scalene

Why we included this project

Scalene is a Python profiler that reports CPU, GPU, and memory usage line by line, with low overhead, so it stays usable on real code. Its distinguishing trick is that it can hand the profile to an LLM and return concrete optimization suggestions, which gives you next steps instead of a wall of numbers. The GPU and memory tracking is what makes it stand out for people profiling ML training loops or data pipelines, since those bottlenecks are the hardest to see with ordinary tools. It runs from the command line, as a VS Code extension, or through a web interface.
