, it will be called with the same set of initialization arguments as used in the PredictionServiceTransport constructor. If set to None, a transport is chosen automatically.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “always” (always use the default mTLS endpoint), “never” (always use the default regular endpoint) and “auto” (auto-switch to the default mTLS endpoint if client certificate is present; this is the default value).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is “false” or not set, no client certificate will be used.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
client_info (google.api_core.gapic_v1.client_info.ClientInfo) – The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you’re developing your own client library.

Raises:

google.auth.exceptions.MutualTlsChannelError – If mutual TLS transport creation failed for any reason.

property api_endpoint¶

Return the API endpoint used by the client instance.

Returns:: The API endpoint used by the client instance.
Return type:: str

static cached_content_path(project: str, location: str, cached_content: str) → str¶: Returns a fully-qualified cached_content string.

async cancel_operation(request: Optional[CancelOperationRequest] = None, *, retry: Optional[Union[AsyncRetry, _MethodDefault]] = _MethodDefault._DEFAULT_VALUE, timeout: Union[float, object] = _MethodDefault._DEFAULT_VALUE, metadata: Sequence[Tuple[str, str]] = ()) → None[source]¶

Starts asynchronous cancellation on a long-running operation.

The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn’t support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Parameters:

request (CancelOperationRequest) – The request object. Request message for CancelOperation method.
retry (google.api_core.retry_async.AsyncRetry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

None

Exposes an OpenAI-compatible endpoint for chat completions.

# This snippet has been automatically generated and should be regarded as a
# code template only.
# It will require modifications to work:
# - It may require correct/in-range values for request initialization.
# - It may require specifying regional endpoints when creating the service
#   client as shown in:
#   https://googleapis.dev/python/google-api-core/latest/client_options.html
from google.cloud import aiplatform_v1beta1

async def sample_chat_completions():
    # Create a client
    client = aiplatform_v1beta1.PredictionServiceAsyncClient()

    # Initialize request argument(s)
    request = aiplatform_v1beta1.ChatCompletionsRequest(
        endpoint="endpoint_value",
    )

    # Make the request
    stream = await client.chat_completions(request=request)

    # Handle the response
    async for response in stream:
        print(response)

Parameters:

request (Optional[Union[google.cloud.aiplatform_v1beta1.types.ChatCompletionsRequest, dict]]) – The request object. Request message for [PredictionService.ChatCompletions]
endpoint (str) –
Required. The name of the endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the endpoint field on the request instance; if request is provided, this should not be set.
http_body (google.api.httpbody_pb2.HttpBody) –
Optional. The prediction input. Supports HTTP headers and arbitrary data payload.

This corresponds to the http_body field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry_async.AsyncRetry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Message that represents an arbitrary HTTP body. It should only be used for

payload formats that can’t be represented as JSON, such as raw binary or an HTML page.

This message can be used both in streaming and non-streaming API methods in the request as well as the response.

It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.

Example:

message GetResourceRequest {
// A unique request id. string request_id = 1;

// The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2;

}

service ResourceService {

rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);

rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);

}

Example with streaming methods:

service CaldavService {

rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

}

Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

Return type:

AsyncIterable[google.api.httpbody_pb2.HttpBody]

    )

    # Make the request
    response = await client.raw_predict(request=request)

    # Handle the response
    print(response)

Parameters:

request (Optional[Union[google.cloud.aiplatform_v1beta1.types.RawPredictRequest, dict]]) – The request object. Request message for [PredictionService.RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict].
endpoint (str) –
Required. The name of the Endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the endpoint field on the request instance; if request is provided, this should not be set.
http_body (google.api.httpbody_pb2.HttpBody) –
The prediction input. Supports HTTP headers and arbitrary data payload.

A [DeployedModel][google.cloud.aiplatform.v1beta1.DeployedModel] may have an upper limit on the number of instances it supports per request. When this limit it is exceeded for an AutoML model, the [RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict] method returns an error. When this limit is exceeded for a custom-trained model, the behavior varies depending on the model.

You can specify the schema for each instance in the [predict_schemata.instance_schema_uri][google.cloud.aiplatform.v1beta1.PredictSchemata.instance_schema_uri] field when you create a [Model][google.cloud.aiplatform.v1beta1.Model]. This schema applies when you deploy the Model as a DeployedModel to an [Endpoint][google.cloud.aiplatform.v1beta1.Endpoint] and use the RawPredict method.

This corresponds to the http_body field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry_async.AsyncRetry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Message that represents an arbitrary HTTP body. It should only be used for

payload formats that can’t be represented as JSON, such as raw binary or an HTML page.

This message can be used both in streaming and non-streaming API methods in the request as well as the response.

It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.

Example:

message GetResourceRequest {
// A unique request id. string request_id = 1;

// The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2;

}

service ResourceService {

rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);

rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);

}

Example with streaming methods:

service CaldavService {

rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

}

Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

Return type:

google.api.httpbody_pb2.HttpBody

Returns:

Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource.

A service for online predictions and explanations.

Instantiates the prediction service client.

Parameters:

credentials (Optional[google.auth.credentials.Credentials]) – The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
transport (Optional[Union[str,PredictionServiceTransport,Callable[..., PredictionServiceTransport]]]) – The transport to use, or a Callable that constructs and returns a new transport. If a Callable is given, it will be called with the same set of initialization arguments as used in the PredictionServiceTransport constructor. If set to None, a transport is chosen automatically.
client_options (Optional[Union[google.api_core.client_options.ClientOptions, dict]]) –
Custom options for the client.

1. The api_endpoint property can be used to override the default endpoint provided by the client when transport is not explicitly provided. Only if this property is not set and transport was not explicitly provided, the endpoint is determined by the GOOGLE_API_USE_MTLS_ENDPOINT environment variable, which have one of the following values: “always” (always use the default mTLS endpoint), “never” (always use the default regular endpoint) and “auto” (auto-switch to the default mTLS endpoint if client certificate is present; this is the default value).

2. If the GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is “true”, then the client_cert_source property can be used to provide a client certificate for mTLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is “false” or not set, no client certificate will be used.

3. The universe_domain property can be used to override the default “googleapis.com” universe. Note that the api_endpoint property still takes precedence; and universe_domain is currently not supported for mTLS.
client_info (google.api_core.gapic_v1.client_info.ClientInfo) – The client info used to send a user-agent string along with API requests. If None, then default info will be used. Generally, you only need to set this if you’re developing your own client library.

Raises:

google.auth.exceptions.MutualTLSChannelError – If mutual TLS transport creation failed for any reason.

__exit__(type, value, traceback)[source]¶: Releases underlying transport’s resources.

Warning

ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

property api_endpoint¶

Return the API endpoint used by the client instance.

Returns:: The API endpoint used by the client instance.
Return type:: str

static cached_content_path(project: str, location: str, cached_content: str) → str[source]¶: Returns a fully-qualified cached_content string.

retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

    )

    # Make the request
    stream = client.chat_completions(request=request)

    # Handle the response
    for response in stream:
        print(response)

Parameters:

request (Union[google.cloud.aiplatform_v1beta1.types.ChatCompletionsRequest, dict]) – The request object. Request message for [PredictionService.ChatCompletions]
endpoint (str) –
Required. The name of the endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the endpoint field on the request instance; if request is provided, this should not be set.
http_body (google.api.httpbody_pb2.HttpBody) –
Optional. The prediction input. Supports HTTP headers and arbitrary data payload.

This corresponds to the http_body field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Message that represents an arbitrary HTTP body. It should only be used for

payload formats that can’t be represented as JSON, such as raw binary or an HTML page.

This message can be used both in streaming and non-streaming API methods in the request as well as the response.

It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.

Example:

message GetResourceRequest {
// A unique request id. string request_id = 1;

// The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2;

}

service ResourceService {

rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);

rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);

}

Example with streaming methods:

service CaldavService {

rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

}

Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

Return type:

Iterable[google.api.httpbody_pb2.HttpBody]

Gets the IAM access control policy for a function.

Returns an empty policy if the function exists and does not have a policy set.

Parameters:

request (GetIamPolicyRequest) – The request object. Request message for GetIamPolicy method.
retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.

Returns:

Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources. A Policy is a collection of bindings. A binding binds one or more members to a single role. Members can be user accounts, service accounts, Google groups, and domains (such as G Suite). A role is a named list of permissions (defined by IAM or configured by users). A binding can optionally specify a condition, which is a logic expression that further constrains the role binding based on attributes about the request and/or target resource.

        endpoint="endpoint_value",
    )

    # Make the request
    response = client.raw_predict(request=request)

    # Handle the response
    print(response)

Parameters:

request (Union[google.cloud.aiplatform_v1beta1.types.RawPredictRequest, dict]) – The request object. Request message for [PredictionService.RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict].
endpoint (str) –
Required. The name of the Endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the endpoint field on the request instance; if request is provided, this should not be set.
http_body (google.api.httpbody_pb2.HttpBody) –
The prediction input. Supports HTTP headers and arbitrary data payload.

A [DeployedModel][google.cloud.aiplatform.v1beta1.DeployedModel] may have an upper limit on the number of instances it supports per request. When this limit it is exceeded for an AutoML model, the [RawPredict][google.cloud.aiplatform.v1beta1.PredictionService.RawPredict] method returns an error. When this limit is exceeded for a custom-trained model, the behavior varies depending on the model.

You can specify the schema for each instance in the [predict_schemata.instance_schema_uri][google.cloud.aiplatform.v1beta1.PredictSchemata.instance_schema_uri] field when you create a [Model][google.cloud.aiplatform.v1beta1.Model]. This schema applies when you deploy the Model as a DeployedModel to an [Endpoint][google.cloud.aiplatform.v1beta1.Endpoint] and use the RawPredict method.

This corresponds to the http_body field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Message that represents an arbitrary HTTP body. It should only be used for

payload formats that can’t be represented as JSON, such as raw binary or an HTML page.

This message can be used both in streaming and non-streaming API methods in the request as well as the response.

It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.

Example:

message GetResourceRequest {
// A unique request id. string request_id = 1;

// The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2;

}

service ResourceService {

rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);

rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);

}

Example with streaming methods:

service CaldavService {

rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

}

Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

Return type:

google.api.httpbody_pb2.HttpBody

Parameters:

request (Union[google.cloud.aiplatform_v1beta1.types.GenerateContentRequest, dict]) – The request object. Request message for [PredictionService.GenerateContent].
model (str) –
Required. The fully qualified name of the publisher model or tuned model endpoint to use.

Publisher model format: projects/{project}/locations/{location}/publishers/*/models/*

Tuned model endpoint format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the model field on the request instance; if request is provided, this should not be set.
contents (MutableSequence[google.cloud.aiplatform_v1beta1.types.Content]) –
Required. The content of the current conversation with the model. For single-turn queries, this is a single instance. For multi-turn queries, this is a repeated field that contains conversation history + latest request.

This corresponds to the contents field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Response message for [PredictionService.GenerateContent].

Return type:

Iterable[google.cloud.aiplatform_v1beta1.types.GenerateContentResponse]

    # Make the request
    stream = client.stream_raw_predict(request=request)

    # Handle the response
    for response in stream:
        print(response)

Parameters:

request (Union[google.cloud.aiplatform_v1beta1.types.StreamRawPredictRequest, dict]) – The request object. Request message for [PredictionService.StreamRawPredict][google.cloud.aiplatform.v1beta1.PredictionService.StreamRawPredict].
endpoint (str) –
Required. The name of the Endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

This corresponds to the endpoint field on the request instance; if request is provided, this should not be set.
http_body (google.api.httpbody_pb2.HttpBody) –
The prediction input. Supports HTTP headers and arbitrary data payload.

This corresponds to the http_body field on the request instance; if request is provided, this should not be set.
retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.
timeout (float) – The timeout for this request.
metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

Returns:

Message that represents an arbitrary HTTP body. It should only be used for

payload formats that can’t be represented as JSON, such as raw binary or an HTML page.

This message can be used both in streaming and non-streaming API methods in the request as well as the response.

It can be used as a top-level request field, which is convenient if one wants to extract parameters from either the URL or HTTP template into the request fields and also want access to the raw HTTP body.

Example:

message GetResourceRequest {
// A unique request id. string request_id = 1;

// The raw HTTP body is bound to this field. google.api.HttpBody http_body = 2;

}

service ResourceService {

rpc GetResource(GetResourceRequest)
returns (google.api.HttpBody);

rpc UpdateResource(google.api.HttpBody)
returns (google.protobuf.Empty);

}

Example with streaming methods:

service CaldavService {

rpc GetCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

rpc UpdateCalendar(stream google.api.HttpBody)
returns (stream google.api.HttpBody);

}

Use of this type only changes how the request and response bodies are handled, all other features will continue to work unchanged.

Return type:

Iterable[google.api.httpbody_pb2.HttpBody]
