Need Python SDK to call Form Recognizer Service for document classification

Question

Hi ,

I am doing one POC where i need to classify scanned documents. To achieve this I am using Azure form recognizer Custom Classification Model. In Studio i am able to train the model and able to test it but how we can do it using python. Do you have python SDK for this.

I googled i found some code but it's not working and giving me some error . How we can solve it ? Any tip or suggestion.

Python Code :

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

endpoint = [My Azure Service End point ]
key = [Key]
classifier_id = [classifier_id]
path_to_sample_documents = [My Local File Path]
document_analysis_client = DocumentAnalysisClient(
    endpoint=endpoint, credential=AzureKeyCredential(key)
)
with open(path_to_sample_documents, "rb") as f:
    poller = document_analysis_client.begin_classify_document(
        classifier_id, document=f
    )
result = poller.result()

print("----Classified documents----")

Error :

    poller = document_analysis_client.begin_classify_document(
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'DocumentAnalysisClient' object has no attribute 'begin_classify_document'. Did you mean: 'begin_analyze_document'?

Thanks

Answer 1

@Abhijeet Pratap Singh begin_classify_document() method will be available in the pre-release version of the SDK 3.3.0.b1since this is equivalent to custom classification model of FR, please check if you have installed this version and try again.

If you have just started using the python SDK, then please try the GA version 3.2.0 and there are several examples on the GitHub repo to analyze documents with the prebuilt or custom models.

For SDK reference, please use this link and select the required SDK version to lookup the reference.

I hope this helps!!
