+1 for py-spy. I would love to try out Scalene but the application I have does something funky with pickling for multiprocessing, breaking Scalene in the process (my fault, not Scalene's, I'll be looking into that). Py-spy worked, including catching all the sub-processes. Feeding the py-spy JSON output into https://speedscope.app https://speedscope.app makes for a very easy way to profile in a time crunch if you don't have time to get familiar with CLI tools or can't install stuff locally but have a browser and internet connection.
