Prerequisites

Before you begin, set up the following items:

To verify that you have the prerequisites installed, you can run a test that's similar to the following at the command line, as shown in the following example.

echo "
AWS CLI:"
which aws
aws --version 
aws configure list
aws sts get-caller-identity

echo "
Python (current environment):"
which python
python --version

echo "
Node.JS:"
which node
node --version 

echo "
Jupyter:"
where jupyter
jupyter --version
jupyter serverextension list
pip3 freeze | grep jupyter

The output should look something like the following. The directories vary by operating system and configuration.
