We are trying to use Aspose PDF and Apose word in Azure Databricks by using python. It is crashing when try to set liscence or try to use any function by below message. Is there any one successful

Cause The issue you’re experiencing with Aspose libraries in Azure Databricks, resulting in the Python kernel becoming unresponsive, may be due to several factors, including compatibility issues, resource limitations, or incorrect configurations when setting the license or using the libraries. Solution Here are some steps to troubleshoot and resolve the issue: 1. Check Compatibility: Ensure that the versions of Aspose libraries you are using are compatible with the Python version running in Azure Databricks. Refer to the official Aspose documentation for compatibility details. 2. Resource Allocation: Azure Databricks may have resource limitations. Ensure that your cluster has sufficient memory and CPU resources allocated. Increase the cluster size or use a different instance type if necessary. 3. License Configuration: When setting the license, ensure that the license file is correctly referenced and accessible. Use the following code snippet to set the license: python import aspose.words as aw # Load the license license = aw.License() license.set_license("path/to/your/license.lic") Verify that the path to the license file is correct and that the file is accessible from your Databricks environment. 4. Error Handling: Implement error handling to catch exceptions that may arise when using Aspose functions. This can help identify specific issues causing the kernel to crash. python try: # Your Aspose code here except Exception as e: print(f"An error occurred: {e}") 5. Testing in Isolation: Test the Aspose functionality in a smaller, isolated notebook to determine if the issue persists. This can help identify whether the problem is related to the specific notebook or the overall environment. Next Steps - Review the logs for any specific error messages that might provide more insight into the issue.

  • If the problem continues, reach out to Aspose support with detailed logs and the code you are using for further assistance. Please implement these steps and let me know if you need any further help!

@baludharmarajan Can you share the code snippet where the error occurs? Also, please specify what versions of Aspose.PDF for Python and Aspose.Words for Python you are using? Once we have these details, we will start investigating and try to reproduce the issue.

Hi Anastasia,

We are using the latest version of aspose python releases. Databricks is having python 3.12. We are only trying Aspose in notebook. The driver and executor is both set for 28GB ram (standard Ds4_V2). Databricks runtime is 16.3. Please find the code below:

#%pip install aspose.words spose.pdf aspose.slides
#dbutils.library.restartPython()
