[Discussion] PyTorch favors Intel against AMD's rising?

PyTorch packages (both pypi and conda packages) require the Intel MKL library. As you know, Intel MKL uses a slow code path on non-Intel CPUs such as AMD CPUs. There was the MKL\_DEBUG\_CPU\_TYPE=5 workaround to make Intel MKL use a faster code path on AMD CPUs, but it has been disabled since Intel MKL version 2020.1.

PyTorch relies on Intel MKL for BLAS and other features such as FFT computation. Because pypi and conda packages require Intel MKL, the only solution is to build PyTorch from source with a different BLAS library. However, it looks like this isn't really pain-free (e.g. see [https://github.com/pytorch/pytorch/issues/32407](https://github.com/pytorch/pytorch/issues/32407)).

Moreover, if you look at issues like [https://github.com/pytorch/pytorch/issues/37746](https://github.com/pytorch/pytorch/issues/37746) or [https://github.com/pytorch/pytorch/issues/38412](https://github.com/pytorch/pytorch/issues/38412), it seems like they basically don't care about this problem.

Since PyTorch packages are slow by default on AMD CPUs and building PyTorch from source with a different BLAS library is also problematic, it seems like PyTorch is effectively protecting Intel CPUs from the "ryzing" of AMD's CPUs.

What do you think about this?

I finally finished and deployed my own URL shortener

It's been a long learning journey (for me at least), and I am so proud to present to you all this project. It is a custom URL shortener with no ads and not even having to wait before being redirected. Hope you all can use it rather than using the ones that show a 5 sec ad every time. I am hoping to keep the project deployed as long as I can, so please consider donating.

Explanation and everything else: [https://github.com/xemeds/tiny0](https://github.com/xemeds/tiny0)

Deployed version: [https://tiny0.cc/](https://tiny0.cc/)

EDIT: I apologize for it being slow to those in the continent of America, the server is hosted it Frankfurt, Germany.

Load CSVs or store in DB?

Hi all! I’m working on a small saas using flask with python. I’m importing a couple of CSVs that I use as bases to merge with user uploaded files. The files are small, around 50 to 10,000 observations in each.

My question: is it fine to leave them as CSVs that get loaded directly in the app as dataframes, or should I store them in a DB? Is there an advantage to one decision (like memory?)? Is there a best practice like for file sizes? (I.e. if my flat CSV files are ~1000 rows and not changing).

Thanks in advance— any input is appreciated!

Just released Starshot, a space rogue-like made completely in pygame!

I've just finished development on my game, and developed it completely in pygame! I found pygame easy to get started with but harder to develop more advanced features on, and would love to answer any questions people have about it. Some of the programming challenges included integration into steam (achievements, overlay etc.), developing enemy AI, randomising the level layouts/enemies and testing.

Elastic Beanstalk with Celery and SQS

I am trying to set up Celery and SQS on Elastic Beanstalk Linux2 Python 3.7.

I got some error when I was deploying my app to EB. The error was "ImportError: The curl client requires the pycurl library.". I already included pycurl==[7.43.0.5](https://7.43.0.5) in my requirements.txt. I also have "yum:libcurl-devel: \[\]" in my config file. I have tried for many hours and still can't figure out how to fix it. Did anyone successfully configure SQS and Celery on EB Linux2 Python 3.7?

Matplotlib Scatterplots, but with Emojis as Markers

I wrote a function to create scatterplots using emojis as markers to support some analysis & visualization I'm doing for a (very silly) side project. After a good bit of research (I was pretty shocked this didn't exist already), I built this based on [this article](https://towardsdatascience.com/how-i-got-matplotlib-to-plot-apple-color-emojis-c983767b39e0), but adapted to produce a scatterplot instead of a bar chart.

#Set the backend to use mplcairo
import matplotlib, mplcairo
print('Default backend: ' + matplotlib.get_backend())
matplotlib.use("module://mplcairo.macosx")

# IMPORTANT: Import these libraries only AFTER setting the backend

Passing variable from form into url

I have a flask app which provides certain information based on a public key. It also allows editing of the information for those with the matching private key.

@main.route('/thing/<unique_key>/')
@main.route('/thing/<unique_key>/secret/<secret_key>')
def view_thing(unique_key, secret_key = None):
if secret_key == None:
# render public information page through jinja

if secret_key == the_right_secret_key_I_pull_from_the_database:
# render private information page allowing editing through jinja

These routes all work fine and as expected.

I would like to include a form on the public information page which allows users with a private key to enter it and redirect to the private page (eg "Are you the owner of this information? Enter your private key and click submit to edit")

I know how I can pass the contents of a form to a flask POST method, but I don't want to do that here. How do I get it to instead take the input of the text box and redirect to the

[Beginner] Request for Django workflow suggestions

Hi all,

I'm currently learning Django and programming in general. I've managed to build a website, deploy it to a linux server, and use GCP for my static files. However, I'm not satisfied with my workflow.

I pushed to PROD using scp via the CLI. Then I continued to develop directly in PROD. This feels like a very bad way to continue.

How do development and deployment using GIT work in the context of webdev and Django? Develop locally, push to GIT and clone after logging on the server via ssh? Or do people use Docker to deploy to linux servers?

I would appreciate your advice and tips on how I can learn best-practices from the start. Thanks.
