Codeit Bro Interview

[1] use this profile image Please share your professional role as a data scientist? [Also feel free to share about your personal projects, publications, etc.] I graduated with a Mechanical Engineering Degree 8 years ago. Much of my work early in my career [2] was wrapped around analyzing larger datasets for my group to understand quality, drive changes to improve quality or prove that quality was already good. My first eight years as a working professional. This day 8 years ago I started my first day as a Mechanical Engineer. I am so grateful for this journey that I have been able to have. There is no way that I... Jun 19, 2020 [3] Three years ago I made the switch to Data Science and have loved every minute of it.

I talk a lot about the mindset of always learning, sharing knowledge, and communicating in my newsletter [4] What are the most difficult chall...

reasons-to-kedro

There are many reasons that you should be using kedro. If you are on a team of Data Scientists/Data Engineers processing DataFrames from many data sources should be considering a pipeline framework. Kedro is a great option that provides many benefits for teams to collaborate, develop, and deploy data pipelines What is Kedro [1] Starter Template # [2] Kedro makes it super easy to get started with their cli that utilizes cookiecutter under the hood. conda create -n my-new-project -y python=3.8 kedro new kedro install kedro run Create New Kedro Project [3] read more about how to start your first kedro project here Collaboration # [4] Kedro provides many tools that help teams collaborate on a single codebase. While writing monolithic scripts it can be easy to pin yourself in a corner where it is difficult to have multiple people making changes to the notebook/script at the same time. Kedro helps guide your team to break your project down into small pieces that different members o...

Reasons to Kedro

Reasons to Kedro # [1] - collaboration - Sharable catalog - small nodes over monolithic notebooks - catalog - easily load anything without needing to run - No need to write read/write code - pipeline - No need to keep execution order in your head - easily run a slice of a pipeline - plugins - pip install - make your own - hooks - flexible expandable cli Reasons Not to Kedro # [2] - Already utilizing another DAG framework - Data is not in a widely supported format - Micro short-lived project - Large Project / Deadline - Use a lower profile project to learn first - Team not willing to change - Need minimal dependencies - God Project - kedro owns everything??

What's New in Kedro 0.16.6

Kedro 0.16.6 [1] is out! Let’s take a look through the release notes Deployment Docs # [2] This is really exciting to see more deployment options coming from the kedro team. It really shows the power of the framework. The power of some of these orchestrations options is incredible. - Argo [3] - Prefect [4] - Kubeflow [5] - Batch [6] - SageMaker [7] Most of them hinge on a sweet combination of the kedro cli, docker image, and the pipeline knowing your nodes dependencies. Argo, Prefect, and Kubeflow have an interesting technique where they translate the pipeline and its dependencies from kedro to their language. Batch uses the aws cli to submit jobs, one node per job, and listen for them to complete. It will submit all nodes with completed dependencies at once, meaning that we can get some massive parallelization. I did a quick and dirty test of one of these by simulating the technique in a bash script and saw a 40 hr pipeline finish in about 1 hour. I am excited to get thi...

Designing a "Router" for kedro

nodes_global # [1] I released a router-like plugin for kedro back in April 2020. This was not the first design, the idea actually came from one of the QB folks who taught me kedro nearly a year before. We were assembling our pipelines with something called nodes_global. It worked fairly well but did have some issues around being set as a global variable. But… One thing in particular that it did not lend itself well to was being able to create a packagable pipeline that I could pip install and append into any of my existing pipelines. Something I am still trying to work out, maybe I don’t need this. I think I have it working for our internal pipelines and it seems like the way to go, but we don’t necessarily end up using it. Also… With this pattern all of the nodes needed to be importable by the module containing nodes_global. I find that this becomes a big hurdle for new pipelines coming from jupyter to overcome and can be most infuriating when their nodes aren’t getting ran af...

Strip Trailing Whitespace from Git projects

A common linting error thrown by various linters is for trailing whitespace. I most often use flake8. I generally have [pre-commit](https://waylonwalker.com/pre-commit-is-awesome hooks setup to strip this, but sometimes I run into situations where I jump into a project without it, and my editor lights up with errors.

Chrome Extensions I use

Creating Reusable Bash Scripts

Bash is a language that is quite useful for automation no matter what language you write in. Bash can do so many powerful system-level tasks. Even if you are on windows these days you are likely to come across bash inside a cloud VM, Continuous Integration, or even inside of docker. I have three techniques that help me write more composable bash scripts. - functions [1] - Arguments [2] - positional arguments [3] - All Arguments [4] - Error Handling [5] - main script [6] --- Functions # [1] Break scripts down into reusable components Functions in bash are quite simple. They are something that I wish I would have started using long ago. They make your code much more reusable. I often use them in my aliases as well since they can simplify the process and allow more flexibility. syntax #!/bin/sh # hello_world hello_world () { echo "hello world" } Source the file to load the function and run it from the terminal. run it source hello_world hello_world outputs hello world ...

Three things to Automate with Python using Pandas

Here are three things that I see my non programming counterparts doing every single day. These really sum up so much of what folks do within an office.

Focus on Value Add Operations # [1] Lets face it, stitching together spreadsheets is zero value add by itself, but if you can see something in the data and take action on it, this can be huge value add to your company. Learning just a bit of python will help focus more of your attention on “value add operations” and leave the mundane stuff to your computer. Merge a directory full of spreadsheets into one # [2] I see this one all the time. One team gets a spreadsheet from another team once per month and they need to stich all the pieces together.

How to Install miniconda on linux (from the command line only)

miniconda is a python distribution from continuum. It’s a slimmed-down version of their very popular anaconda distribution. It comes with its own environment manager and has eased the install process for many that do not have a way to compile c-extensions. It made it much easier to install the data science stack on windows a few years ago. These days windows are much better than it was back then at compiling c-extensions. I still like its environment manager, which installs to a global directory rather than a local directory for your project. Installing miniconda on Linux # [1] Installing miniconda on Linux can be a bit tricky the first time you do it completely from the terminal. The following snippet will create a directory to install miniconda into, download the latest python 3 based install script for Linux 64 bit, run the install script, delete the install script, then add a conda initialize to your bash or zsh shell. After doing this you can restart your shell and conda will...

Review of the git-auto-commit-action

It’s a really cool GitHub action that will automatically commit files changed during the action. I was using this to render a new readme based on a template. Check out the repo for git-auto-commit-action [1]. It’s a really cool GitHub action that will automatically commit files changed during the action. I was using this to render a new readme based on a template. This has been by far the easiest way to commit back to a repo that I have seen. Other patterns often require fully setting up the git [2] user and everything. While it’s not all that hard, this action already has all of that covered. You must give it a commit message and thats it. Optionally you can configure a number of things. Its possible to configure the commit_user_name, commit_user_email, and commit_author. I often also scope the file_pattern to a certain subset of files. --- Getting Started with GitHub Actions Github actions are written in configuration files using the YAML syntax.

What's New in Kedro 0.16.4

If we take a look at the release notes [1] I see one major feature improvement on the list, auto-discovery of hooks. ## Major features and improvements * Enabled auto-discovery of hooks implementations coming from installed plugins. This one comes a bit surprising as it was just casually mentioned in #435 [2] [2] Think pytest # [3] As mentioned in #435 [2] this is the model that pytest uses. Not all plugins automatically start doing things right out of the box but require a CLI argument. simplicity # [4] It feels a bit crazy that simply installing a package will change the way that your pipeline gets executed. I do like that it requires just a bit less reaching into the framework stuff for the average user. Most folks will be able to write in the catalog and nodes without much change to the rest of the project.
