Unable to run Aspose.Cells for Python via Java examples


I have downloaded the API package from https://downloads.aspose.com/cells/python/new-releases/aspose.cells-for-python-via-java-20.2/ and unable to run the examples in example.py file. I have also installed the API using pip install aspose-cells. The following exception is thrown when running the example:

The above exception was the direct cause of the following exception:

Thanks for the details.

It looks like JPype version issue. The more recent or very older versions might have issues when working with Aspose.Cells for Python API. We recommend you to use JPype1 version 0.7.0:

Such issues will be fixed in our future releases. As pip command line will install the latest version of jpype, so you have to uninstall the latest version/other version and install the 0.7.0 version specifically.

Let us know if you still find any issue.


It worked. thanks
