Best way to manage sockets with django

Hey, what is the best way to manage sockets with Django? I tried using Daphne, but it didn’t work well for me. It was working fine for a while, but then I had trouble restarting the Daphne server, even after restoring the configuration to the last working state. I’ve had enough of Daphne. Are there any good alternatives?

Celery is making me go insane

To preface this, I am using WSL2 Ubuntu in windows 11 for my development environment. I use visual studio code for my code editor.

I wanted to integrate Celery and Redis in a project I was working on, but I keep encountering this issue. Even if the task had already completed and is successful (based on Flower monitoring), when I try to retrieve the task result or task status in my flask app using AsyncResult and .get() it just loads infinitely and shows the status as PENDING and the result as NULL.

Now, I created a new stripped down flask app just to isolate the issue. And even with just a basic Flask app setup I am still experiencing it. I have been messing around with this for more than 48 hours now and it's driving me crazy.

Here are some code snippets from the stripped down flask app:

**\_\_init\_\_.py**

import os, time
from datetime import timedelta

from flask import Flask
from dotenv import load_dotenv
from .extensions import prepare_extensions, celery_init_app

load_dotenv()
app = Flask(__name__)

Beautiful Pancakes - A simple way to implement file writing and opening on PyQt's QGraphicsScene

Hey all!

# I am a relatively new Python programmer with experience in PyQt blah blah blah...

Anyways, when I was creating QGraphicsScene test files, I wanted to figure out a way to write QGraphicsItems to files, and then read those files to open them. This really doesn't exist for PyQt/PySide, as I have only found ways to do that in C++ Qt.

*So thats why I just finished Beautiful Pancakes today, [here's the repository\](https://github.com/ktechhydle/beautiful_pancakes).*

# What my project does

Implements file reading and writing for QGraphicsScenes with full support for file dialogs. PySide6 and PyQt5 supported.

# Target audience

It's great for basic to complex scenes, but I will try to update it and eventually make it work for advanced and performance heavy scenes.

# Comparison

There are alternatives, but most are written in C++. I have yet to find a PyQt version.

All serialization/deserialization is done in Pickle.

I hope you enjoy.

vectorized CIE distance in basiccolormath 3.0

[ShayHill/basic\colormath: Simple color conversion and perceptual (DeltaE CIE 2000) difference (github.com)](https://github.com/ShayHill/basiccolormath)

# What My Project Does

Everything I wanted to salvage from the [python-colormath](https://github.com/gtaylor/python-colormath/tree/master) library ... with no numpy deps and 14x speed.

* Perceptual (DeltaE CIE 2000) and Euclidean distance between colors
* Conversion between RGB, HSV, HSL, and 8-bit hex colors
* Simple, one-way conversion to Lab
* Some convenience functions for RGB tuples and 8-bit hex color strings

# Target Audience

Meant for production.

# vectorized functions

If you have numpy installed in your env, basic\colormath will provide vectorized versions of most functions.

|Function|Vectorized Function|
|:-|:-|
|float_to_8bit_int|floats_to_uint8|
|get_delta_e|get_deltas_e|
|get_delta_e_hex|get_deltas_e_hex|
|get_delta_e_lab|get_deltas_e_lab|
|get_euclidean|get_euclideans|
|get_euclidean_hex|get_euclideans_hex|
|get_sqeuclidean|get_sqeuclideans|
|get_sqeuclidean_hex|get_sqeuclideans_hex|
|hex_to_rgb|hexs_to_rgb|
|hsl_to_rgb|hsls_to_rgb|
|hsv_to_rgb|hsvs_to_rgb|
|rgb_to_hex|rgbs_to_hex|
|rgb_to_hsl|rgbs_to_hsl|
|rgb_to_hsv|rgbs_to_hsv|
|rgb_to_lab|rgbs_to_lab|

# Comparison

Sadly, python-colormath has been abandoned, long enough now that a numpy function on which it relies has been not only deprecated but removed. If you still need to use python-colormath, patch np.asscalar:

import numpy as np
import numpy.typing as npt

def patchasscalar(a: npt.NDArraynp.float64) -> float:
"""Alias for np.item(). Patch np.asscalar for colormath.

:param a: numpy array
:return: input array as scalar
"""

Okrolearn a machine learning library which is for powerful analzys and training while being light

I’m excited to share a project I’ve been working on called okrolearn. Which was created to allow for powerful analazys features and neural network training capabilities my own ideas while being as light as possible.

Target audience:

Machine learning enjoyers, mobile machine learning coders, data scientists.

Comparison:

Compared to things like pytorch or tensorflow it has better macOS support, better cpu usage, is way more light weight, is designed for lighter models, has features that these don't have,

What my project does:

* Trainin machine learning models

* Deploy models

* Is light

* Have analazys features such as correlation heatmaps, plotting kmeans, histograms, plotting losses, paramaters, etc.

* Manage layers for models, convolutional, l regularisation, batch, instance, dropout normalisers

* Have gpu support, custom kernels on gpu

* Have experimental features such as suggesting architecture and layers based on temperature and input data

* Have better macOS support

* Have better cpu performance

Why did I create this for simpler models or models that had to be lightweight tensorflow or pytorch didn't do a good job, I also wanted this library to be mainly in python, also converting pytorch tensors back to numpy arrays for me to analyse them was to slow and annoying, there were also ideas that I wanted to implement on

Make-like task runner in Python

I made a complete Make-like build tool & task runner in Python.

I wanted to adopt Make's scheme of rules, targets, recipes, and dependencies mainly because it's simple, intuitive, and widely used.

Inspiration for the project came from using doit for similar tasks, and growing tired of the confusing API. There are other similar tools out there, but what I wanted was a lightweight, easy-to-use, flexible, and well documented task runner & dependency resolver for a data processing pipeline in Python.

GitHub: https://github.com/gird-dev/gird

Simple example & comparison with doit: https://stackoverflow.com/a/77752742

Django site ready - but having trouble deploying in azure as web app or docker (inexperienced)

Hey y’all! Been working on a project and ready to drop the MVP on azure for UAT. But even though I’m azure fundamentals certified I am lacking in the deployment department and can’t quite get my azure web app up and clearing a 200 status code. Looking for help or even a recommendation for experienced help to get me familiar with the process.

Here’s where I’m at:
1. Django project with 2 apps, email and Postgres DB, all working in dev
2. Have a “deployment.py” file that is referenced if os.environ() finds an azure host name, otherwise debug version of settings.py is used
3. Deployed the app via GitHub repo connected to azure. In the deployment logs I get a warning that “Django must be in the requirements.py file” but it is. No other errors seen
4. When accessing the webpage using the azure temporary url I get a 504 error.
5. I can’t troubleshoot much further since I can’t find where other logs are located and the documentation I have found is outdated and doesn’t match the current azure UI

Any help or leads for troubleshooting are appreciated! Please feel free to ask for more info if I haven’t provided it!

How to schedule a daily recurring function?
