This tutorial demonstrates how to use CUDA graph kernel annotations for semantic profiling traces with custom visualization lanes. Features: - End-to-end workflow from graph capture to visualization - Transformer block example with annotated regions - Post-processing to merge annotations into profiler traces - Custom stream assignments for semantic organization - Version checking for cuda-bindings compatibility - Clear error messages with upgrade instructions The tutorial includes: - mark_kernels() context manager usage - Graph capture with enable_annotations=True - Profiling and trace post-processing - Before/after comparison - Troubleshooting guide Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>

This is required for the CUDA graph annotations tutorial to work with full annotation support. The cudaGraphNodeGetToolsId API was added in cuda-bindings 13.3.0.
- Removed check_cuda_bindings_version() function since PyTorch core now provides the warning via _probe_tools_id() - Updated PyTorch requirement from 2.0+ to 2.13+ (required for the annotation APIs used in this tutorial) - Simplified error messaging to reference PyTorch's built-in warnings
Changed the overview to emphasize: - Ability to add semantic labels to kernels - Understanding what each kernel does during profiling - Labeling and organizing kernels by function Rather than focusing on splitting kernels across streams, the overview now centers on the annotation feature itself.
Updated the prerequisites card at the top to show PyTorch 2.12+ (was still showing 2.0). Also updated cuda-python to cuda-bindings for consistency.
Added chrome://tracing screenshots showing: - Before: All 65 kernels on single stream with auto-generated names - After: Kernels organized into semantic lanes (streams 61, 62) with meaningful labels (attention, mlp) Screenshots demonstrate the value of kernel annotations for understanding execution structure and identifying components.
Move `if __name__ == "__main__": main()` to immediately after the main() function definition (line ~404) so it executes during the Sphinx Gallery build process. Sphinx Gallery requires the execution guard to be positioned right after the function definition, not at the end of the file, to properly capture and execute the tutorial code during documentation generation.

you should be able to use earlier version?
These files were accidentally included in the previous commit: - traces/ directory (both root and advanced_source/) - Screenshot PNG files - CUDA_GRAPH_TUTORIAL_README.md These are build artifacts and temporary files that should not be committed to the repository.
