Methods

ImageAnnotatorClient

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

Constructor.

Parameters

Name	Description
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.

annotate_image

annotate_image(request, retry=None, timeout=None)

Run image detection and annotation for an image.

.. rubric:: Example

from google.cloud.vision_v1 import ImageAnnotatorClient client = ImageAnnotatorClient() request = { ... 'image': { ... 'source': {'image_uri': 'https://foo.com/image.jpg'}, ... }, ... } response = client.annotate_image(request)

Parameters

Name	Description
retry	Optional[google.api_core.retry.Retry] A retry object used to retry requests. If None is specified, requests will not be retried.
timeout	Optional[float] The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.

async_batch_annotate_files

async_batch_annotate_files(requests, retry=<object object>, timeout=<object object>, metadata=None)

Run asynchronous image detection and annotation for a list of generic files, such as PDF files, which may contain multiple pages and multiple images per page. Progress and results can be retrieved through the google.longrunning.Operations interface. Operation.metadata contains OperationMetadata (metadata). Operation.response contains AsyncBatchAnnotateFilesResponse (results).

.. rubric:: Example

from google.cloud import vision_v1

client = vision_v1.ImageAnnotatorClient()

TODO: Initialize requests:

requests = []

response = client.async_batch_annotate_files(requests)

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

response.add_done_callback(callback)

Handle metadata.

metadata = response.metadata()

Parameters

Name	Description
requests	list[Union[dict, AsyncAnnotateFileRequest]] Individual async file annotation requests for this batch. If a dict is provided, it must be of the same form as the protobuf message AsyncAnnotateFileRequest
retry	Optional[google.api_core.retry.Retry] A retry object used to retry requests. If None is specified, requests will not be retried.
timeout	Optional[float] The amount of time, in seconds, to wait for the request to complete. Note that if retry is specified, the timeout applies to each individual attempt.
metadata	Optional[Sequence[Tuple[str, str]]] Additional metadata that is provided to the method.

Exceptions

Type	Description
google.api_core.exceptions.GoogleAPICallError	If the request failed for any reason.
google.api_core.exceptions.RetryError	If the request failed due to a retryable error and retry attempts failed.
ValueError	If the parameters are invalid.

async_batch_annotate_images

async_batch_annotate_images(requests, output_config, retry=<object object>, timeout=<object object>, metadata=None)

Run asynchronous image detection and annotation for a list of images.

Progress and results can be retrieved through the google.longrunning.Operations interface. Operation.metadata contains OperationMetadata (metadata). Operation.response contains AsyncBatchAnnotateImagesResponse (results).

This service will write image annotation outputs to json files in customer GCS bucket, each json file containing BatchAnnotateImagesResponse proto.
