求助：Azure云端Jupyter Notebook突然停止执行代码问题

Hey David, sorry to hear you're stuck with your Azure-hosted Jupyter Notebook refusing to run code—let's walk through some targeted steps to get to the bottom of this, since you've already checked off the basic fixes:

• Check your Azure Notebook instance status
  Azure often pauses idle notebook instances to conserve resources, or you might be hitting CPU/memory limits. Head to your Azure Notebook's management dashboard to confirm the instance is marked as "Running". If it's paused, start it back up. Also, keep an eye on resource usage metrics—if your instance is consistently maxed out, that could block code from executing.

• Test with a minimal code snippet first
  Create a new notebook cell and run nothing but this super simple line:

  print("Hello World")
  

  If this works, the problem is tied to your specific code (like an infinite loop, blocking I/O operation, or broken dependency). If even this fails, the issue lies with the notebook environment itself.

• Try Chrome's Incognito Mode
  Corrupted browser cache or cookies can mess with the cloud notebook's interactive features. Open a Chrome Incognito window, log back into your Azure account, and access the notebook again. If code runs here, clear your regular Chrome cache/cookies and try once more.

• Validate kernel and environment health

  • Create a new notebook and switch to a different Python kernel (e.g., if you were using Python 3.9, try 3.8) to test execution. This can rule out a corrupted kernel environment.
  • Open a terminal within your Azure Notebook and run pip list to check for dependency errors. If you suspect a broken library, reinstall it with pip install --force-reinstall [library-name].

• Dig into notebook logs
  Most Azure Notebook instances offer access to kernel logs. Look for a "Logs" or "Kernel Status" option in the interface—these logs will often show specific errors (like kernel startup failures, timeouts, or permission issues) that aren't visible in the main notebook view.

• Start fresh with a new instance
  If all else fails, create a new Azure Notebook instance, copy your code over in small chunks (to avoid bringing over problematic code), and test execution. Sometimes the original instance's configuration files get corrupted, and starting over resolves the issue.

Hope one of these steps gets your notebook running smoothly again!
