Make sure you're using the latest stable pip version of azure-ai-formrecognizer which is version 3.2.1 as per this Link1. And DocumentAnalysisClient was introduced in pip version 3.2.0b1 as mentioned in this Link2. So make sure your azure-ai-formrecognizer version is 3.2.0b1 or above.

I installed the latest version of azure-ai-formrecognizer and did not receive any import error with DocumentAnalysisClient, Refer below:-

pip install azure-ai-formrecognizer==3.2.0 OR 
pip install azure-ai-formrecognizer 

Code:-

I have referred the below code from this MS Document and followed the same document.

Copied my API Key and endpoint from here:-

I have set the key and endpoint as Environment variable in my terminal like below:-

setx FR_KEY <Key>
setx FR_ENDPOINT <endpoint>

Close the Terminal and VS Code and open again for above variables to populate. Now, Run the code below:-

While running the code below which I referred from this MS Document, I did not receive any Import error:-

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

# use your `key` and `endpoint` environment variables key = os.environ.get('FR_KEY') endpoint = os.environ.get('FR_ENDPOINT')

# formatting function def format_polygon(polygon):
    if not polygon:
        return "N/A"
    return ", ".join(["[{}, {}]".format(p.x, p.y) for p in polygon])


def analyze_read():
    # sample form document
    formUrl = "https://raw.githubusercontent.com/Azure-Samples/cognitive-services-REST-api-samples/master/curl/form-recognizer/rest-api/read.png"

    document_analysis_client = DocumentAnalysisClient(
        endpoint=endpoint, credential=AzureKeyCredential(key)
    )

    poller = document_analysis_client.begin_analyze_document_from_url(
        "prebuilt-read", formUrl
    )
    result = poller.result()

    print("Document contains content: ", result.content)

    for idx, style in enumerate(result.styles):
        print(
            "Document contains {} content".format(
                "handwritten" if style.is_handwritten else "no handwritten"
            )
        )

    for page in result.pages:
        print("----Analyzing Read from page #{}----".format(page.page_number))
        print(
            "Page has width: {} and height: {}, measured with unit: {}".format(
                page.width, page.height, page.unit
            )
        )

        for line_idx, line in enumerate(page.lines):
            print(
                "...Line # {} has text content '{}' within bounding box '{}'".format(
                    line_idx,
                    line.content,
                    format_polygon(line.polygon),
                )
            )

        for word in page.words:
            print(
                "...Word '{}' has a confidence of {}".format(
                    word.content, word.confidence
                )
            )

    print("----------------------------------------")


if __name__ == "__main__":
    analyze_read()
