How To Fix yappi: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu yappi is provided by python3-yappi package.

python3-yappi is:

Yappi stands for Yet Another Python Profiler. It supports Multithread/CPU time profiling.

CPython standard distribution comes with three profilers. cProfile, Profile and hotshot. cProfile is implemented as a C module based on lsprof, Profile is in pure Python and hotshot can be seen as a small subset of a cProfile.

The major issue is that all of these profilers lack support for multi-threaded programs and CPU time.

If you want to profile a multi-threaded application, you must give an entry point to these profilers and then maybe merge the outputs. None of these profilers are designed to work on long-running multi-threaded application. It is impossible to profile an application retrieve the statistics then stop and then start later on the fly (without affecting the profiled application).

This package contains the Python 3.x module.

To fix this problem, we can install more using the command below.

sudo apt-get -y install python3-yappi

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install python3-yappi.

sudo apt -y install python3-yappi

sudo aptitude install python3-yappi
