<jupyter_start><jupyter_text>Install librariesIt takes some time to install the python libraries for the first time, but this only needs to be done once for all the coding exercises in this lesson.  Please run this code in a separate tab while you continue watching the videos.  Once you get to the first coding exercise of the lesson, if this notebook is done installing, then you won't have to wait for the installation to start running the code in that exercise.<jupyter_code>import sys
