The Power of Quantization: Shrinking GPTUnleashing Speed

Imagine taking a powerful language model like GPT-2—capable of crafting stories, answering questions, and mimicking human text—and compressing it into a leaner, faster version without gutting its capabilities. This is the promise of quantization: a

Techniques for Field Validation in Django

Django form data validation is a key link in web development, ensuring that the user data collected meets application requirements. Django provides a variety of field validation methods, which this article will explain step by step. Using field parameters When defining Django form fields, you can usually specify validation rules directly through field parameters. For example, make sure the first_name field has a maximum length of 100 characters. Since it is a CharField, the max_length parameter can be used: from django import forms class PersonalInfo(forms.Form): first_name = fo

Implementing the Active Record Pattern in Python with SQLModel

Python developers often miss Active Record's elegant database interaction when migrating from Ruby on Rails to Python. While Python's SQLAlchemy (and therefore SQLModel) takes a different approach by default, we can implement a similar pattern to bring the convenience of Rails-style models to Python applications while maintaining type safety and following Python best practices. Active Record mode The Active Record pattern (popularized by Ruby on Rails) treats database records as objects with methods for database operations. It eliminates the need to use a separate repository class

Why FastAPI Full-Stack Template Is My Go-To for Modern Web Development

Python, although not the most modern programming language, is one of the most widely used languages today. An old Persian proverb: "A flower without thorns is a gift from heaven (گل بی‌خار خداست)" reminds us that everything in the world has flaws, and so do programming languages. Although Python has some performance issues (compared to compiled languages) and the notorious GIL (Global Interpreter Lock), its simplicity, large community, and rich library support more than make up for these shortcomings. Recent advances in Python's core technology have also paved the way for modern features like type hints and concurrency—features that were originally missing. Python 3.5 introduces type hints and

Portable Python Bundles on Windows

Packing the Python application and its environment to MS Windows for other users to use it, so that it can "run at any time" on any machine, which is a tricky task. This blog article describes my personal solution: I call it the Windows version of Python Bundle, which is similar to the virtual environment, but it can be transplanted between machines. Python Bundle is located at a virtual environment, conventional Python installation, and independent executable files provided by independent executable files created by tools such as Pyinstaller or Py2exe. Creating such a bundle does not require new tools. This is just a loose and lightweight agreement.

Python Logging: loguru vs logging

Python logging library comparison: logging vs loguru 1. Loguru simplifies logging Logging is a vital tool in Python development. It helps developers record program running status, debug problems, and monitor system health. Python comes with a logging library. However, as needs changed, many people started using loguru as an alternative. This article will compare these two libraries and help you choose a more suitable logging solution. Loguru is a popular third-party logging library. It has become an effective tool for logging by simplifying the configuration process, supporting chain calls, and providing richer functions.

How to create a model from my data on Kaggle

This tutorial demonstrates how to use the FastAI library to train an image classification model to distinguish between cats and dogs. We'll go step by step, from data preparation to model training and usage. Step 1: Data preparation Image search function: First, we define a function for searching images from the DuckDuckGo search engine. This function accepts keywords and the maximum number of images as input and returns a list of image URLs. import os iskaggle = os.environ.get('KAGGLE_KERNEL_RUN_TYPE', '') if iskaggle: !pip install -Uqq fasta
