Memray is a memory profiler for Python
https://github.com/bloomberg/memray
Notable features:
- Traces every function call so it can accurately represent the call stack, unlike sampling profilers.
- Also handles native calls in C/C++ libraries so the entire call stack is present in the results.
- Blazing fast! Profiling causes minimal slowdown in the application. Tracking native code is somewhat slower, but this can be enabled or disabled on demand.
- It can generate various reports about the collected memory usage data, like flame graphs.
- Works with Python threads.
- Works with native-threads (e.g. C++ threads in native extensions)
Memray can help with the following problems:
- Analyze allocations in applications to help discover the cause of high memory usage.
- Find memory leaks.
- Find hotspots in code which cause a lot of allocations.
