I'm getting Azure.Storage.Blob can not import in Azure ML notebook, what is the reason?

import cv2
import time
from matplotlib import pyplot as plt
from azure.storage.blob import BlockBlobService
import os

4th line is giving error, I checked package is installed

error:-

ImportError Traceback (most recent call last)
Cell In[1], line 4
2 import time
3 from matplotlib import pyplot as plt
----> 4 from azure.storage.blob import BlockBlobService

ImportError: cannot import name 'BlockBlobService' from 'azure.storage.blob' (/anaconda/envs/azureml_py38/lib/python3.9/site-packages/azure/storage/blob/__init__.py)

Start with the failing import in the Azure ML notebook and inspect the installed package at /anaconda/envs/azureml_py38/lib/python3.9/site-packages/azure/storage/blob/__init__.py. Check which blob client API that environment exposes and compare it with the code's BlockBlobService import. Done means identifying the cause and documenting or confirming a working import path.
