Add New Dependencies to Your Kedro Project

As you work on your kedro projects you are bound to need to add more dependencies to the project eventually. Kedro uses a fantastic command pip-compile under the hood to ensure that everyone is on the same version of packages at all times, and able to easily upgrade them. It might be a bit different workflow than what you have seen, let's take a look at it.

git status

Before you start mucking around with any changes to dependencies make sure that your git status is clean. I'd even recommend starting a new branch for this, and if you are working on a team potentially submit this as its own PR for clarity.

git status git checkout main git checkout -b add-rich-dependency
Enter fullscreen mode Exit fullscreen mode

requirements.in

New requirements get added to a requirements.in file. If you need to specify an exact version, or a minimum version you can do that, but if all versions generally work you can leave it open.

# requirements.in
rich
Enter fullscreen mode Exit fullscreen mode

Here I added the popular rich package to my requirements.in file. Since I am ok with the latest version I am not going to pin anything, I am going to let the pip resolver pick the latest version that does not conflict with any of my dependencies for me.

build-reqs

The command kedro build-reqs will tell kedro to recompile the
requirements.txt file that has all of our dependencies pinned down to exact
versions. This ensures that all of our teammates and production workflows use the same exact versions of packages even if new ones are released after we installed on our development machines.

git add

Now that we have our new dependencies ready to go commit those to git, and submit a PR for them if you are working on a team. This is a good way to document the discussion of adding new dependencies to your teams project.

git add requirements.in git add requirements.txt git status git commit -m "FEAT updated dependencies with rich" git push
# go make a pr
gh pr create --title "feat add rich to dependencies" --body "I added rich as a dependency, and ran pip-compile"
