我有一个简单的python脚本，可以按照这里的说明部署为azure函数。
当脚本被触发时（为blob上传的事件网格事件设置），它会遇到一个运行时错误：

Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: Functions.imageeventgridtrigger --->
  Microsoft.Azure.WebJobs.Script.Rpc.RpcException: Result: Failure
  Exception: ModuleNotFoundError: No module named 'numpy' Stack:   File
  "/azure-functions-host/workers/python/3.6/LINUX/X64/azure_functions_worker/dispatcher.py",
  line 242, in _handle__function_load_request
      func_request.metadata.entry_point)   File "/azure-functions-host/workers/python/3.6/LINUX/X64/azure_functions_worker/loader.py",
  line 66, in load_function
      mod = importlib.import_module(fullmodname)   File "/usr/local/lib/python3.6/importlib/__init__.py", line 126, in
  import_module
      return _bootstrap._gcd_import(name[level:], package, level)   File "/home/site/wwwroot/imageeventgridtrigger/__init__.py", line 3, in

      import numpy as np    at Microsoft.Azure.WebJobs.Script.Description.OutOfProcInvoker.InvokeCore(Object[]
  parameters, FunctionInvocationContext context) in
  /src/azure-functions-host/src/WebJobs.Script/Description/OutOfProc/OutOfProcInvoker.cs:line
  82*

[截取其余跟踪]部署是通过vscode集成进行的。根据日志输出，requirements文件似乎部分执行：

requirements文件有其他依赖项，但它们不会出现在日志输出中（直到第3行！）。尝试多次部署，但结果相同。Requirements.txt：

azure-functions
numpy==1.16.4
matplotlib==3.1.0
opencv_python==4.1.1.26
scikit_image==0.15.0
scipy==1.2.1
skimage==0.0

Python脚本：

mport json
import logging
import numpy as np
import matplotlib
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt
import statistics
import cv2
import os
import scipy
import scipy.signal as ss
import skimage
from skimage.filters import (threshold_otsu, threshold_niblack, threshold_sauvola)
from skimage.restoration import denoise_nl_means, estimate_sigma

import azure.functions as func

def main(event: func.EventGridEvent):
    result = json.dumps({
        'id': event.id,
        'data': event.get_json(),
        'topic': event.topic,
        'subject': event.subject,
        'event_type': event.event_type,
    })

    logging.info('Python EventGrid trigger processed an event: %s', result)
    logging.info('cv2 %s ', cv2.__version__)
    logging.info('matplotlib %s ', matplotlib.__version__)
    logging.info('scipy %s ', scipy.__version__)
    logging.info('skimage %s', skimage.__version__)

如果要求中只提到azure-functions，则部署和触发器工作正常。这是针对Always On应用程序服务计划，并且正在Linux上进行部署。部署出现了什么问题？
