3. Install Python Libraries

Install required Python libraries using pip.

python3 -m pip install --user --upgrade numpy pandas matplotlib scipy seaborn posix_ipc

4. Install 3D Visualization Support (Optional)

For Qtenv with 3D visualization, install OpenSceneGraph and osgEarth packages.

sudo apt-get install -y libopenscenegraph-dev

5. Install MPI Packages (Optional)

To enable optional parallel simulation support, install MPI packages.

sudo apt-get install -y mpi-default-dev

6. Installing Omnetpp
