If you’re using Linux, you can try perf, a powerful performance profiling tool now supported in Python 3.12. To learn more about perf, check out the Python 3.12 Preview: Support For the Linux perf Profiler tutorial. Finally, py-spy and Scalene are third-party libraries that you can consid...
Like getenv(s), but returns NULL if -E was passed on the command line (i.e. if Py_IgnoreEnvironmentFlag is set). Py_UNUSED(arg) Use this for unused arguments in a function definition to silence compiler warnings. Example: int func(int a, int Py_UNUSED(b)) { return a; }. 3.4 ...

Working on a machine learning project means we need to experiment. Having a way to configure your script easily will help you move faster. In Python, we have a way to adapt the code from a command line. In this tutorial, we are going to see how we can leverage the command line argume...
For more information, check out the async profiling documentation and the Profiler.async_mode property. Pyinstrument has a documentation site, including full Python API docs! v3.4.2 Fix a bug that caused --show, --show-regex, --show-all to be ignored on the command line. v3.4.1 Under-...
How it works: the main process will not start a server, but spawn a new child process using the same command line arguments used to start the main process. All module-level code is executed at least twice! Be careful. The child process will have os.environ['BOTTLE_CHILD'] set to True...
This method of the Stats class accumulates additional profiling information into the current profiling object. Its arguments should refer to filenames created by the corresponding version of profile.run() or cProfile.run(). Statistics for identically named (re: file, line, name) functions are aut...
