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

[Sanjay-pujari]

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)
