kedro Virtual Environment

Avoid serious version conflict issues, and use a virtual environment [1] anytime you are running python, here are three ways you can setup a kedro virtual environment. https://youtu.be/ZSxc5VVCBhM - conda - venv - pipenv conda # [2] I prefer to use conda as my virtual environment manager of choice as it give me both the interpreter and the packages I install. I don’t have to rely on the system version of python or another tool to maintain python versions at all, I get everything in one tool. conda create -n my-project python=3.8 -y conda activate my-project python -m pip install --upgrade pip pip install -e src conda info --envs - stores environment in a root directory i.e. ~/miniconda3 - conda can use its own way to manage environments environment.yml - the python interpreter is packaged with the environment virtualenv # [3] Virtual env (venv) is another very respectable option that is built right into python, and requires no additional installs or using a different dis...

Kedro Install

Kedro comes with an install command to install and manage all of your projects dependencies. https://youtu.be/IWimEs-hHQg cd into your project directory and activate env # [1] You must start by having your kedro project either cloned down from an existing project or created from kedro new. Then activate your environment. Kedro New [2] this post covers kedro new kedro Virtual Environment [3] This post covers creating your virtual environment [4] for kedro install kedro # [5] Make sure you have kedro installed in your current environment, if you dont already have it. pip install kedro==0.17.4 pip-tools # [6] Kedro uses the pip-tools package under the hood to pin dependencies in a very robust way to ensure that the project will continue to work on everyone’s machine day, including production, day in and day out. No matter what happens to the dependencies you have installed. pip-compile # [7] The command that kedro uses from pip-tools is pip-compile. It will look at what yo...

Kedro Git Init

Immediately after kedro new, before you start running kedro install or your first line of code the first thing you should always do after getting a new kedro template created is to git init. https://youtu.be/IGba3ytf_6U git init # [2] Its as simple as these three commands to get started. git init git add . git commit -m init I don’t care if this project is for learning, if it will never have a remote or not, use git. References: [1]: /glossary/git/ [2]: #git-init

Kedro New

https://youtu.be/uqiv5LAiJe0 Kedro new is simply a wrapper around the cookiecutter templating library. The kedro team maintains a ready made template that has everything you need for a kedro project. They also maintain a few kedro starters, which are very similar to the base template. What is Kedro [1] Unsure what kedro is, Check out yesterdays post on What is Kedro. pipx # [2] I reccomend using pipx when running kedro new. pipx is designed for system level cli tools so that you do not need to maintain a virtual environment [3] or worry about version conflicts, pipx manages the environment for you. The kedro team does not reccomend pipx in their docs as they already feel like there is a bit of a tool overload for folks that may be less familiar with pipx kedro new I like using pipx as it gives you better control over using a specific version or always the latest version, unlike when you run what you have on your system depends on when you last installed or upgraded. Kedro Ne...

What is Kedro

Kedro is an unopinionated Data Engineering framework that comes with a somewhat opinionated template. It gives the user a way to build pipelines that automatically take care of io through the use of abstract DataSets that the user specifies through Catalog entries. These Catalog entries are loaded, ran through a function, and saved by Nodes. The order that these Nodes are executed are determined by the Pipeline, which is a DAG. It’s the runner’s job to manage the execution of the Nodes. https://youtu.be/Wf4rnFsaFFU --- What is Kedro [1] This is an updated version of my original what-is-kedro article --- Hot Take # [2] If you are doing a series of operations to data with python, especially if you are using something as supported as pandas, you should be using a framework that gives you a pipeline as a DAG and abstracts io. Orchestrators # [3] Like I said, kedro is unopinionated it does determine where or how your data should be ran. The kedro team does support the following ...

How I Kedro

https://youtu.be/bw5_FWDVRpU Ubuntu # [1] I recently switched over to using Ubuntu, it works well pretty much out of the box for me. I am using gnome with a dark theme. Gnome Terminal # [2] I am still using the built in default gnome terminal, it just works. It does all the things that I need it to do. It supports transparency renders my fonts and allows me to highlight things well. - One Dark Theme dotfiles # [3] You can find my dotfiles [4] on github. Feel free to read through and take anything that you find useful. I would encourage you not to steal them, but to integrate the parts that you want into your own dotfiles. dotfiles are a very personal thing. They are an extension of ones fingertips designed for how you think and type. zsh # [5] I use zsh as my default shell. I like to use it as my interactive shell. It works, and does a bit better with things like tab completion out of the box. starship # [6] I use the starship prompt for my shell. It works well out of the...

tmux show-messages

https://youtu.be/LLk94fKpGg4 As we push the limits of tmux further and further you are bound to end up in a situation where you are mashing down a hotkey and it’s just not doing what you want it to do, and you have no idea why. show-messages is a tmux command that can be used to show what tmux is actually doing behind the scenes. This might highlight any hot key conflicts you might have in your ~/.tmux.conf. man page for show-messages # [1] In case you wnat more information about show-messages, here is the man page. show-messages [-JT] [-t target-client] (alias: showmsgs) Show server messages or information. Messages are stored, up to a maximum of the limit set by the message-limit server option. -J and -T show debugging information about jobs and terminals.

tmux ta

https://youtu.be/nT0FA1RNZEs Now your creating, jumping, and killing sessions like a boss. You are slicing through projects with ease, let me show you one more thing that can be the cream on top of this silky smooth setup we have been working towards. Chris Toomey’s [1] Tmux Course # [2] This script is simply my fork of Chris Toomey’s tat script straight out of his course. It helps us create or jump to project specific sessions with ease. a directory of projects # [3] My version of the ta script will let you pass it a directory, and it will give you a fuzzy popup. ta ~/git setting up a keybinding # [4] bind C-g display-popup -E "ta ~/git" [5] default layout # [6] By default I have my projects open with a vertical split, vim is on top, with my file finder open and the lower split is set to just my terminal.

tmux display-message

https://youtu.be/utfLA6L8o5s You’ve got some long running tasks, and you’re trying to stay productive and knock tasks off that board, but you keep finding that your processes finish and you stay on other tasks for longer than you should. You were in the flow and just did not check back in on it. With display-message you can send yourself a notification when that long running task is complete. from the man page # [1] Here is a snippet of display-message from the tmux man page. I rarely need to do anything other than just display message, but there are other flags for it. display-message [-aINpv] [-c target-client] [-d delay] [-t target-pane] [message] (alias: display) Display a message. If -p is given, the output is printed to stdout, otherwise it is displayed in the target-client status line for up to delay milliseconds. If delay is not given, the message-time option is used; a delay of zero waits for a key press. ‘N’ ignores key presses and closes only after the delay e...

killing tmux

https://youtu.be/QWPyYx54JbE Now it’s time to switch gears, we are onto a different part of our day and there are just too many sessions running and we need to clean up shop. kill-server # [1] One viable option is to nuke the whole dang thing. I actually do this more than you might think. tmux kill-server save and commit your work diligently before kill-server kill-session # [2] A more reasonable option might be to kill a single session. # kills the current session tmux kill-session # kills the session named scratch tmux kill-session -t scratch choose-tree # [3] Killing sessions one by one from the command line can be a bit tedious, and involve more keystrokes than necessary. Another option built right into tmux is choose-tree. By default choose-tree is bound to prefix+s, that’s pressing control+b then s. Once you are in choose-tree, you can navigate around with your configured navigation scheme, press x to kill a session, or pane or window then y to confirm. You can also ...

tmux has-session

https://youtu.be/XucVVgGmesM I see you there, trying to script out your tmux layouts. Tryig to get each project setup just perfect with a script, but you keep stumbling over yourself with duplicate session error messages The has-session tmux command is a handy tool to prevent this duplicate session error message when scripting your tmux layouts. command line # [1] The command is pretty straight forward, you simply ask tmux if the session name you are looking for exists. tmux has-session -t "waylonwalker_com" How I navigate tmux in 2021 [2] for more information on how I navigate tmux, check out this full post Also check out the full YouTube tmux-playlist [3] to see all of the videos in this series.

tmux list-keys

https://youtu.be/Y1MYmL8ZolE Tmux list keys can be a useful tool to help remind you of what kebindings you have setup. You can search for them and scroll just like in tmux copy-mode. command line # [1] You can call list-keys from the command line but the interface is not very usable by itself. It might be nice to mix with grep or a pager in some circumstances. tmux list-keys tmux command line # [2] Running list-keys from within the tmux command line puts you into a much more pleasant copy-mode. list-keys default keybinging # [3] By default tmux comes with list-keys bound to prefix+?. bind-key ? list-keys list-keys man page # [4] You can see the additional flags provided by tmux in the man page for list-keys. list-keys [-1aN] [-P prefix-string -T key-table] [key] (alias: lsk) List key bindings. There are two forms: the default lists keys as bind-key commands; -N lists only keys with attached notes and shows only the ke y and note for each key. With the default form,...

tmux status-bar

https://youtu.be/mvgM8UH11_U The tmux status bar can be a handy tool to remind yourself where you are within tmux. It can also include a bunch of system information like battery status, cpu, mem, whatever you can get from the command line. Honestly I like to keep it minimal, and actually keep it turned off most of the time. I find that it helps a little bit for others to follow along if I keep it on in certain circumstances. show the status bar # [1] You can set a hotkey to show or hide the status bar. bind s set-option -g status bind C-s set-option -g status setting the background transparent # [2] I really want a minimal status bar with very little bling, I want it to get out of the way an not draw too much attention, so step one is to set the background to transparent. # default statusbar colors #―――――――――――――――――――――――――――――――― set-option -g status-bg default set-option -g status-fg colour240 setting default colors # [3] I want my status bar to somewhat match the rest of ...

tmux source-file

https://youtu.be/dDq0depPrTs So you have been tricking out that .tmux.conf, you’re looking for a silky smooth workflow that lets you fly through tmux with super speed, but every time you tweak out that .tmux.conf you have to restart your whole session. Not amymore, Let’s add this to the bottom of our tmux.conf so that you can see everytime it gets sourced. display-message "hello beautiful" command # [1] We can run this command from your shell to re-source your changed .tmux.conf tmux source-file ~/.tmux.conf It also works from the tmux command line. source-file ~/.tmux.conf tmux hotkey # [2] It’s very common to set this up as a keybinding so that you can do it easily without needing to memorize the exact command. bind -T prefix r source-file ~/.tmux.conf bind -n M-r source-file ~/.tmux.conf from vim # [3] This is my preferred way of re-sourcing my .tmux.conf. It sits quietly in the background, and I dont need to remember to do anything. If you are a vim user you can automat...

tmux fzf session jumper

https://youtu.be/DkJ9rb85LC0 Quickly getting between tmux splits is critical skill for productivity. You can get by with next or prev session for awhile, but if you have more than about three session you need something a bit more targeted. Full Screen selector # [1] I have used this fzf one keybinding for quite awhile, honestly I did not make it up, and cannot remember where it came from. It will open up a session picker in a new full screen window. bind C-j new-window -n "session-switcher" "\ tmux list-sessions -F '#{?session_attached,,#{session_name}}' |\ sed '/^$/d' |\ fzf --reverse --header jump-to-session --preview 'tmux capture-pane -pt {}' |\ xargs tmux switch-client -t" Popup selector # [2] Like with many of my keybindings I have swapped this one out for a popup version. It just feels so smooth. bind C-j display-popup -E "\ tmux list-sessions -F '#{?session_attached,,#{session_name}}' |\ sed '/^$/d' |\ fzf --reverse --header jump-to-session --preview 'tmux capt...

tmux next/prev session

https://youtu.be/8kZnjHPYnKU Now that we are splitting up work into their own sessions, lets talk about how to navigate between them without the command line. Navigating sessions is what kept me using a too many splits and windows workflow for far too long. It was rough, I was always tripping over panes and windows until I got too frustrated and just ran tmux kill-server to start on a new blank slate. bind -n M-P switch-client -p bind -n M-N switch-client -n How I navigate tmux in 2021 [1] for more information on how I navigate tmux, check out this full post Also check out the full YouTube tmux-playlist [2] to see all of the videos in this series.
