Instantiates the prediction service client.
Name | Description |
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 |
Union[str, PredictionServiceTransport]
The transport to use. If set to None, a transport is chosen automatically. |
client_options |
google.api_core.client_options.ClientOptions
Custom options for the client. It won't take effect if a |
client_info |
google.api_core.gapic_v1.client_info.ClientInfo

Type | Description |
google.auth.exceptions.MutualTLSChannelError | If mutual TLS transport creation failed for any reason. |
__exit__
__exit__(type, value, traceback)
Releases underlying transport's resources.
batch_predict
batch_predict(request: Optional[Union[google.cloud.automl_v1beta1.types.prediction_service.BatchPredictRequest, dict]] = None, *, name: Optional[str] = None, input_config: Optional[google.cloud.automl_v1beta1.types.io.BatchPredictInputConfig] = None, output_config: Optional[google.cloud.automl_v1beta1.types.io.BatchPredictOutputConfig] = None, params: Optional[Mapping[str, str]] = None, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())
Perform a batch prediction. Unlike the online
xref_Predict,
batch prediction result won't be immediately available in the
response. Instead, a long running operation object is returned.
User can poll the operation result via
GetOperation][google.longrunning.Operations.GetOperation]
method. Once the operation is done,
xref_BatchPredictResult
is returned in the
response][google.longrunning.Operation.response]
field.
Available for following ML problems:
- Image Classification
- Image Object Detection
- Video Classification
- Video Object Tracking * Text Extraction
- Tables
