Azure Core Library for Python

1.39.0 verified Tue May 12 auth: no python install: stale quickstart: stale

The Azure Core Library for Python provides essential functionalities for Azure SDK clients, including authentication, logging, and HTTP transport. Current version: 1.39.0. Release cadence: Regular updates with new features and fixes.

pip install azure-core

Common errors

error ModuleNotFoundError: No module named 'azure.core' ↓

cause The 'azure-core' package is not installed in the Python environment.

fix

Install the package using 'pip install azure-core'.

error ImportError: You need to install 'azure-core' to use this feature ↓

cause The 'azure-core' package is missing, which is required by the Azure SDK.

fix

Ensure 'azure-core' is installed by running 'pip install azure-core'.

error ImportError: cannot import name 'VirtualMachinesOperations' from partially initialized module 'azure.mgmt.compute.v2022_03_01.operations' ↓

cause A circular import issue occurs when directly importing operation classes from the Azure SDK.

fix

Use the client interface provided by the SDK instead of importing operation classes directly.

error ImportError: DLL load failed while importing _rust: The specified procedure could not be found. ↓

cause A version compatibility issue exists between the 'azure-identity' package and the Python environment.

fix

Update the 'azure-identity' package to the latest version using 'pip install --upgrade azure-identity'.

error ImportError: cannot import name 'AccessTokenInfo' from 'azure.core.credentials' ↓

cause The `AccessTokenInfo` class was introduced in a newer version (e.g., 1.33.0) of `azure-core`, and your installed version is older, or there's a dependency conflict where an older version is being used.

fix

Upgrade the azure-core library to the latest version, or a version that includes AccessTokenInfo: pip install --upgrade azure-core azure-identity (if using azure-identity which often relies on it).

Warnings

breaking The 'azure' meta-package is deprecated as of version 5.0.0 and can no longer be installed. Install individual packages as needed. ↓

fix Install specific Azure SDK packages like 'azure-core' directly.

fix Install specific Azure SDK packages like 'azure-core' directly.

gotcha Attempting to 'await' an asynchronous operation (e.g., from an Azure SDK transport client) outside of an 'async def' function will result in a 'SyntaxError: 'await' outside function'. This typically happens when using async client methods without defining the caller function as asynchronous. ↓

fix Ensure that any function containing 'await' expressions is declared with 'async def'. For top-level script execution, wrap the async call in an async function and use `asyncio.run()`.

breaking Using 'await' outside of an 'async def' function context will raise a SyntaxError. Top-level 'await' is not directly supported in standard Python scripts prior to Python 3.11 for modules, or Python 3.7 for REPL. ↓

fix Ensure all 'await' expressions are placed inside a function defined with 'async def'. If using 'await' at the top level, ensure your Python version and execution environment supports it (e.g., Python 3.11+ module, IPython/Jupyter, or a custom event loop runner).

Basic usage of HttpRequest from azure-core

from azure.core.pipeline import HttpRequest

# Create an HttpRequest object
request = HttpRequest('GET', 'https://example.com')

# Send the request (assuming a transport is set up)
response = await transport.send(request)

print(response.status_code)
