Step-by-Step Instructions to Resolve SystemError

1. Identify the Failing Line:
   
• Review the notebook to locate the line in the configuration cell that is causing the SystemError.
• If the line has been commented out, uncomment it to identify the exact issue.
  
  
2. Check for Syntax or Logic Errors:
   
• Ensure that there are no syntax errors in the notebook code.
• Verify the logic of the code to ensure it aligns with the intended operations.
  
  
3. Run the Notebook Again:
   
• Execute the notebook to see if the SystemError persists.
• If a different error appears, proceed to the next section.

Troubleshooting Memory Allocation Issues

1. Identify the Memory Allocation Error:
   
• If the error message indicates that the output exceeds the resources allocated to the Notebooks Compute Instance, note the memory allocation details.
  
  
2. Increase Memory Allocation:
   
• Access the Configuration Manager:
• Navigate to Admin > System Configuration / System Management > Configuration.
• Select the 5-click config menu > Warehouse-Service > notebooks.compute.defaultMemoryInMibs.
• Increase the memory allocation from the default value (e.g., 256 MiB) to a higher value (e.g., 1024 MiB).
  
  
3. Verify the Changes:
   
• After increasing the memory allocation, run the notebook again to ensure the error is resolved.

Additional Tips

• Testing with Real Data:
  
• When testing notebooks with real data, ensure that the sample size is manageable within the allocated resources.
• For larger datasets, consider increasing the memory allocation proportionally.
  
  
• Feedback and Support:
  
• If the issue persists, contact support with detailed information about the error and the context of its occurrence.
• Providing feedback on your experience can help improve the support process.
