# Disco Diffusion v5.1 - Now with Turbo
In case of confusion, Disco is the name of this notebook edit. The diffusion model in use is Katherine Crowson's fine-tuned 512x512 model
For issues, join the [Disco Diffusion Discord](https://discord.gg/msEZBy4HxA) or message us on twitter at [@somnai_dreams](https://twitter.com/somnai_dreams) or [@gandamu](https://twitter.com/gandamu_ml)

#### Credits
Original notebook by Katherine Crowson (https://github.com/crowsonkb, https://twitter.com/RiversHaveWings). It uses either OpenAI's 256x256 unconditional ImageNet or Katherine Crowson's fine-tuned 512x512 diffusion model (https://github.com/openai/guided-diffusion), together with CLIP (https://github.com/openai/CLIP) to connect text prompts with images.
Modified by Daniel Russell (https://github.com/russelldc, https://twitter.com/danielrussruss) to include (hopefully) optimal params for quick generations in 15-100 timesteps rather than 1000, as well as more robust augmentations.
Further improvements from Dango233 and nsheppard helped improve the quality of diffusion in general, and especially so for shorter runs like this notebook aims to achieve.
Vark added code to load in multiple Clip models at once, which all prompts are evaluated against, which may greatly improve accuracy.
The latest zoom, pan, rotation, and keyframes features were taken from Chigozie Nri's VQGAN Zoom Notebook (https://github.com/chigozienri, https://twitter.com/chigozienri)
Advanced DangoCutn Cutout method is also from Dango223.

v1 Update: Oct 29th 2021 - Somnai
QoL improvements added by Somnai (@somnai_dreams), including user friendly UI, settings+prompt saving and improved google drive folder organization.
v1.1 Update: Nov 13th 2021 - Somnai
Now includes sizing options, intermediate saves and fixed image prompts and perlin inits. unexposed batch option since it doesn't work
v2 Update: Nov 22nd 2021 - Somnai
Initial addition of Katherine Crowson's Secondary Model Method (https://colab.research.google.com/drive/1mpkrhOjoyzPeSWy2r7T8EYRaU7amYOOi#scrollTo=X5gODNAMEUCR)
Noticed settings were saving with the wrong name so corrected it. Let me know if you preferred the old scheme.
v3 Update: Dec 24th 2021 - Somnai
Implemented Dango's advanced cutout method
Added SLIP models, thanks to NeuralDivergent
Fixed issue with NaNs resulting in black images, with massive help and testing from @Softology
Perlin now changes properly within batches (not sure where this perlin_regen code came from originally, but thank you)
v4 Update: Jan 2021 - Somnai
Implemented Diffusion Zooming
Added Chigozie keyframing
Made a bunch of edits to processes
v4.1 Update: Jan 14th 2021 - Somnai
Added video input mode
Added license that somehow went missing
Added improved prompt keyframing, fixed image_prompts and multiple prompts
Improved UI
Significant under the hood cleanup and improvement
Refined defaults for each mode
Added latent-diffusion SuperRes for sharpening
Added resume run mode
v4.9 Update: Feb 5th 2022 - gandamu / Adam Letts
Added 3D
Added brightness corrections to prevent animation from steadily going dark over time
v4.91 Update: Feb 19th 2022 - gandamu / Adam Letts
Cleaned up 3D implementation and made associated args accessible via Colab UI elements
v4.92 Update: Feb 20th 2022 - gandamu / Adam Letts
Separated transform code
v5.01 Update: Mar 10th 2022 - gandamu / Adam Letts
IPython magic commands replaced by Python code
v5.1 Update: Mar 30th 2022 - zippy / Chris Allen and gandamu / Adam Letts
Integrated Turbo+Smooth features from Disco Diffusion Turbo -- just the implementation, without its defaults.
Implemented resume of turbo animations in such a way that it's now possible to resume from different batch folders and batch numbers.
3D rotation parameter units are now degrees (rather than radians)
Corrected name collision in sampling_mode (now diffusion_sampling_mode for plms/ddim, and sampling_mode for 3D transform sampling)
Added video_init_seed_continuity option to make init video animations more continuous
v5.1 Update: Apr 4th 2022 - MSFTserver aka HostsServer
Removed pytorch3d from needing to be compiled with a lite version specifically made for Disco Diffusion
Remove Super Resolution
Remove SLIP Models
Update for crossplatform support

**Diffusion settings (Defaults are heavily outdated)**
---
This section is outdated as of v2
Setting | Description | Default
--- | --- | ---
**Your vision:**
`text_prompts` | A description of what you'd like the machine to generate. Think of it like writing the caption below your image on a website. | N/A
`image_prompts` | Think of these images more as a description of their contents. | N/A
**Image quality:**
`clip_guidance_scale` | Controls how much the image should look like the prompt. | 1000
`tv_scale` | Controls the smoothness of the final output. | 150
`range_scale` | Controls how far out of range RGB values are allowed to be. | 150
`sat_scale` | Controls how much saturation is allowed. From nshepperd's JAX notebook. | 0
`cutn` | Controls how many crops to take from the image. | 16
`cutn_batches` | Accumulate CLIP gradient from multiple batches of cuts | 2
**Init settings:**
`init_image` | URL or local path | None
`init_scale` | This enhances the effect of the init image, a good value is 1000 | 0
`skip_steps Controls the starting point along the diffusion timesteps | 0
`perlin_init` | Option to start with random perlin noise | False
`perlin_mode` | ('gray', 'color') | 'mixed'
**Advanced:**
`skip_augs` |Controls whether to skip torchvision augmentations | False
`randomize_class` |Controls whether the imagenet class is randomly changed each iteration | True
`clip_denoised` |Determines whether CLIP discriminates a noisy or denoised image | False
`clamp_grad` |Experimental: Using adaptive clip grad in the cond_fn | True
`seed` | Choose a random seed and print it at end of run for reproduction | random_seed
`fuzzy_prompt` | Controls whether to add multiple noisy prompts to the prompt losses | False
`rand_mag` |Controls the magnitude of the random noise | 0.1
`eta` | DDIM hyperparameter | 0.5
..
**Model settings**
---
Setting | Description | Default
--- | --- | ---
**Diffusion:**
`timestep_respacing` | Modify this value to decrease the number of timesteps. | ddim100
`diffusion_steps` || 1000
**Diffusion:**
`clip_models` | Models of CLIP to load. Typically the more, the better but they all come at a hefty VRAM cost. | ViT-B/32, ViT-B/16, RN50x4

Parameters
----------
string: string

Raises
------
