Installation

This fork is supported across multiple platforms. You can find individual installation instructions below.

• Linux

• Windows

• Macintosh

Hardware Requirements

System

You wil need one of the following:

• An NVIDIA-based graphics card with 4 GB or more VRAM memory.
• An Apple computer with an M1 chip.

Memory

• At least 12 GB Main Memory RAM.

Disk

• At least 6 GB of free disk space for the machine learning model, Python, and all its dependencies.

Note

Precision is auto configured based on the device. If however you encounter errors like 'expected type Float but found Half' or 'not implemented for Half' you can try starting dream.py with the --precision=float32 flag:

(ldm) ~/stable-diffusion$ python scripts/dream.py --precision=float32

Latest Changes

• vNEXT (TODO 2022)

  • Deprecated --full_precision / -F. Simply omit it and dream.py will auto configure. To switch away from auto use the new flag like --precision=float32.

• v1.14 (11 September 2022)

  • Memory optimizations for small-RAM cards. 512x512 now possible on 4 GB GPUs.
  • Full support for Apple hardware with M1 or M2 chips.
  • Add "seamless mode" for circular tiling of image. Generates beautiful effects. (prixt).
  • Inpainting support.
  • Improved web server GUI.
  • Lots of code and documentation cleanups.

• v1.13 (3 September 2022

  • Support image variations (see VARIATIONS (Kevin Gibbons and many contributors and reviewers)
  • Supports a Google Colab notebook for a standalone server running on Google hardware Arturo Mendivil
  • WebUI supports GFPGAN/ESRGAN facial reconstruction and upscaling Kevin Gibbons
  • WebUI supports incremental display of in-progress images during generation Kevin Gibbons
  • A new configuration file scheme that allows new models (including upcoming stable-diffusion-v1.5) to be added without altering the code. (David Wager)
  • Can specify --grid on dream.py command line as the default.
  • Miscellaneous internal bug and stability fixes.
  • Works on M1 Apple hardware.
  • Multiple bug fixes.
