InvokeAI/source_installer/install.sh

#!/bin/bash

# This script will install git and conda (if not found on the PATH variable)
#  using micromamba (an 8mb static-linked single-file binary, conda replacement).
# For users who already have git and conda, this step will be skipped.

# Next, it'll checkout the project's git repo, if necessary.
# Finally, it'll create the conda environment and preload the models.

# This enables a user to install this project without manually installing conda and git.
