I have tried many things, so how can I solve it?

Because you have python3-pip package installed, you need to invoke that as pip3:

pip3 list
sudo pip3 install virtualenv

It means you need to install pip using this commmand-

sudo apt install python3-pip

if python3 is the only version of python installed then pip should invoke pip3 when used.

Create a symbolic link at /usr/local/bin/python3/pip which references to file /usr/local/bin/pip2.7.

sudo ln -s /usr/local/bin/pip2.7 /usr/local/bin/python3/pip 

Then change directories to ~/intel/computer_vision_sdk_2018.3.343/deployment_tools/model_optimizer/install_prerequisites and run sudo ./install_prerequisites.sh
