SciPy 1.15.0 released: Full sparse array support, new differentiation module, Python 3.13t support

# SciPy 1.15.0 Release Notes

SciPy 1.15.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.15.x branch, and on adding new features on the main branch.

This release requires Python 3.10-3.13 and NumPy 1.23.5 or greater.

# Highlights of this release

Sparse arrays are now fully functional for 1-D and 2-D arrays. We recommend that all new code use sparse arrays instead of sparse matrices and that developers start to migrate their existing code from sparse matrix to sparse array: [`migration_to_sparray`](https://scipy.github.io/devdocs/reference/sparse.migration_to_sparray.html). Both `sparse.linalg` and `sparse.csgraph` work with either sparse matrix or sparse array and work internally with sparse array.
Sparse arrays now provide basic support for n-D arrays in the COO format including add, subtract, reshape, transpose, matmul, dot, tensordot and others. More functionality is

Interactive Image Background Remover (open source Photoroom Alternative)

https://github.com/pricklygorse/Interactive-Image-Background-Remover

## What My Project Does

Removes backgrounds from images both automatically and interactively. The key feature of this is you can click parts of the image to remove them, refine and fine tune the background removal, instead of just getting an output and that is it. The workflow is building up a mask from parts of the image, using open weights background removal models to achieve this. It can use both unguided whole-image models (u2net, disnet, rmbg, birefnet) and guided models (segment anything variants). There is also a manual paintbrush if the models struggle.

I've also implemented background colours, simple blurred background and drop shadow effects.

My aim is to work vaguely towards an open source local Photoroom alternative. Its a very very long way from that, but as is, it should be functional for most background removal tasks that many other services struggle with.



## Target Audience

Anyone who needs to remove backgrounds from photos, and wants a "click to remove" workflow, instead of relying on outputs of unguided whole-image removal services. It is a hobby project tailored around my use cases but hopefully stable enough for sharing. The code is pretty rough in places as its my first GUI app

So is Django + Vue a good stack?

Hi, I have been stuck in tutorial hell for a while now and decided to build a project for my school. Essentially, its a webpage will allow students to interact with teachers and each other. Can't say much more than that because it is a pretty good business idea and I want to monetise it in the future.

It will need an authentication system, and it will involve the users updating information (so not view only, its dynamic), so a database would be necessary. Because students are using it there has to be no security issues, and it has to be visually pleasing.

I found a teacher at my school that is willing to help me out. He has some experience in Vue, and because I am reasonably familiar with Python, I thought of handling the back end with Django and the front-end with Vue, but I have come across people saying that this is an inefficient stack that doesn't make the best of either technology.

I also tried Firebase initially but couldn't get it to work with Vue because of a ton of "vulnerabilities" that I had no idea how to get rid of, no matter how many times a ran the

Phitter - A Python library for Statistical Distribution Fitting

I just encountered [Phitter](https://github.com/phitterio/phitter-kernel), a Python library that makes statistical distribution fitting both powerful and intuitive. Not my project, but looks very interesting!

# What is Phitter?

Phitter is a robust Python library that helps you identify and fit the most appropriate statistical distributions to your datasets. Think of it as your Swiss Army knife for probability distribution analysis - whether you're working with continuous or discrete data, Phitter has got you covered.

# Key Features:

* Support for 80+ probability distributions (both continuous and discrete)
* Three goodness-of-fit tests (Chi-Square, Kolmogorov-Smirnov, Anderson-Darling)
* Beautiful visualizations (histograms, PDFs, ECDFs, Q-Q plots)
* Parallel processing support for large datasets
* Comprehensive documentation and modeling guides

# Show Me The Code!

Here's how simple it is to get started:

import phitter

# Basic usage
data = [your_data_here]
phi = phitter.PHITTER(data)
phi.fit()

# Get a summary of the top k distributions
print(phi.summarize(k=5))

# Plot the results
phi.plot_histogram_distributions() # Shows fitted distributions
phi.plot_ecdf() # Empirical Cumulative Distribution Function

How to create a dynamic formset by reading data from an uploaded file and then allow it to be modified before final submission and storage

Hi,

I have the following usecase:

1) Users can upload a csv file of their bank transactions.

2) The file is parsed and converted into transactions instances and categorized. The categories and list of transactions are shown to the user.

3) The user can then make some modifications (e.g., change categories) and finally submit the formset leading to all transactions being saved in the database.


I am currently struggling with the (3) step and not able to get a formset work which is populated from data not yet in database.

Does anyone have examples of how to solve this? I can share code snippets of course.

Are there better alternatives for this problem? May be HTMX, given that formsets have such bad reviews.

p.s. my current approach is as follows:

I handle the uploaded csv file in the POST view and extract transactions. Using these transaction instances, I populate a formset and then render it. However, when I submit the formset no data is saved.

Any help highly appreciated!

Accessing foreign key in a template.

I'll use the typical models given with Django examples and explain the problem I'm having.

class Author(models.Model):
name = models.CharField()

class Book(models.Model):
name = models.CharField()
author = models.ForeignKey(Author)

I'm listing the books out in a template and need to access the author of each book. I've tried {{book.author.name}} and it doesn't work. I've also seen recommendations to use {{book.author_set.all.0}}, but that doesn't work either. Any guidance on whether or not this is possible and how to go about it is appreciated.

Dataclass Wizard: V1 Opt-in Out Now!

# What My Project Does

The Dataclass Wizard simplifies working with Python dataclasses by offering seamless de/serialization to/from JSON. With robust support for features like aliases, recursive types, and a magic-like user experience, this library transforms how you interact with data models in Python.

Whether you’re working with simple or complex data structures, Dataclass Wizard eliminates boilerplate and optimizes performance, making it easier than ever to handle data.

# Target Audience

Dataclass Wizard is designed for Python developers who:

Work with `dataclasses`, `TypedDict`, or `NamedTuple`.
Need to serialize or deserialize JSON effortlessly.
Value performance and clean, readable code.
Want advanced features like aliasing, recursive type support, or handling complex types.

From API development to data pipelines, if you’re tired of manual conversions or inefficient workflows, this library is for you.

# Comparison

Compared to alternatives like Pydantic, Dataclass Wizard offers:

A lightweight and pure Python solution with minimal dependencies.
Support for dataclasses out of the box, rather than relying on custom models.
Better performance for specific tasks such as handling `NamedTuple` or recursive types.

My first python package - MathSpell. Convert numbers to words contextually.

Hi everyone,

I wanted to share a Python package I recently (yesterday) developed called mathspell. It was created to assist with number-to-word conversions in my main project.

# Target Audience:

I thought it might be useful for others working on data preprocessing tasks for applications such as text to speech.

# What my project does:

Context aware conversion of numbers into words, handling ordinals, currencies, and years without needing manual configuration.

# Comparisons

Easy to Use: You can simply pass your text to the `analyze_text` function.
Saves Time: It removes the complexity of setting up num2words for different contexts. It does the heavy lifting by configuring different use cases with reliable libraries (num2words, spaCy, re)

# Usage Example

from mathspell import analyzetext

text = "I have $100 and I was born in 1990. This is the 1st time."
transformed = analyzetext(text)
print(transformed)


Output:

I have one hundred dollars and I was born in nineteen ninety. This is the first time.


# Current Limitations

English Only: Currently designed for English. Supporting other languages would require additional work.
Early Development Stage: I developed this

I Made a Django Deployment Tutorial with PythonAnywhere—So Grateful It Exists!

I love PythonAnywhere. When I was learning Python, it was a total game-changer—being able to open a browser anywhere and just code was amazing. It gave me a safe space to experiment and learn without the hassle of setting things up.

What makes me appreciate it even more now is how much they give back. Their free tier is fantastic, and their paid plans are affordable. They’ve made coding so accessible, and I’m genuinely grateful for that.

Back when I was a complete Django newb, I tried deploying on it but struggled a little—Looking back I think it was probably a typo in the WSGI configuration which made me assume it was too complicated and I switched to other services.

However, more recently I came to realize how simple PythonAnywhere makes it. Features like persistent disks (even in the free tier!) make it such a practical choice, especially for beginners.

A couple of nights ago, I stayed up late to create a "code with me" style tutorial where I deploy a simple Django e-commerce project. If you’re new to deployment or just curious about PythonAnywhere, I hope this helps!

Sorting Algorithm Visualizations! (with sound) (+ some DSA implementations)

(TLDR, Project here --> https://github.com/pythonioncoder/DSA-Visualizations)

Hey guys!

I just finished a DSA course and decided to implement some of the stuff I learned in a GitHub repo. I also made visualizations for the sorts I learned, so feel free to check it out! It's been a long-time dream of mine to make sorting algorithm visualizations like the famous ones online, but I could never get the hang of it. So, with that in mind, I hope you can appreciate the stuff I've created!


What the project is:

A GitHub repo full of DSA implementations from Linked Lists to BSTs, alongside various sorting algorithms and visualizations implemented in Python using Matplotlib, Numpy, and Pygame.



Target Audience:

Whoever wants to learn more about DSA and Sorting Algos in Python, or just wants to see some cool animations using Matplotlib.


Comparison:

Similar to Timo Bagman's 'Sound of Sorting' project that went viral on youtube a while ago, except on Python.

Introcuding kokoro-onnx TTS

Hey everyone!

I recently worked on the kokoro-onnx package, which is a TTS (text-to-speech) system built with onnxruntime, based on the new kokoro model (https://huggingface.co/hexgrad/Kokoro-82M)

The model is really cool and includes multiple voices, including a whispering feature similar to Eleven Labs.

It works faster than real-time on macOS M1. The package supports Linux, Windows, macOS x86-64, and arm64!
