In this chapter, we will introduce you to the dvc package. If you don't use the environment for this book, you can install it with pip install dvc. The last part, visualization of the tree, will also require the pydotplus package.
As usual, all of the code is shared via a notebook, stored in the repository under Chapter14 (https://github.com/PacktPublishing/Learn-Python-by-Building-Data-Science-Applications).
