i don't get a submit50 commands even i installed pip ,python, wsl, ubuntu

I installed pip ,python, wsl, ubuntu and even so, there is no submit50 command

python version:

 python --version
 Python 3.10.6

pip version:

 pip3 --version
 pip 22.2.2

git version:

git --version
git version 2.35.1.windows.2

wsl & ubuntu:

  wsl -l -v
  NAME      STATE           VERSION
 * Ubuntu    Running         2

and after no such command:

 submit50
 'submit50' is not recognized as an internal or external command,
  operable program or batch file.

What is the problem?
