Does the Gaussian mixture modeling package from sklearn require normalization?

I’m using the Gaussian mixture model package from sklearn in python and I’m wondering if my data needs to be normalized and in what way (min max scaling, standard scaling, etc)? This is a dataset with both continuous variables like age and test scores as well as categorical variables like gender (as dummy binary variables). I can answer further questions in the comments. Thanks!

Pic2Pix: A script to turn pictures and drawings into sprites usable in 2d game engines.

I had a lot of trouble managing art assets as a solo dev in the first game jam I participated in, I ended up wasting far too much time making assets that simply werent worth the time. I wondered if my (mediocre) knowledge of programming in python could help on that front.



This script takes pictures and drawings, samples them, then filters the image based on the sample. All filtered pixels are simply turned transparent, leaving only the secrions that you (hopefully) desire, rendering an image that is usable as a sprite in 2d game engines like GameMaker.



The script is hosted on my Github. Have a looksee:

https://github.com/BobDev94/Pic2Pix



The target audience would be anyone who likes to doodle and turn their doodles into sprites. Or maybe people who want to turn themselves into a sprite. (Yes, the script can do that, provided they dont look the same as the background)



I think I've managed to create something unique. If not, drop me a link.

ReadingBricks - Flask app for searching personal Zettelkasten-like knowledge base

What does this project do?

Given a knowledge base in the supported format, this tools provides web interface for reading and searching notes. Features are as follows:

* Search by single tag

* Search by expressions consisting of tags, logical operators, and parentheses

* Full-text search with TF-IDF

* Links between notes

* Separate spaces for fields of knowledge

To use the tool, your notes must be converted to the special format. Namely, each note must be a Markdown cell in a Jupyter notebook. Such cells may have tags ('View -> Cell Toolbar -> Tags' in Jupyter) and may contain formulas in MathJax. One or more notebooks can be placed in a directory that represents a field of knowledge. A top-level directory with such nested directories is a knowledge base in the proper format.

Target audience

People who have their professional notes and want to easily navigate through them.

Alternatives

Obsidian

Pros:

* It is an end-to-end tool for both writing and reading

* It generates interactive graphs of connections between notes

Cons:

* It cannot search by tag expressions (only by tags or terms) - at least, without plugins

* My tool has more minimalist interface (just search bar and cloud of tags)

AWS Lambda Tutorial: Using Selenium with Chromedriver in Python

https://www.youtube.com/watch?v=8XBkm9DD6Ic

I created a concise tutorial on building a Docker image for deploying a Python Selenium package to AWS. One common challenge for beginners is downloading and configuring ChromeDriver, essential for using Selenium, a browser automation tool. In my video, I guide you through this process step-by-step. Additionally, I provide the necessary code in my Medium article linked in the video description to simplify your setup. Automating this functionality in AWS is quite impressive, and I hope this information proves valuable to many.

Consider subscribing or following me on Medium for more useful AWS tutorials in the future. I also do a bunch of IoT stuff!

Thanks, Reddit.

R Spider2-V: How Far Are Multimodal Agents From Automating Data Science and Engineering Workflows?

A new benchmark for multimodal AI agents, focused on real-world Dara Engineering tasks.

Project page: link, paper: link, code: link.

=====

TLDR: Autonomous LLM-agents can’t replace Data Engineers…yet. But at least we can track progress 🫡

Overview:

As AI technologies become more advanced, we need increasingly complex benchmarks to evaluate the quality of systems and measure progress. A distinct branch of benchmarks has emerged, focusing on working with professional tools/applications and websites (see WorkArena, WebArena, OSWorld).

In the Spider2-V project, a benchmark is being created to evaluate AI agents in data engineering. It consists of 494 tasks covering the entire work cycle:

Data Warehousing (tools like Snowflake, BigQuery)
Data Ingestion (e.g., Airbyte)
Data Transformation (e.g., dbt)
Data Visualization (e.g., Superset, Metabase)
Data Orchestration (e.g., Airflow, Dagster)

(and beloved Excel files, because who can do without them?)

If you have experience with data engineering, you understand that this is a substantial set, though it doesn't cover the entire zoo of solutions you might encounter.

Preparing each task took an average of 4 hours, so they are quite atomic and do not require very long horizon thinking. Tasks are divided into three levels of difficulty:

Easy (20%, no more than 5 steps to solve)
Medium (63%, 6-15 steps)
Hard (17%, 16-40

POST request help flask and react

Hey guys, I'm new to flask and have been trying to get my front end application to send some data to the flask server so the back end methods can use it but I keep getting these errors:

https://preview.redd.it/hpxc8rmnb6dd1.png?width=1028&format=png&auto=webp&s=28fa20a3d06fc11942898e3979c868f33916c6eb

I want the text that the user selects from the dropdown menu to be sent to the flask server because the backend main method requires a specific race name to fetch data from the database.



Here are the two files that may be useful:

Predict.js:

import React, { useEffect, useState } from "react";
import Loader from "./components/Loading";
import "./Predict.css";

function Predict() {
const data, setData = useState({});
const selectedRace, setSelectedRace = useState("");

useEffect(() => {
if (selectedRace !== "") {
fetch("/predict", {
method: "POST",
body: JSON.stringify({ race: selectedRace }),

Free hosting with 3GB?

I made a simple RAG app that uses an external LLM API, but the dependencies itself cross 2GB(llamaindex/langchain/huggingface). Is there any free option to host it? Or is there any way I can implement this functionality with more lightweight libraries?

in which ways is flask better than django?

hey everyone! I have to develop a project for my high school computer science class, and it takes up 30% of my final grade. anyways I decided to develop it with Flask because I'm an absolute noob at python haha, and I've heard that django is better for more experienced people.

however I need to write about why it is better then other API frameworks, like django, in a "technical" way.


so anyways, what are some technical advantages of flask compared to django or other API frameworks that I could say? or maybe I should choose another API framework that would ease my development? (I'm creating a website for a booking service)

If flask has async what would be the advantage of using an “async framework” like quart or starlette?

Flask-admin Wrong pagination after removing last row on the last page

Hi all. Essentially, after removal last entry on the last page of the table, the browser remains on now non-existent page displaying "There are no items in the table.". Refreshing the page doesn't help, as the browser still wants the same non-existent page. Can click on page with a previous number, then all good. I'd have expected a built-in check for that issue. Is there a workaround? Regards.

PySAPRPA: Automate SAP Processes Effortlessly with Python


Hi All,

What my project does:

Introducing PySAPRPA: a Python library that allows users to automate SAP processes in just a few lines of code. Leveraging the power of the GetObjectTree method, PySAPRPA automatically identifies and labels SAP objects, eliminating the need for manual script recording.

The library also allows for easy parameter setting with the set_parameters() method. Using the automatically identified objects, set_parameters() takes kwargs to set values for fields, buttons, and other interactive elements

Target audience:

Anyone who has ever used SAP. This library is very helpful for data mining, data entry, and testing because it’s simple, easy to debug, and takes minutes to setup.

Comparison:

While other libraries have similar value setting logic, I haven’t seen any others that automatically find and label objects, which is the most time consuming part of automating.

Here's an example code block automating t-code: MB51
import pysaprpa as pysap

session = pysap.connect_SAP()

conn = ObjectTree(session).start_transaction('MB51')

conn.get_objects().set_parameters(plant_TEXT=['100', '200'], movement_type_TEXT=['101', '102'], posting_date_TEXT=(7, 2024), layout_TEXT='EXAMPLE', database_FLAG=True)

conn.execute().get_objects().export(how='spreadsheet', directory='/fake/path', file_name=EXPORT.XLSX').end_transaction()

How to create flask REST API

Can someone explain to me like the proper way I can build a flask REST API, like a way that can be used in production.
I looked into many blogs and videos and saw some of them just using jsonify to return data and some of them using entirely different packages?
Which is the proper way?

Is there an aiohttp-based reusable api client?

In my previous job I had a custom aiohttp-based api client written in object oriented style. It was an incredibly easy thing to use, you just inherit from a class and then override all the things that are specific for a particular API. For example authentication and stuff like that. All the other things that are commonly used continue to be default.

But there is no such a library in Python. The only thing I found is aiohttp-api-client but this one seems to not be maintained and looks unpopular

Do you actually write different new clients with aiohttp from scratch every time you want to call a particular api?

I made a family dashboard using Flask (code included)

DinkyDash is a simple, customizable dashboard designed to display family-oriented information such as recurring tasks, countdowns to special events, and daily rotations. It’s perfect for mounting on a Raspberry Pi with a display in a common area of your home, providing at-a-glance information for all family members.

https://preview.redd.it/pd6rp9f51bdd1.png?width=1200&format=png&auto=webp&s=dd561fe822f610a4c55088612dcf95d6ea75401f

DinkyDash is great for quickly answering those questions that kids like to ask again and again and again and again.

“How many days till Christmas?”
“Who’s turn is it to take the trash out?”
“When is my birthday party?”

The dashboard shows:

Today’s date
Recurring tasks or roles (e.g., who’s turn it is to do the dishes)
Countdowns to important dates (birthdays, holidays, events)

DinkyDash is built with Flask and can be easily configured using a YAML file, making it simple to update and maintain without diving into the code.

Is it really best for backend only or is that just a myth

I've seen a couple of tutorials now specifying that Django is best used for backend and not for rendering html. It 'can' do html if you really want to but it's not great or something....

Well if I can, why shouldn't I? What's wrong with using Django for rendering my html? It even does jinja2 for templating.

The tutorials I watched just said it and didn't explain anything about their reasoning behind it (probably just copying others).

Is there any truth to it? And if so, what's the reason?
