NVIDIA Tools Extension (NVTX) Python Binding

NVTX (NVIDIA Tools Extension SDK) is a C-based API with Python wrappers for annotating application code with events, ranges, and resources. These annotations provide contextual information for NVIDIA developer tools like Nsight Systems and Nsight Compute, enabling visual profiling and performance analysis of CPU and GPU activities in Python applications. The `nvidia-nvtx-cu12` package provides bindings specifically for CUDA 12.x environments. It is actively maintained with frequent updates, often tied to CUDA toolkit releases.
