如何查询Azure Notebook的Python SDK版本及解决Blob导入错误

Hey there! Let's work through your Azure Storage Blob SDK issues step by step.

How to Check Your Azure Storage SDK Version #

To confirm exactly which versions of the Azure Storage libraries are running in your Azure Notebook environment, run these commands directly in a notebook cell:

• Check the legacy azure-storage package version:

  !pip show azure-storage
  

  Or verify within Python:

  import azure.storage
  print(azure.storage.__version__)
  

• Check the modern azure-storage-blob package version:

  !pip show azure-storage-blob
  

  Or verify within Python:

  import azure.storage.blob
  print(azure.storage.blob.__version__)
  

Your hunch about version differences is totally right: the BlobServiceClient class belongs to Azure Storage Blob SDK v12+, while older versions (like v0.36.0 of azure-storage) rely on BlockBlobService instead.

Fixing the ImportError: cannot import name 'BlobServiceClient' #

The core problem here is a namespace conflict between the legacy azure-storage package (v0.36.0) and the modern azure-storage-blob package (v12.3.0) you installed. These two packages overlap in their module structure, causing import confusion. Here's how to resolve it:

1. Uninstall conflicting packages to clean up your environment:

   !pip uninstall -y azure-storage azure-storage-blob
   

2. Reinstall only the modern, standalone SDK:

   !pip install azure-storage-blob --upgrade
   

3. Verify the installation to confirm you're on v12+:

   import azure.storage.blob
   print(azure.storage.blob.__version__)
   

4. Use the correct import statement for v12+ SDK:

   from azure.storage.blob import BlobServiceClient
   

Why didn't upgrading azureml-sdk help? The azureml-sdk often includes a dependency on the legacy azure-storage package, which would reintroduce the conflict. By explicitly uninstalling and reinstalling the standalone azure-storage-blob package, you ensure you're using the modern library structure.

If you need to work with the legacy SDK for compatibility reasons, use this import instead:

from azure.storage.blob import BlockBlobService
