Cancellation Token Pattern in Python

Hello! 👋 The Cancellation Token Pattern article is a pattern inspired by C#’s CancellationToken struct and Golang’s context package. The main idea of the pattern is to allow the user of an API to cancel its operations, but in order for this pattern to work, the API must be written with the cancellation token pattern in mind. To use the pattern, you need a class that represents a cancellation token. Here’s my simple version:...

Image tagging with Deep Learning

Hello everyone 👋, I’ve been playing with FastAI and deep learning for a week or so and I’ve decided to combine my passion for software with my passion for photography. I’m working on an app or maybe a library that allows you to generate tags for a photo. For an amateur photographer like me it’s quite useful as I don’t always have inspiration to write tags for my photos and sometimes the tags I write are inconsistent....

Deploy a FastAI model with FastAPI

Hello everyone 👋, In this quick post I’ll show you how to deploy a FastAI model using FastAPI. It’s a follow-up to my previous post from here and it is partially based on this FastAI lecture: Exporting the Model Before we create the API, we need to export the model as a pickle file. Add learn.export("<path>/cat_or_dog.pkl") with the full absolute export path at the end of the script: # ... learn = vision_learner(dls, resnet34, metrics=error_rate) learn....

FastAI GPU Support

Hello everyone 👋, This is my first blog post about AI, it’s a quick post on how to enable GPU support for the FastAI library. I have avoided getting into AI for some time now, I thought that it would involve lots of complicated math, and I was not sure that it would be worth the effort, I did not get very good grates in my college math classes 😅....

Overflowing Buckets

Hello everyone 👋, Today I want to share with you a problem I’ve encountered along my journey. The problem is fairly simple: You have a finite number of water units. You have a finite number of buckets. You need to distribute the water units into the buckets. Each bucket has a maximum capacity. When a bucket is full, the water overflows into the next two buckets by splitting evenly. You need to print the number of the buckets that are full....

How to install a specific Python version on Linux

Hello, 👋 In this article I will show you how to install Python versions on Linux using the following methods: compiling from source, dead snakes ppa and pyenv. To make things easier, if you want to follow along in an environment that you can break, you can create a local Kubernetes cluster using Minikube. Next, I’m going to use the following yaml file to create an Ubuntu pod: apiVersion: v1 kind: Pod metadata: name: ubuntu labels: app: ubuntu spec: containers: - image: ubuntu command: - "sleep" - "604800" imagePullPolicy: IfNotPresent name: ubuntu restartPolicy: Always Save the above yaml in a file ubuntu_pod....

LeetCode: Flood Fill

Hello, Here’s my solution for the flood fill problem, found on LeetCode. If you want me to write about certain topics please let me know in the comments, thank you! Link to the problem: """ An image is represented by a 2-D array of integers, each integer representing the pixel value of the image (from 0 to 65535). Given a coordinate (sr, sc) representing the starting pixel (row and column) of the flood fill, and a pixel value newColor, "flood fill" the image....

LeetCode: Add Two Numbers Python 3 iterative solution

[Problem Link] Hello, Here’s my solution for the add two numbers problem on LeetCode. Example: <strong>Input:</strong> (2 -> 4 -> 3) + (5 -> 6 -> 4) <strong>Output:</strong> 7 -> 0 -> 8 <strong>Explanation:</strong> 342 + 465 = 807. When doing problems on websites such as LeetCode, I like to code in my own IDE, that’s why you’ll see some additional helper functions besides the solution code. class Solution(object): def _get_append_func(self, root): _root = root def __add_to_list(value): nonlocal _root _root....
