How to deploy Azure functions, and ensure the packages get updated

I have my functions working locally, then when I deploy them I am getting errors like :

Result: Failure Exception: ModuleNotFoundError: No module named 'azure.cosmosdb'. Troubleshooting Guide: https://aka.ms/functions-modulenotfound Stack: File "/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/dispatcher.py", line 284, in _handle__function_load_request func = loader.load_function( File "/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/utils/wrappers.py", line 42, in call raise extend_exception_message(e, message) File "/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/utils/wrappers.py", line 40, in call return func(*args, **kwargs) File "/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/loader.py", line 76, in load_function mod = importlib.import_module(fullmodname) File "/usr/local/lib/python3.8/importlib/init.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "/home/site/wwwroot/user-add/init.py", line 4, in from azure.cosmosdb.table.tableservice import TableService

I think this looks like the Python env on the Azure side doesn't have azure as I specify on my import like so:

import logging

import azure.functions as func
import azure.cosmosdb.table
from azure.cosmosdb.table.tableservice import TableService
from azure.cosmosdb.table.models import Entity


def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    user_id = req.params.get('user_id')
    if not user_id:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            user_id = req_body.get('user_id')

    if user_id:

        the_connection_string = "redacted"
        table_service = TableService(endpoint_suffix="table.cosmos.azure.com",
                     connection_string=the_connection_string)

        # table_service.create_table('usertable')

        user = {"PartitionKey": "user",
                "RowKey": user_id}

        table_service.insert_entity('usertable', user)

        return func.HttpResponse(f"{user_id} added to the user database")

    else:
        return func.HttpResponse(
            "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
            status_code=200
        )

I don't understand what I need to do to force an equivalent pip install on their side? Which is mad as it is supposed to be serverless?

Please first make sure you have add the azure-cosmos to the requirements.txt file.

When you deploy Python azure function to azure, it will install modules based on this file.
