D Conceptually/On a Code Basis - Why does Pytorch work with CUDA out of the box, with minimal setup required, but tensorflow would require all sorts of dependencies?

Hopefully this question doesn't break rule 6.

When I first learned machine learning, we primarily used TensorFlow on platforms like Google Colab or cloud platforms like Databricks, so I never had to worry about setting up Python or TensorFlow environments myself.

Now that I’m working on personal projects, I want to leverage my gaming PC to accelerate training using my GPU. Since I’m most familiar with the TensorFlow model training process, I started off with TensorFlow.

But my god—it was such a pain to set up. As you all probably know, getting it to work often involves very roundabout methods, like using WSL or setting up a Docker dev container.

Then I tried PyTorch, and realized how much easier it is to get everything running with CUDA. That got me thinking: conceptually, why does PyTorch require minimal setup to use CUDA, while TensorFlow needs all sorts of dependencies and is just generally a pain to get working?

I made a FOSS feature rich Python template with SOTA tools, security, CI/CD, yet easy to use

## Introduction

Hey, created a FOSS Python library template with features I have never seen (especially in Python development) and which IMO is the most comprehensive, yet focused on usability (template setup is one click and one `pdm setup` command to setup locally, after that only `src`, `tests` and `pyproject.toml` should be of your concern), but I'll let you be the judge.

R Reinforcement Learning Teachers of Test Time Scaling

TL;DR: The raw outputs of our new 7B RL model provide stronger distillation and cold-starting than the filtered and post-processed reasoning traces of orders-of-magnitude larger LMs such as DeepSeek-R1.

How did we achieve this result? We turned the RL task on its head. Rather than training to solve challenging problems from scratch, we optimize our models to generate clear, step-by-step "explanations" to "teach" their students, providing both the problem’s question and its solution already in their input prompt.

This makes the RL training task much easier and also directly aligned with downstream distillation, allowing us to train tiny 7B teachers, boosting the performance of even larger 32B students.

How to implement multi-tenancy with django-tenants for my SaaS ?


Hey devs,

I'm building a SaaS healthcare CRM targeting small or solo medical practices. I want each clinic (tenant) to have its own isolated database schema using django-tenants.

So far, I’ve done the following:

Created a Clinic model using TenantMixin and set autocreateschema = True

Added a Domain model for routing using DomainMixin

Created a custom User model for each tenant

Installed and configured django-tenants


But I still have questions to clarify the right implementation:

1. How should I structure the signup process?
Should I register the tenant (clinic), then switch to that schema and create users?


2. Should the user model be shared (in the public schema) or be tenant-specific?
I need users (doctors/staff) to be isolated per clinic.


3. How can I make sure user login works correctly and is scoped to the right schema?


4. What's the best way to handle domain/subdomain routing for tenants (ex: clinic1.mycrm.com, clinic2.mycrm.com)?


5. Any example repo, best practices, or gotchas I should be aware of?



I’d love to get some feedback or code architecture examples from anyone who’s implemented a similar setup. My goal is to keep tenant data fully isolated and support a clean onboarding experience for new clinics.

Thanks a lot in advance!

How can I give out a webapp but not the source code?


I want to give someone a django app I made to use locally but I dont want them to be able to reproduce or make changes to the code. Whats a good way to do so?

Ive seen Obfuscation (pyarmor) and making Licens Keys is a good way to go but have no real knowledge of that process. Also saw Pyinstaller might be an option but again, no Idea. Any advice or usefull links are appreciated.

BONUS QUESTION: How can I make the install process fool proof for the user? Just as far as installing python and requirements goes along with the project in one install file.

PyPDFForm v3.0.0 has released

Hello r/Python! About a year ago I made a post about an open source project I have been working on for about 5 years called PyPDFForm. It is a Python library that specializes in PDF form manipulations, providing essential functionalities such as inspect/edit form fields, filling forms, creating form fields, and many more.

The project received some very positive feedback from the community and has been evolving since then. Right now it's at about 14k monthly pip installs and I'm constantly getting new issues opened for different requests for the library. And because of the rise of its usage there are some groundbreaking major changes needed to happen to the library in order to address some of its legacy problems.

So it is my pleasure to announce that, just this morning, PyPDFForm has released its v3.0.0 major update. I wrote a long paragraph explaining why V3 is necessary. But here I will highlight some of the key changes in it:

1. Complete native PDF form filling. This is the legacy issue that V3 fixes. Instead of what used to be a watermark based approach, now every PDF form filled using PyPDFForm will be the same as if being filled by hand.
2. Best compatibility with Adobe Acrobat you will

Best WebSocket Library

Hi everyone! I am developing an application that requires real-time data fetching from an API, for which I need to use the WebSocket protocol. As of June 2025, what is the best library to implement WebSockets in Python? As of now, the module that handles fetching data from the API isn't very complex — its only requirement is to be able to smoothly handle around 50-100 concurrent connections with the API, where the rate of data flow is about 10 bytes per second for each connection. While the per-connection data-flow rate is expected to remain at only 10 bytes, the number of open concurrent connections may grow up to 3000, or even more. Thus, scalability is a factor that I need to consider.

I searched this sub and other related subs for discussions related to the websockets library, but couldn't find any useful threads. As a matter of fact, I couldn't find a lot of threads specifically about this library. This was unexpected, because I assumed that websockets was a popular library for implementing WebSockets in Python, and based on this assumption, I further assumed that there would be a lot of discussions related to it on Reddit. Now I

docker-pybuild: Embed Dockerfiles directly in your Python scripts

Hey r/Python! I wanted to share a small proof-of-concept I created that lets you build Docker images directly from Python scripts with embedded Dockerfiles.

# What My Project Does

docker-pybuild is a Docker CLI plugin inspired by PEP-723 (which allows you to specify Python version and dependencies in script metadata). It extends this concept to include a complete Dockerfile in your Python script's metadata.

# Target Audience

It's pretty much just a proof-of-concept at this point, but I thought someone might find it handy.

# Comparison

I'm not really aware of any similar projects, but I'd be happy to hear if someone knows of any alternatives.

# Example

# /// script
# requires-python = ">=3.11"
# dependencies =
# "requests<3"
#
# tool.docker
# Dockerfile = """
# FROM python:3.11
# RUN pip install pipx
# WORKDIR /app
# COPY application.py /app
# ENTRYPOINT "pipx", "run", "/app/application.py"
# """
# ///
