P Learn diffusion models with Hugging Face course 🧨
Hi there, it's Lewis here from the open-source team at Hugging Face 👋
Since the release of Dalle-Mini and Stable Diffusion a few months ago, you may have seen your timelines filled with impressive text-generated images like the one below:
Image generated with textual inversion and Stable Diffusion
These images are generated by an exciting branch of research called diffusion models, which is rapidly being applied to generate novel structures in computer vision, audio, and even molecular biology 🤯!
To help the community get up to speed on this fast-moving field, we've joined forces with the awesome Jonathan Whitaker to launch a free course on all aspects of diffusion models 🔥
In this course, you will:
👩🎓 Study the theory behind diffusion models
🧨 Learn how to generate images and audio with the popular 🤗 Diffusers library
🏋️♂️ Train your own diffusion models from scratch
📻 Fine-tune existing diffusion models on new datasets
🗺 Explore conditional generation and guidance
🧑🔬 Create your own custom diffusion model pipelines
The course will be released in a few weeks and you can register via the signup form here: https://huggingface.us17.list-manage.com/subscribe?u=7f57e683fa28b51bfc493d048&id=ef963b4162
Looking forward to meeting you all in the course 🤗!

Updating a Django 1. project in production
Hi all, I’ve been using Django for a while now, but I now have the task at work of updating a production Django 1. project to Django 4. I’ve been able to fix the majority of the bugs, but the biggest hurdle is dealing with the database. This thing has a couple of models with millions of rows each and it was made before migrations were a thing in Django.
Do any of you have any experience in dealing with this type of thing with minimum downtime? How did you approach it?

Methods for dynamically loading test db data
I'm looking for a more efficient way to quickly and dynamically load data into sqlite (in memory) for my testing. I came across Flask-Fixtures but the project hasn't been updated in a few years and has several deprecation warnings for SQLAlchemy and Flask APIs.
I started writing my own `Loader` class which parses some JSON files into memory, but I'm fighting app context errors when using application factories.
Are there other libraries or frameworks which make loading test data easier that you use? Any tips would be great.

Ploomber Cloud - Parametrizing and running notebooks in the cloud in parallel
Hi r/IPython!
I want to share what we've been working on at Ploomber, and we're releasing today!
We started with an open-source framework to help data practitioners make their work reproducible. However, after months of building and learning from our community, we realized that many needed help with the setup: getting Python installed, getting dependencies, running experiments locally, etc.
So we decided to work on a complementary cloud product to solve these issues. Ploomber Cloud (there is a free tier!) allows you to parametrize a notebook and spins up parallel jobs without configuring infrastructure. It works like this:
1. Add a cell at the top of your notebook with the parameters you want
2. Submit the notebook from the command-line interface
3. We parse your notebook's content to get the packages you need and create a Docker image
4. We push the Docker image and spin instances to run your jobs in parallel (one per each parameter combination)
5. We upload the results to cloud storage so you can review them later
We've seen our community use it for a wide range of applications. Here are the most common use cases:
1. Fit computationally intensive models (e.g., Bayesian modeling, time series forecasting)
2. Tune hyperparameters (i.e., spin up 100 jobs to

Sending files from Flask to React Frontend
I am creating a reactjs (frontend) and flask server (Backend) and I am experiencing some issues with sending files from flask to react.
My application work this way:
1. On Page 1, I upload files from react js to flask (followed a tutorial on this) upon cllicking the 'upload' button
2. Clicking the 'upload' button will call a function from the flask server to process the file and the return value should be a pdf file.
3. Upon clicking to Page 2, the processed file will then displayed on my pdf viewer on page 2. So I would require the returned file from function called in Page 1 to be viewed when i click Next page to Page 2, the pdf viewer.
However, I am having troubles with the flow. I am now sure how I can return a file in the function in flask on the upload function called in page 1, which will be shown on my frontend only when I click to page 2. I have been very unsuccessful at all my attempts...
I tried to redirect to another function which returns a send_file function to a different app route but this does not work at all. I have also looked at

Flask App works on development server but not on IIS running on 2008r2
I have a flask app that runs some API calls to a meraki cloud environment. The app runs perfectly using flasks built in development server on the 2008 r2 server. I have the server running using IIS and fastcgi.
The site will come up via my URL and the site looks like it works. As soon as I click the button to trigger the api calls in the app I immediately get “Internal Server Error, The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.” I am confused because the flask app runs the api calls fine on the same machine, in the same folder location using flasks built in server but not using IIS. Which leads me to believe the code works. The IIS logs I know of do not show any more info. I am thinking I must have missed something for deployment. I have already thought of trying a different hosting method but I need to use this specific machine and I need ad integrated authentication which is very easy in IIS, it seems there isn’t many options.
Anyone experience something

Run waitress in background on windows server.
Can someone point me in the right direction to run waitress without a console on a windows server?
This project is for a manufacturing production environment. The server is on the network of application that is calling the HTTP request so there is no security concerns. Currently I'm running waitress-serve from the command line to get the flask application to work. I'm able to send request and get data, which I'm very excited about getting this far, but now I want to run it without the console and without me being logged in. What is the best way to do this?
Thanks.

Help! Can't get Flask to detect packages
Hi, bit of a newbie here, trying to get my first Flask project up and running. I've got hello world down, now I've written a small project, which uses a couple of packages like dateutil and pytz. I got the packages installed in a virtual environment, and if I write a non-Flask script it runs just fine.
But if I try and do flask run then I get for example
ModuleNotFoundError: No module named 'pytz'
It's almost like flask isn't running in the venv or something? Does anyone know what I've done wrong and how to fix it?
A super-quick example:
hello.py:
from flask import Flask
import pytz
print(pytz.timezone('UTC')) #stupid but just to show things work
app = Flask(__name__)
@app.route("/")
def hello_world():
return "<p>Hello, World!</p>"
Then I run:
venv\Scripts\activate
python hello.py
#prints "UTC" as expected
set FLASK_APP=hello
set FLASK_ENV=development
flask run
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.

Do you follow the official DRF layout?
Maybe a weird question as I most likely should follow the official documentation, but I have made already one simple project following Django's standard layout where every app sits alongside <yourprojectname> directory containing urls.py, seetings.py etc. instead of being installed inside that <yourprojectname> directory as recommended by the official DRF quickstart guide and I didn't came across any problem. So what's the standard?

Opinion needed: react or vue as front end framework with Django?
Hi,
I'm thinking about using either react or vue as a front end framework. I'm just wanting to know peoples opinion about using either with Django or any experience they've had with it. Also do you use the client-side routing that is available in both frameworks? What's the advantage of using a front end framework over just straight HTML/CSS with bootstrap? Thanks

Confused about 400 Bad Request for POST endpoint
Hello
I am trying to process a simple POST request on my Flask server.
flaskapp.py :
from flask import Flask, request
app = Flask(name)
@app.route("/")
def hello():
return "Welcome to Flask Application!"
@app.route('/webhook', methods='POST')
def webhook():
if request.method == 'POST':
print("Data received from Webhook is: ", request.json)
return "Webhook received!"
if name == "main":
app.run(host='0.0.0.0')
My root endpoint works fine as shown in the screenshot below, but my POST endpoint is returning a 400 Bad Request. This is confusing to me since it seems like it's all been formatted correctly. Does anyone see an obvious issue here? thanks.

I am currently working on my first website, and using/learning Django had been a fantastic experience. I am stepping up my game and working on intergrating Stripe to sell services on my website, and I am struggling using such a complex API.
