class azure.ai.formrecognizer.aio.DocumentAnalysisClient(endpoint: str, credential: Union[AzureKeyCredential, AsyncTokenCredential], **kwargs: Any)

DocumentAnalysisClient analyzes information from documents and images. It is the interface to use for analyzing with prebuilt models (receipts, business cards, invoices, identity documents), analyzing layout from documents, analyzing general document types, and analyzing custom documents with built models. It provides different methods based on inputs from a URL and inputs from a stream.

Note

DocumentAnalysisClient should be used with API versions 2021-09-30-preview and up. To use API versions <=v2.1, instantiate a FormRecognizerClient.

Parameters

• endpoint (str) – Supported Cognitive Services endpoints (protocol and hostname, for example: https://westus2.api.cognitive.microsoft.com).

• credential (AzureKeyCredential or TokenCredential) – Credentials needed for the client to connect to Azure. This is an instance of AzureKeyCredential if using an API key or a token credential from azure.identity.

Keyword Arguments

api_version (str or DocumentAnalysisApiVersion) – The API version of the service to use for requests. It defaults to the latest service version. Setting to an older version may result in reduced feature compatibility. To use API versions <=v2.1, instantiate a FormRecognizerClient.

New in version 2021-09-30-preview: The DocumentAnalysisClient and its client methods.

Example:

Creating the DocumentAnalysisClient with an endpoint and API key.

from azure.core.credentials import AzureKeyCredential
from azure.ai.formrecognizer.aio import DocumentAnalysisClient

endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
key = os.environ["AZURE_FORM_RECOGNIZER_KEY"]

document_analysis_client = DocumentAnalysisClient(endpoint, AzureKeyCredential(key))

Creating the DocumentAnalysisClient with a token credential.

"""DefaultAzureCredential will use the values from these environment
variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET
"""
from azure.ai.formrecognizer.aio import DocumentAnalysisClient
from azure.identity.aio import DefaultAzureCredential

endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
credential = DefaultAzureCredential()

document_analysis_client = DocumentAnalysisClient(endpoint, credential)

async begin_analyze_document(model: str, document: Union[bytes, IO[bytes]], **kwargs: Any) → azure.core.polling._async_poller.AsyncLROPoller[azure.ai.formrecognizer._models.AnalyzeResult]

Analyze field text and semantic values from a given document.

Parameters

• model (str) – A unique model identifier can be passed in as a string. Use this to specify the custom model ID or prebuilt model ID. Prebuilt model IDs supported can be found here: https://aka.ms/azsdk/formrecognizer/models

• document (bytes or IO[bytes]) – JPEG, PNG, PDF, TIFF, or BMP type file stream or bytes.

Keyword Arguments

• pages (str) – Custom page numbers for multi-page documents(PDF/TIFF). Input the page numbers and/or ranges of pages you want to get in the result. For a range of pages, use a hyphen, like pages=”1-3, 5-6”. Separate each page number or range with a comma.

• locale (str) – Locale hint of the input document. See supported locales here: https://aka.ms/azsdk/formrecognizer/supportedlocales.

• continuation_token (str) – A continuation token to restart a poller from a saved state.

Returns

class azure.ai.formrecognizer.aio.DocumentModelAdministrationClient(endpoint: str, credential: Union[AzureKeyCredential, AsyncTokenCredential], **kwargs: Any)

DocumentModelAdministrationClient is the Form Recognizer interface to use for building and managing models.

It provides methods for building models, as well as methods for viewing and deleting models, viewing document model operations, accessing account information, copying models to another Form Recognizer resource, and composing a new model from a collection of existing models.

Note

DocumentModelAdministrationClient should be used with API versions 2021-09-30-preview and up. To use API versions <=v2.1, instantiate a FormTrainingClient.

Parameters

• endpoint (str) – Supported Cognitive Services endpoints (protocol and hostname, for example: https://westus2.api.cognitive.microsoft.com).

• credential (AzureKeyCredential or TokenCredential) – Credentials needed for the client to connect to Azure. This is an instance of AzureKeyCredential if using an API key or a token credential from azure.identity.

Keyword Arguments

api_version (str or DocumentAnalysisApiVersion) – The API version of the service to use for requests. It defaults to the latest service version. Setting to an older version may result in reduced feature compatibility. To use API versions <=v2.1, instantiate a FormTrainingClient.

New in version 2021-09-30-preview: The DocumentModelAdministrationClient and its client methods.

Example:

Creating the DocumentModelAdministrationClient with an endpoint and API key.

from azure.core.credentials import AzureKeyCredential
from azure.ai.formrecognizer.aio import DocumentModelAdministrationClient

endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
key = os.environ["AZURE_FORM_RECOGNIZER_KEY"]

async begin_build_model(source: str, **kwargs: Any) → azure.ai.formrecognizer.aio._async_polling.AsyncDocumentModelAdministrationLROPoller[azure.ai.formrecognizer._models.DocumentModel]

Build a custom model.

The request must include a source parameter that is an externally accessible Azure storage blob container URI (preferably a Shared Access Signature URI). Models are built using documents that are of the following content type - ‘application/pdf’, ‘image/jpeg’, ‘image/png’, ‘image/tiff’, or ‘image/bmp’. Other types of content in the container is ignored.

Parameters

source (str) – An Azure Storage blob container’s SAS URI. A container URI (without SAS) can be used if the container is public. For more information on setting up a training data set, see: https://aka.ms/azsdk/formrecognizer/buildtrainingset

Keyword Arguments

• model_id (str) – A unique ID for your model. If not specified, a model ID will be created for you.

• description (str) – An optional description to add to the model.

• prefix (str) – A case-sensitive prefix string to filter documents in the source path. For example, when using an Azure storage blob URI, use the prefix to restrict sub folders. prefix should end in ‘/’ to avoid cases where filenames share the same prefix.

• continuation_token (str) – A continuation token to restart a poller from a saved state.

Returns

An instance of an AsyncDocumentModelAdministrationLROPoller. Call result() on the poller object to return a DocumentModel.

Return type

FormRecognizerClient extracts information from forms and images into structured data. It is the interface to use for analyzing with prebuilt models (receipts, business cards, invoices, identity documents), recognizing content/layout from forms, and analyzing custom forms from trained models. It provides different methods based on inputs from a URL and inputs from a stream.

Note

FormRecognizerClient should be used with API versions <=v2.1. To use API versions 2021-09-30-preview and up, instantiate a DocumentAnalysisClient.

Parameters

• endpoint (str) – Supported Cognitive Services endpoints (protocol and hostname, for example: https://westus2.api.cognitive.microsoft.com).

• credential (AzureKeyCredential or AsyncTokenCredential) – Credentials needed for the client to connect to Azure. This is an instance of AzureKeyCredential if using an API key or a token credential from azure.identity.

Keyword Arguments

api_version (str or FormRecognizerApiVersion) – The API version of the service to use for requests. It defaults to API version v2.1.

See fields found on a business card here: https://aka.ms/formrecognizer/businesscardfields

Parameters

business_card (bytes or IO[bytes]) – JPEG, PNG, PDF, TIFF, or BMP type file stream or bytes.

Keyword Arguments

• locale (str) – Locale of the business card. Supported locales include: en-US, en-AU, en-CA, en-GB, and en-IN.

• include_field_elements (bool) – Whether or not to include all lines per page and field elements such as lines, words, and selection marks for each form field.

• content_type (str or FormContentType) – Content-type of the body sent to the API. Content-type is auto-detected, but can be overridden by passing this keyword argument. For options, see FormContentType.

• pages (list[str]) – Custom page numbers for multi-page documents(PDF/TIFF). Input the page numbers and/or ranges of pages you want to get in the result. For a range of pages, use a hyphen, like pages=[“1-3”, “5-6”]. Separate each page number or range with a comma.

• continuation_token (str) – A continuation token to restart a poller from a saved state.

Returns

An instance of an AsyncLROPoller. Call result() on the poller object to return a list[RecognizedForm].

class azure.ai.formrecognizer.aio.FormTrainingClient(endpoint: str, credential: Union[AzureKeyCredential, AsyncTokenCredential], **kwargs: Any)

FormTrainingClient is the Form Recognizer interface to use for creating and managing custom models. It provides methods for training models on the forms you provide, as well as methods for viewing and deleting models, accessing account properties, copying models to another Form Recognizer resource, and composing models from a collection of existing models trained with labels.

Note

FormTrainingClient should be used with API versions <=v2.1. To use API versions 2021-09-30-preview and up, instantiate a DocumentModelAdministrationClient.

Parameters

• endpoint (str) – Supported Cognitive Services endpoints (protocol and hostname, for example: https://westus2.api.cognitive.microsoft.com).

• credential (AzureKeyCredential or AsyncTokenCredential) – Credentials needed for the client to connect to Azure. This is an instance of AzureKeyCredential if using an API key or a token credential from azure.identity.

Keyword Arguments

api_version (str or FormRecognizerApiVersion) – The API version of the service to use for requests. It defaults to API version v2.1. Setting to an older version may result in reduced feature compatibility. To use the latest supported API version and features, instantiate a DocumentModelAdministrationClient instead.

Example:

Creating the FormTrainingClient with an endpoint and API key.

from azure.core.credentials import AzureKeyCredential
from azure.ai.formrecognizer.aio import FormTrainingClient
endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
key = os.environ["AZURE_FORM_RECOGNIZER_KEY"]

form_training_client = FormTrainingClient(endpoint, AzureKeyCredential(key))

Creating the FormTrainingClient with a token credential.

"""DefaultAzureCredential will use the values from these environment
variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET
"""
from azure.ai.formrecognizer.aio import FormTrainingClient
from azure.identity.aio import DefaultAzureCredential

endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
credential = DefaultAzureCredential()

form_training_client = FormTrainingClient(endpoint, credential)

async begin_copy_model(model_id: str, target: dict, **kwargs: Any) → azure.core.polling._async_poller.AsyncLROPoller[azure.ai.formrecognizer._models.CustomFormModelInfo]

Copy a custom model stored in this resource (the source) to the user specified target Form Recognizer resource. This should be called with the source Form Recognizer resource (with the model that is intended to be copied). The target parameter should be supplied from the target resource’s output from calling the get_copy_authorization() method.

Parameters

• model_id (str) – Model identifier of the model to copy to target resource.

• target (dict) – The copy authorization generated from the target resource’s call to get_copy_authorization().

Keyword Arguments

continuation_token (str) – A continuation token to restart a poller from a saved state.

Returns

An instance of an AsyncLROPoller. Call result() on the poller object to return a CustomFormModelInfo.

Return type

AsyncLROPoller[CustomFormModelInfo]

Raises

HttpResponseError –

async begin_create_composed_model(model_ids: List[str], **kwargs: Any) → azure.core.polling._async_poller.AsyncLROPoller[azure.ai.formrecognizer._models.CustomFormModel]

Creates a composed model from a collection of existing models that were trained with labels.

A composed model allows multiple models to be called with a single model ID. When a document is submitted to be analyzed with a composed model ID, a classification step is first performed to route it to the correct custom model.

Parameters

model_ids (list[str]) – List of model IDs to use in the composed model.

Keyword Arguments

• model_name (str) – An optional, user-defined name to associate with your model.

• continuation_token (str) – A continuation token to restart a poller from a saved state.

async begin_training(training_files_url: str, use_training_labels: bool, **kwargs: Any) → azure.core.polling._async_poller.AsyncLROPoller[azure.ai.formrecognizer._models.CustomFormModel]

Create and train a custom model. The request must include a training_files_url parameter that is an externally accessible Azure storage blob container URI (preferably a Shared Access Signature URI). Note that a container URI (without SAS) is accepted only when the container is public. Models are trained using documents that are of the following content type - ‘application/pdf’, ‘image/jpeg’, ‘image/png’, ‘image/tiff’, or ‘image/bmp’. Other types of content in the container is ignored.

Parameters

• training_files_url (str) – An Azure Storage blob container’s SAS URI. A container URI (without SAS) can be used if the container is public. For more information on setting up a training data set, see: https://docs.microsoft.com/azure/cognitive-services/form-recognizer/build-training-data-set

• use_training_labels (bool) – Whether to train with labels or not. Corresponding labeled files must exist in the blob container if set to True.

Keyword Arguments

• prefix (str) – A case-sensitive prefix string to filter documents in the source path for training. For example, when using an Azure storage blob URI, use the prefix to restrict sub folders for training.

• include_subfolders (bool) – A flag to indicate if subfolders within the set of prefix folders will also need to be included when searching for content to be preprocessed. Not supported if training with labels.

• model_name (str) – An optional, user-defined name to associate with your model.

• continuation_token (str) – A continuation token to restart a poller from a saved state.

Returns

An instance of an AsyncLROPoller. Call result() on the poller object to return a CustomFormModel.

AsyncLROPoller[CustomFormModel]

Raises

HttpResponseError – Note that if the training fails, the exception is raised, but a model with an “invalid” status is still created. You can delete this model by calling delete_model()

New in version v2.1: The model_name keyword argument

Example:

Training a model (without labels) with your custom forms.

from azure.ai.formrecognizer.aio import FormTrainingClient
from azure.core.credentials import AzureKeyCredential

endpoint = os.environ["AZURE_FORM_RECOGNIZER_ENDPOINT"]
key = os.environ["AZURE_FORM_RECOGNIZER_KEY"]
container_sas_url = os.environ["CONTAINER_SAS_URL_V2"]

async with FormTrainingClient(
    endpoint, AzureKeyCredential(key)
) as form_training_client:

    poller = await form_training_client.begin_training(container_sas_url, use_training_labels=False)
    model = await poller.result()

    # Custom model information
    print("Model ID: {}".format(model.model_id))
    print("Status: {}".format(model.status))
    print("Model name: {}".format(model.model_name))
    print("Training started on: {}".format(model.training_started_on))
    print("Training completed on: {}".format(model.training_completed_on))

    print("Recognized fields:")
    # Looping through the submodels, which contains the fields they were trained on
    for submodel in model.submodels:
        print("...The submodel has form type '{}'".format(submodel.form_type))
        for name, field in submodel.fields.items():
            print("...The model found field '{}' to have label '{}'".format(
                name, field.label
            ))

async close() → None

Close the FormTrainingClient session.

async delete_model(model_id: str, **kwargs: Any) → None

Mark model for deletion. Model artifacts will be permanently removed within a predetermined period.

Parameters

model_id (str) – Model identifier.

Return type

None

Raises

HttpResponseError or ResourceNotFoundError –

Example:

Delete a custom model.

await form_training_client.delete_model(model_id=custom_model.model_id)

try:
    await form_training_client.get_custom_model(model_id=custom_model.model_id)
except ResourceNotFoundError:
    print("Successfully deleted model with id {}".format(custom_model.model_id))

async get_account_properties(**kwargs: Any) → azure.ai.formrecognizer._models.AccountProperties

Get information about the models on the form recognizer account.

Returns

Summary of models on account - custom model count, custom model limit.

Return type

AccountProperties

Raises

HttpResponseError –

Example:

Get properties for the form recognizer account.

async with FormTrainingClient(
    endpoint=endpoint, credential=AzureKeyCredential(key)
) as form_training_client:
    # First, we see how many custom models we have, and what our limit is
    account_properties = await form_training_client.get_account_properties()
    print("Our account has {} custom models, and we can have at most {} custom models\n".format(
        account_properties.custom_model_count, account_properties.custom_model_limit
    ))

async get_copy_authorization(resource_id: str, resource_region: str, **kwargs: Any) → Dict[str, Union[str, int]]

Generate authorization for copying a custom model into the target Form Recognizer resource. This should be called by the target resource (where the model will be copied to) and the output can be passed as the target parameter into begin_copy_model().

Parameters

• resource_id (str) – Azure Resource Id of the target Form Recognizer resource where the model will be copied to.

• resource_region (str) – Location of the target Form Recognizer resource. A valid Azure region name supported by Cognitive Services. For example, ‘westus’, ‘eastus’ etc. See https://azure.microsoft.com/global-infrastructure/services/?products=cognitive-services for the regional availability of Cognitive Services.

Returns

A dictionary with values for the copy authorization - “modelId”, “accessToken”, “resourceId”, “resourceRegion”, and “expirationDateTimeTicks”.

Return type

Dict[str, Union[str, int]]

Raises

HttpResponseError –

Example:

Authorize the target resource to receive the copied model

target_client = FormTrainingClient(endpoint=target_endpoint, credential=AzureKeyCredential(target_key))

async with target_client:
    target = await target_client.get_copy_authorization(
        resource_region=target_region,
        resource_id=target_resource_id
    )
# model ID that target client will use to access the model once copy is complete
print("Model ID: {}".format(target["modelId"]))

async get_custom_model(model_id: str, **kwargs: Any) → azure.ai.formrecognizer._models.CustomFormModel

Get a description of a custom model, including the types of forms it can recognize, and the fields it will extract for each form type.

Parameters

model_id (str) – Model identifier.

Returns

CustomFormModel

Return type

CustomFormModel

Raises

HttpResponseError or ResourceNotFoundError –

Example:

Get a custom model with a model ID.

custom_model = await form_training_client.get_custom_model(model_id=model.model_id)
print("\nModel ID: {}".format(custom_model.model_id))
print("Status: {}".format(custom_model.status))
print("Model name: {}".format(custom_model.model_name))
print("Is this a composed model?: {}".format(custom_model.properties.is_composed_model))
print("Training started on: {}".format(custom_model.training_started_on))
print("Training completed on: {}".format(custom_model.training_completed_on))

get_form_recognizer_client(**kwargs: Any) → azure.ai.formrecognizer.aio._form_recognizer_client_async.FormRecognizerClient
