Install Matplotlib for Jetson nano with jets pack 4.6.1

Matplotlib installation will throw a lot of error if the Jetson setup is not done in order.

I would advise everyone to follow the instructions from the very beginning.

As first step clone the repository consists of all the scripts

git clone https://github.com/epratheeban/jetson_nano_setup.git
cd jetson_nano

As usual make the sh file executable

chmod +x 4.install_matplotlib.sh

then install

./4.install_matplotlib.sh
