2. CUPTI Python API Reference

2.1. Documentation Issues

The CUPTI Python API Reference section of the document is automatically generated and has some issues:

• All the CUPTI Python enumerations, functions and classes are listed together in a single section.

• The members of the inner struct/union classes (_py_anon_pod*) are not adequately documented. To get more information for a member, please refer the CUPTI C documentation.

• The kind member of python classes has type int, instead of cupti.cupti.ActivityKind. While using the kind member, please use cupti.cupti.ActivityKind to get the enum value.

• Some parts of the API documentation still cite C enums/data structures instead of mapping them to their Python counterparts.
