[Usage]: How to write scoring script when deploying to a managed Azure machine learning real-time endpoint? #13491

Description

@dprokhorov17

I'd like to deploy my custom model on managed Azure machine learning real-time endpoint. So, I've registered my model, but it's not clear to me how to write a proper scoring script in azure when the model is intended to receive OpenAI API compatible calls. The docs in azure provide this basic sample:

import os
import logging
import json
import numpy
import joblib


def init():
    """
    This function is called when the container is initialized/started, typically after create/update of the deployment.
    You can write the logic here to perform init operations like caching the model in memory
    """
    global model
    # AZUREML_MODEL_DIR is an environment variable created during deployment.
    # It is the path to the model folder (./azureml-models/$MODEL_NAME/$VERSION)
    # Please provide your model's folder name if there is one
    model_path = os.path.join(
        os.getenv("AZUREML_MODEL_DIR"), "model/sklearn_regression_model.pkl"
    )
    # deserialize the model file back into a sklearn model
    model = joblib.load(model_path)
    logging.info("Init complete")


def run(raw_data):
    """
    This function is called for every invocation of the endpoint to perform the actual scoring/prediction.
    In the example we extract the data from the json input and call the scikit-learn model's predict()
    method and return the result back
    """
    logging.info("model 1: request received")
    data = json.loads(raw_data)["data"]
    data = numpy.array(data)
    result = model.predict(data)
    logging.info("Request processed")
    return result.tolist()

Has anyone done similar thing?

How would you like to use vllm

I want to run inference of molmo7B (https://huggingface.co/allenai/Molmo-7B-D-0924) on managed Azure real-time endpoint. I don't know how to integrate it with vllm.
