Simplified Run 2 Analysis: Setup

Prerequisites

To follow this lesson you need to start the python tools Docker container from the pre-exercises:

If you have already successfully installed and run the Docker example with python tools, then you need only execute the following command.

docker start -i my_python  #give the name of your container

If this doesn’t work, return to the python tools Docker container lesson to work through how to start the container.

Additional prerequisites - extra libraries

In order to use the coffea framework for our analysis, we need to install these additional packages directly in our container. We are adding cabinetry as well because we will use it later in our last episode. This can take a few minutes to install.

Once you have launched the Docker container, type the following commands in that environment (terminal).

pip install vector hist mplhep coffea cabinetry

Also, download this file, which is our starting schema. Directly in your /code area (or locally in your cms_open_data_python directory) you can simply do:

wget  https://raw.githubusercontent.com/cms-opendata-workshop/workshop2022-lesson-ttbarljetsanalysis-payload/master/trunk/agc_schema.py
