azure-storage-python: cannot import name 'BlockBlobService'

Hi @melzoghbi, I’m unable to reproduce this problem. It does not seem to be a problem with the storage package. Could you please try again with a different virtual environment? Thanks!

I think there is some dependency bug in the source code (version azure-storage-blob==2.1.0 ) of blockblobservice.py and init.py under site-packages/azure/storage/blob/ directory. Because when I type in from azure.storage.blob.blockblobservice import BlockBlobService it worked.

Ok. I’ve been able to figure out how to get BlobServiceClient and BlockBlobService running in Azure Notebooks (thanks in part to @harmonyliu!):

• !pip uninstall azure -y
• !pip install azure==4.0.0
• from azure.storage.blob.blockblobservice import BlockBlobService
• from azure.storage.blob import BlobServiceClient Hope this helps

@melzoghbi which version of Python are you using?

For me it worked after I installed azure package: pip install azure

I noticed that it uninstalls latest version (12.0) of azure-storage-blob

Hi @courtenayparserr probably you are using the most recent package？ If the package version is 12.0.0 then try to create a new virtual environment and do: pip install azure-storage-blob==2.1.0 You will be able to import BlockBlobService

Works perfectly fine for me:

virtualenv venv
source venv/bin/activate
pip install azure-storage-blob==0.37.1
python

from azure.storage.blob import BlockBlobService

pip freeze output

I’d suggest updating to a newer version and increasing the logging verbosity for diagnosis. As @zezha-msft said, it sounds like something with your overall system setup isn’t correct…

Hi @harmonyliu to use BlockBlobService in azure-storage-blob==2.1.0 make sure you have a clean virtual environment(It’s highly recommended to create a new one) and just do pip install azure-storage-blob==2.1.0 No extra command is needed.

Let me know if it’s still not working

That didn’t work for me. Still getting this issue.

How do we move past this?

For me it was just

pip install azure-storage-blob==2.1.0

Hi @dxkaufman Thanks for reaching out. There’s no BlockBlobService in version>=12.0.0. Please see the wiki https://github.com/Azure/azure-storage-python/wiki#frequently-encountered-problem-no-module-named-azurestorageblob

To get text content of blob in v12.3.2, you should do the following thing

        bsc = BlobServiceClient(
            self.account_url(storage_account, "blob"),
            credential=account_key)

        blob_client = bsc.get_blob_client(your_container_name, your_blob_name)

        blob_client.upload_blob(text_data)

        # Act
        stream = blob_client.download_blob(max_concurrency=2, encoding='UTF-8')
        content = stream.readall()  # this will give you the text content

@SeaDude I think that solution doesn’t work anymore, I’ve tried quite a few times with every possible solution.

I need to know if anyone is able to run BlobServiceClient and BlockBlobService together.

this worked for me when I was dealing with BlockBlobService import issues

This works for me

pip install azure-storage --upgrade pip install azure-storage-blob --upgrade pip install azure --upgrade

after this pip freeze gives

azure==4.0.0 azure-storage==0.36.0 azure-storage-blob==1.5.0

now I am able to run following from azure.storage.blob import BlockBlobService, PublicAccess

Your code might still be using the legacy Python BlobSDK (https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-python-legacy) But you might have update the library to the latest version. Use this SDK now to update your code https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-python

This works for me

pip install azure-storage --upgrade pip install azure-storage-blob --upgrade pip install azure --upgrade

after this pip freeze gives

azure==4.0.0 azure-storage==0.36.0 azure-storage-blob==1.5.0

now I am able to run following from azure.storage.blob import BlockBlobService, PublicAccess

you are a legend, worked for me. thanks!

@xiafu-msft,

Thank you for the example of how to use BlobServiceClient to get a BlobClient. I now see this option listed in the SDK docs here.

An alternative is to instantiate a separate BlobClient using a SAS. Not sure if its any easier, but the way I did it was:

blob_client = BlobClient.from_blob_url(blob_url = sas_token)

with open("./sampleFile.txt", "rb") as data:
    blob_client.upload_blob(data)

Hi @xiafu-msft Thanks for the quick response. I was starting to get that idea, although I was looking at SDK documentation that seemed to indicate it was still part of the model. I think the docs aren’t super clear about what version they relate to.

I appreciate the sample. All the samples I was looking at last night seem to create a container before accessing it, even when the description is just for reading a blob. I found that a little confusing, though I surmised that the assumption was that the container didn’t exist yet, and your example seems to make that clearer.

@vipulgupta2048 I just left the old version (v2.1) altogether and implemented everything on (v12.0) 😃
