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...

I started making stories as kind of a brain dump a few times per day and posting them to [LinkedIn](https://www.linkedin.com/in/waylonwalker/(https://www.linkedin.com/in/waylonwalker/). Here are the last 11 days of stories. I store all the stories on my website with the hopes of doing something with them on my own platform eventually. For now it makes it easy to make these posts. cd static/stories ls | xargs -I {} echo '' Stories 10-10-2020 - 10-21-2020 # [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] References: [1]: #stories-10-10-2020---10-21-2020 [2]: https://waylonwalker.com/stories/TIL-kedro-sorts-nodes.png [3]: https://waylonwalker.com/stories/disable-base-pip.png [4]: https://waylonwalker.com/stories/discovered-social-cards.png [5]: https://waylonwalker.com/stories/find-kedro-de1-contributor.png [6]: https://waylonwalker.com/stories/hacktoberfest-2020-kedro-538-tests-pass.png [7]: https://waylonwalk...

I was 20 commits into a hackoberfest PR when I suddenly realized they they all had my work email on them instead of my personal email 😱. This is the story of how I corrected my email address on 19 individual commits after already submitting for a PR. - Change the email for this repo [1] - Prepare for rebasing [2] - start the rebase [3] - 🛠 Fix First wrong Commit [4] - Fix all commits [5] - Done [6] - ReCap [7] Change the email for this repo # [1] stop the bleeding Before anything else set the email correctly! cd kedro git config user.name "Waylon Walker" git config user.email [email protected] Prepare for rebasing # [2] First thing is to find how many commits back this mistake goes. I opened up the git [8] log, and saw mine went back 19 commits. I rolled back 20 just to be sure. $ git log ... commit a355926b9d7ec4c05659adaa254beefbdb036332 Author: WaylonWalker <[email protected]> Date: Sat Oct 17 10:28:59 2020 -0500 give name of function inside incorrect parameters erro...

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...

Today I ran into an issue where we had a one-off script that just needed to work, but it was just chewing threw memory like nothing. It started with a colleague asking me How do I clear the memory in a Jupyter notebook, these are the steps we took to debug the issue and free up some memory in their notebook. How do I clear the memory in a Jupyter notebook? Pre check the status of memory # [1] There are a number of ways that you can check the amount of memory on your system. The easiest is not necessarily my first go to is free… literally free. check for free space $ free -h total used free shared buffers cached Mem: 15G 15G 150M 0B 59M 8.7G Generally my first go to is a bit more graphical, and not available on a stock stystem, but far more useful…. htop. htop [2] is a terminal process explorer that shows cpu usage, mem usage, and running processes. htop sudo apt-get install htop # install it from your package repo htop [3] First step throw more swap at it # [4] Often be...

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. A simple fix is to run this one-liner.
