Methods

TranslationServiceClient

TranslationServiceClient(
    transport=None,
    channel=None,
    credentials=None,
    client_config=None,
    client_info=None,
    client_options=None,
)

Constructor.

Parameters
NameDescription
channel grpc.Channel

DEPRECATED. A Channel instance through which to make calls. This argument is mutually exclusive with credentials; providing both will raise an exception.

credentials google.auth.credentials.Credentials

The authorization credentials to attach to requests. These credentials identify this application to the service. If none are specified, the client will attempt to ascertain the credentials from the environment. This argument is mutually exclusive with providing a transport instance to transport; doing so will raise an exception.

client_config dict

DEPRECATED. A dictionary of call options for each method. If not specified, the default configuration is used.

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.

client_options Union[dict, google.api_core.client_options.ClientOptions]

Client options used to set user options on the client. API Endpoint should be set through client_options.

batch_translate_text

batch_translate_text(parent, source_language_code, target_language_codes, input_configs, output_config, models=None, glossaries=None, labels=None, retry=<_MethodDefault._DEFAULT_VALUE: <object object>>, timeout=<_MethodDefault._DEFAULT_VALUE: <object object>>, metadata=None)

Translates a large volume of text in asynchronous batch mode. This function provides real-time output as the inputs are being processed. If caller cancels a request, the partial results (for an input file, it's all or nothing) may still be available on the specified output location.

This call returns immediately and you can use google.longrunning.Operation.name to poll the status of the call.

.. rubric:: Example

from google.cloud import translate_v3beta1

client = translate_v3beta1.TranslationServiceClient()

parent = client.location_path('[PROJECT]', '[LOCATION]')

TODO: Initialize source_language_code:

source_language_code = ''

TODO: Initialize target_language_codes:

target_language_codes = []

TODO: Initialize input_configs:

input_configs = []

TODO: Initialize output_config:

output_config = {}

def callback(operation_future): ... # Handle result. ... result = operation_future.result()

response.add_done_callback(callback)

metadata = response.metadata()

Parameters
NameDescription
parent str

Required. Location to make a call. Must refer to a caller's project. Format: projects/{project-id}/locations/{location-id}. The global location is not supported for batch translation.

output_config Union[dict, OutputConfig]

Required. Output configuration. If 2 input configs match to the same file (that is, same input path), we don't generate output for duplicate inputs. If a dict is provided, it must be of the same form as the protobuf message OutputConfig

models dict[str -> str]

Optional. The models to use for translation. Map's key is target language code. Map's value is model name. Value can be a built-in general model, or an AutoML Translation model. The value format depends on model type: - AutoML Translation models: projects/{project-id}/locations/{location-id}/models/{model-id} - General (built-in) models: projects/{project-id}/locations/{location-id}/models/general/nmt, projects/{project-id}/locations/{location-id}/models/general/base If the map is empty or a specific model is not requested for a language pair, then default google model (nmt) is used.

Optional. Glossaries to be applied for translation. It's keyed by target language code. If a dict is provided, it must be of the same form as the protobuf message TranslateTextGlossaryConfig

Label keys and values can be no longer than 63 characters (Unicode codepoints), can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. Label values are optional. Label keys must start with a letter. See https://cloud.google.com/translate/docs/labels for more information.

TODO: Initialize contents:

contents = []

TODO: Initialize target_language_code:
