Installation / Upgrading

Installing using the InvokeAI zip file installer

To install 3.0.2 please download the zip file at the bottom of the release notes (under “Assets”), unpack it, and then double-click to launch the script install.sh (Macintosh, Linux) or install.bat (Windows). Alternatively, you can open a command-line window and execute the installation script directly. If you have an earlier version of InvokeAI installed, we recommend that you install into a new directory, such as invokeai-3 instead of the previously-used invokeai directory. We provide a script that will let you migrate your old models and settings into the new directory, described below.

In the event of an aborted install that has left the invokeai directory unusable, you may be able to recover it by asking the installer to install on top of the existing directory. This is a non-destructive operation that will not affect existing models or images.

Upgrading in place

All users can upgrade from 3.0.1 using the launcher’s “upgrade” facility. If you are on a Linux or Macintosh, you may also upgrade a 2.3.2 or higher version of InvokeAI to 3.0.2 using this recipe, but upgrading from 2.3 will not work on Windows due to a 2.3.5 bug (see workaround below):

  1. Enter the root directory you wish to upgrade
  2. Launch invoke.sh or invoke.bat
  3. Select the upgrade menu option [9]
  4. Select “Manually enter the tag name for the version you wish to update to” option [3]
  5. Select option [1] to upgrade to the latest version.
  6. When the upgrade is complete, the main menu will reappear. Choose “rerun the configure script to fix a broken install” option [7]

Windows users can instead follow this recipe:

  1. Enter the 2.3 root directory you wish to upgrade
  2. Launch invoke.sh or invoke.bat
  3. Select the “Developer’s console” option [8]
  4. Type the following commands:
pip install "invokeai @ https://github.com/invoke-ai/InvokeAI/archive/refs/tags/v3.0.2.zip" --use-pep517 --upgrade
invokeai-configure --root .

This will produce a working 3.0 directory. You may now launch the WebUI in the usual way, by selecting option [1] from the launcher script

After you have confirmed everything is working, you may remove the following backup directories and files:

  • invokeai.init.orig
  • models.orig
  • configs/models.yaml.orig
  • embeddings
  • loras

To get back to a working 2.3 directory, rename all the ‘*.orig” files and directories to their original names (without the .orig), run the update script again, and select [1] “Update to the latest official release”.

Note:

  • If you had issues with inpainting on a previous InvokeAI 3.0 version, delete your models/ .cache folder before proceeding.

What to do if problems occur during the install

Due to the large number of Python libraries that InvokeAI requires, as well as the large size of the newer SDXL models, you may experience glitches during the install process. This particularly affects Windows users. Please see the Installation Troubleshooting Guide for solutions.

In the event that an update makes your environment unusable, you may use the zip installer to reinstall on top of your existing root directory. Models and generated images already in the directory will not be affected.

Migrating models and settings from a 2.3 InvokeAI root directory to a 3.0 directory

We provide a script, invokeai-migrate3, which will copy your models and settings from a 2.3-format root directory to a new 3.0 directory. To run it, execute the launcher and select option [8] “Developer’s console”. This will take you to a new command line interface. On the command line, type:

invokeai-migrate3 --from <path to 2.3 directory> --to <path to 3.0 directory>

Provide the old and new directory names with the --from and --to arguments respectively. This will migrate your models as well as the settings inside invokeai.init. You may provide the same --from and --to directories in order ot upgrade a 2.3 root directory in place. (The original models and configuration files will be backed up.)

Upgrading using pip

Developers and power users can upgrade to the current version by activating the InvokeAI environment and then using:

pip install --use-pep517 --upgrade InvokeAI
invokeai-configure --yes --skip-sd-weights

You may specify a particular version by adding the version number to the command, as in:

pip install --use-pep517 --upgrade  InvokeAI==3.0.2
invokeai-configure --yes --skip-sd-weights

Important: After doing the pip install, it is necessary to invokeai-configure in order to download new core models needed to load and convert Stable Diffusion XL .safetensors files. The web server will refuse to start if you do not do so.

Getting Started with SDXL

Stable Diffusion XL (SDXL) is the latest generation of StabilityAI’s image generation models, capable of producing high quality 1024x1024 photorealistic images as well as many other visual styles. SDXL comes with two models, a “base” model that generates the initial image, and a “refiner” model that takes the initial image and improves on it in an img2img manner. In many cases, just the base model will give satisfactory results.

To download the base and refiner SDXL models, you have several options:

  1. Select option [5] from the invoke.bat launcher script, and select the base model, and optionally the refiner, from the checkbox list of “starter” models.
  2. Use the Web’s Model Manager to select “Import Models” and when prompted provide the HuggingFace repo_ids for the two models:
    • stabilityai/stable-diffusion-xl-base-1.0
    • stabilityai/stable-diffusion-xl-refiner-1.0
  3. Download the models manually and cut and paste their paths into the Location field in “Import Models”

Also be aware that SDXL requires at 6-8 GB of VRAM in order to render 1024x1024 images and a minimum of 16 GB of RAM. For best performance, we recommend the following settings in invokeai.yaml:

precision: float16
max_cache_size: 12.0
max_vram_cache_size: 0.5

Known Issues in 3.0

This is a list of known bugs in 3.0.2rc1 as well as features that are planned for inclusion in later releases:

  • Variant generation was not fully functional and did not make it into the release. It will be added in the next point release.
  • Perlin noise and symmetrical tiling were not widely used and have been removed from the feature set.
  • High res optimization has been removed from the basic user interface as we experiment with better ways to achieve good results with nodes. However, you will find several community-contributed high-res optimization pipelines in the Community Nodes Discord channel at https://discord.com/channels/1020123559063990373/1130291608097661000 for use with the experimental Node Editor.
