# 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.

Disco:

Somnai (https://twitter.com/Somnai_dreams) added Diffusion Animation techniques, QoL improvements and various implementations of tech and techniques, mostly listed in the changelog below.

3D animation implementation added by Adam Letts (https://twitter.com/gandamu_ml) in collaboration with Somnai.

  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

---

`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

def get_inbetweens(key_frames, integer=False):
    """Given a dict with frame numbers as keys and a parameter value as values,
    return a pandas Series containing the value of the parameter at every frame from 0 to max_frames.
    Any values not provided in the input dict are calculated by linear interpolation between
    the values of the previous and next provided frames. If there is no previous provided frame, then
    the value is equal to the value of the next provided frame, or if there is no next provided frame,
    then the value is equal to the value of the previous provided frame. If no frames are provided,
    all frame values are NaN.

    Parameters
    ----------
    key_frames: dict
        A dict with integer frame numbers as keys and numerical values of a particular parameter as values.
    integer: Bool, optional
        If True, the values of the output series are converted to integers.
        Otherwise, the values are floats.
    
    Returns
    -------
    pd.Series
        A Series with length max_frames representing the parameter values for each frame.
