Nsight Python
An open-source Python interface released by NVIDIA for profiling GPU kernels directly within Python code, reading hardware counter metrics, evaluating cache and clock control, and measuring kernel fusion effects, thereby integrating performance profiling into Python workflows.
Timeline (last 90 days)
Nsight Python's clock control feature enables developers to lock the GPU clock frequency, thereby eliminating interference from frequency changes in performance measurements.
Kernel-level collection usually introduces additional runtime overhead, and measurement results need to be cross-validated in a non-profiled state.
Nsight Python lacks the interactive source-level correlation view that Nsight Compute provides.
The original material does not mention Nsight Python's support for other acceleration backends (non-CUDA), and the official documentation should be taken as authoritative.
Nsight Python is better suited to being embedded in existing test or tuning scripts for quick screening and regression comparison, and after anomalous kernels are found, graphical tools can be used to dig deeper.
