Can't run bash init_venv.sh

[123artorux]

Hi i am new to these stuff and i get an error when try to run the venv such as below :

init_venv.sh: line 3: realpath: command not found
init_venv.sh: line 20: virtualenv: command not found
init_venv.sh: line 27: venv/bin/activate: No such file or directory
cat: requirements.txt: No such file or directory
[WARNING] Model optimizer requirements were not installed. Please install the OpenVino toolkit to use one.

Activate a virtual environment to start working:
$ . venv/bin/activate

Is there is something i need to change inside venv.sh file?
