FILE: sample_build_model.py

DESCRIPTION:
    This sample demonstrates how to build a model. For this sample, you can use the training
    documents found in https://aka.ms/azsdk/formrecognizer/sampletrainingfiles

    More details on setting up a container and required file structure can be found here:
    https://aka.ms/azsdk/formrecognizer/buildtrainingset

USAGE:
    python sample_build_model.py

    Set the environment variables with your own values before running the sample:
    1) AZURE_FORM_RECOGNIZER_ENDPOINT - the endpoint to your Form Recognizer resource.
    2) AZURE_FORM_RECOGNIZER_KEY - your Form Recognizer API key
    3) CONTAINER_SAS_URL - The shared access signature (SAS) Url of your Azure Blob Storage container with your training files.
