3 min readJan 6, 2025
VizTracer is a powerful tool that can trace and visualize Python code with extremely low performance overhead, helping developers gain a deeper understanding of the program execution process, quickly locate and solve problems in the code. At the same time, it is also very beneficial for analyzing and understanding source code.
Core functions
- • Timeline visualization: Display the calling process of each function in the form of a timeline, including function entry and exit times as well as source code.
- • Multi threading support: Track the execution process of multi-threaded programs without modifying the code, and visually display the interaction relationships between threads.
- • Multi process support: Supports multiprocessing, multiprocessing, os. work(), concurrent. futures, Loky, and other multi process scenarios.
- • Asynchronous support: Support asyncio asynchronous programming and provide options to enhance the tracking effect of asynchronous code.
- • Flame diagram generation: Can generate flame maps to help…
