Azure Function App in Python cannot see modules

• To achieve your requirement, create requirements.txt file with all the required python packages in root folder of your project.
• The requirements.txt is a simple text file which is used to specify the Python packages that are required by the Azure Function. When you deploy your Azure Function, the packages listed in the requirements.txt file are installed automatically in the function’s environment.

I have created a simple python Azure function locally:

Project Structure:

requirements.txt:

I have used below packages in my project:

azure-functions
numpy
pandas

Code Snippet:

import datetime
import json
import logging

import azure.functions as func
import numpy as np
import pandas as pd

app = func.FunctionApp()

@app.route(route="http_trigger", auth_level=func.AuthLevel.ANONYMOUS)
def http_trigger(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    arr = np.array([1, 2, 3])
    df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})

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

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully with {arr} and {df}.")
    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
        )

• Create and activate virtual environment, install the required packages:

Running locally:

• Created Python Lunix Azure Function App with App Service Plan Basic tier.

Deployed my function to Azure Function App:

• When you run the function, it activates virtual environment and install the dependencies which are mentioned in requirements.txt.
