Convert original Stable Diffusion checkpoints and safetensors to diffusers

Stable Diffusion model conversion script

Convert from the 'original implementation' to Huggingface diffusers. Both .safetensors and .ckpt checkpoints are supported.

The script is adapted from the diffusers conversion script: https://github.com/huggingface/diffusers/blob/main/scripts/convert_original_stable_diffusion_to_diffusers.py

Usage:

python enhanced_convert_original_stable_diffusion_to_diffusers.py --checkpoint_path "<input_model_filepath>" --dump_path "<output_directory_path>" --extract_ema

For inference use, extracting with --extract_ema is usually recommended. This will be ignored if the source model does not contain both EMA and non-EMA weights.

Everything I understand about chatgpt

ChatGPT Resources

Context

ChatGPT appeared like an explosion on all my social media timelines in early December 2022. While I keep up with machine learning as an industry, I wasn't focused so much on this particular corner, and all the screenshots seemed like they came out of nowhere. What was this model? How did the chat prompting work? What was the context of OpenAI doing this work and collecting my prompts for training data?

I decided to do a quick investigation. Here's all the information I've found so far. I'm aggregating and synthesizing it as I go, so it's currently changing pretty frequently.

The text version of my GStreamer talk at sunhacks 2020

Introduction

Hi everyone! Today I'm going to be giving you a crash course in video processing using Python. Coming out of this talk, you'll be able to take video from pretty much any source, decode it, apply visual effects, and display it on-screen. To do this, we're going to be using a library named GStreamer, an incredibly powerful and versatile framework. This is the same tool that the pros use, but don't feel intimidated! GStreamer actually makes it very easy to do impressive things with video and you'll be well on your way to making something great in just the time it takes to watch this talk.

If you fall behind at any point during the live presentation, don't worry! I have a text version of this talk available with the same content and more. There should be a link in the description.

Installing Dependencies

Let's start by installing everything we'll need to start using GStreamer in Python. This is probably the hardest part, so if you managed to do it before this talk, it's all smooth sailing fro

Beginner Friendly: Using Multiple SSH keys

How to follow this guide

The problem

I have one computer and two different github accounts. One is for work, the other is for my personal stuff. I can't use the same ssh key twice, so I have to use different ssh key for each of my accounts. How do I do that? How do I switch between these ssh keys?
