Cannot import name BlockBlobService from azure.storage.blob

Question

Although, there are many similar questions to the one I am asking, but non of them have helped me.

I am trying to store the file into my azure storage blob through directly through my system using the python script.

Here is the script I am using:

import os, uuid, sys
from azure.storage.blob import BlockBlobService, PublicAccess

def run_sample():
    try:
        block_blob_service = BlockBlobService(account_name=<acc-name>, account_key=<acc-key>)

        # Create a file in Documents to test the upload and download.
        local_path=os.path.abspath(os.path.curdir)
        local_file_name =input("Enter file name to upload : ")
        full_path_to_file =os.path.join(local_path, local_file_name)

        print("Temp file = " + full_path_to_file)
        print("\nUploading to Blob storage as blob" + local_file_name)

        # Upload the created file, use local_file_name for the blob name
        container_name ='handwritten-text'
        block_blob_service.create_blob_from_path(container_name, local_file_name, full_path_to_file)

        # List the blobs in the container
        print("\nList blobs in the container")
        generator = block_blob_service.list_blobs(container_name)
        for blob in generator:
            print("\t Blob name: " + blob.name)
    
    except Exception as e:
        print(e)


# Main method.
if __name__ == '__main__':
    run_sample()

Although, if I am running the script, I am getting the error as:

ImportError: cannot import name 'BlockBlobService' from 'azure.storage.blob' (/home/nishant/anaconda3/envs/mera_env/lib/python3.7/site-packages/azure/storage/blob/__init__.py)

Here is the result of pip freeze:

azure-cognitiveservices-vision-computervision==0.6.0

azure-common==1.1.25

azure-core==1.8.0

azure-storage-blob==12.3.2

How can I resolve the issue?

Answer 1

v12 sdk uses BlobServiceClient instead of BlockBlobService, if you want to use BlockBlobService should use v2 sdk. For v12 sdk usage, please refer to this official doc.

So please change it to from azure.storage.blob import BlobServiceClient, PublicAccess.
