Installing the model involves doing some preliminaries, taking two installation steps, and then doing some clean-up:

• Preliminaries
• Step 1: Install/Update the Tax-Analyzer-Framework
• Step 2: Install/Update the MYI-Tax-Analyzer Model
• Clean-Up and Reminder

Preliminaries

Before taking the installation steps, create a new directory called MYI in your home directory. You can do this by opening an operating system command prompt window (by starting the cmd app on Windows, which should put you in your home directory). Make a note of the name of your home directory. Then enter the following command:
mkdir MYI
and then moving into that new directory using the
cd MYI
command. (Note that when entering a command, you need to press the Enter or Return key at the end in order to execute the command.) And finally, download the most recent MYI-Tax-Analyzer zip file and unzip it in the MYI directory. This zip file is encrypted (because it contains private data), so you will need a password from the model developers to unzip it. After doing this there will be a file whose name starts with myitaxanalyzer and ends with .whl.

Step 1. Install/Update the Tax-Analyzer-Framework

Do this by following these installation instructions.

Step 2. Install/Update the MYI-Tax-Analyzer Model

Execute the following commands in the MYI directory at the Anaconda Prompt (not in the Anaconda Navigator) if you are on Windows. On other operating systems, execute the following commands at the operating system command prompt.

• Activate the tafe environment by executing these two commands in the MYI directory:
  conda activate tafe
conda env update

• Create/update the myitaxanalyzer package on your computer by executing this command in the MYI directory:
  pip install --no-index --find-links=. myitaxanalyzer

To confirm that the myitaxanalyzer package was created/updated correctly, check that the command
myita --version
shows you the MYI-Tax-Analyzer version you downloaded. And check that the command
myita --test
generates a PASSED TEST message on the screen.

Clean-Up and Reminder

After taking the installation step(s), remove the MYI directory. The easiest way to do this is to use your operating system's graphical file management system to drag the MYI folder to the trash.

Remember that every time you want to use the model (by opening an Anaconda Prompt on Windows or an operating system command prompt on a non-Windows computer), you must activate the tafe environment by executing the
conda activate tafe
command.
