What's New in 2.3.5.post2
This is a bugfix release. In previous versions, the built-in updating script did not update the Xformers library when the torch library was upgraded, leaving people with a version that ran on CPU only. Install this version to fix the issue so that it doesn't happen when updating to future versions of InvokeAI 3.0.0.
As a bonus, this version allows you to apply a checkpoint VAE, such as vae-ft-mse-840000-ema-pruned.ckpt to a diffusers model, without worrying about finding the diffusers version of the VAE. From within the web Model Manager, choose the diffusers model you wish to change, press the edit button, and enter the Location of the VAE file of your choice. The field will now accept either a .ckpt file, or a diffusers directory.
Installation / Upgrading
To install 2.3.5.post2 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.
InvokeAI-installer-v2.3.5.post2.zip
If you are using the Xformers library, and running v2.3.5.post1 or earlier, please do not use the built-in updater to update, as it will not update xformers properly. Instead, either download the installer and ask it to overwrite the existing invokeai directory (your previously-installed models and settings will not be affected), or use the following recipe to perform a command-line install:
- Start the launcher script and select option # 8 - Developer's console.
- Give the following command:
pip install invokeai[xformers] --use-pep517 --upgrade
If you do not use Xformers, the built-in update option (# 9) will work, as will the above command without the "[xformers]" part. From v2.3.5.post2 onward, the updater script will work properly with Xformers installed.
Developers and power users can upgrade to the current version by activating the InvokeAI environment and then using:
pip install --use-pep517 --upgrade InvokeAI
You may specify a particular version by adding the version number to the command, as in:
pip install --use-pep517 --upgrade InvokeAI==2.3.5.post2
To upgrade to an xformers version if you are not currently using xformers, use:
pip install --use-pep517 --upgrade InvokeAI[xformers]
You can see which versions are available by going to The PyPI InvokeAI Project Page
Known Bugs in 2.3.5.post2
These are known bugs in the release.
- Windows Defender will sometimes raise Trojan or backdoor alerts for the
codeformer.pthface restoration model, as well as theCIDAS/clipsegandrunwayml/stable-diffusion-v1.5models. These are false positives and can be safely ignored. InvokeAI performs a malware scan on all models as they are loaded. For additional security, you should use safetensors models whenever they are available.
Getting Help
Please see the InvokeAI Issues Board or the InvokeAI Discord for assistance from the development team.
Development Roadmap
This is very likely to be the last release on the v2.3 source code branch. All new features are being added to the main branch. At the current time (mid-May, 2023), the main branch is only partially functional due to a complex transition to an architecture in which all operations are implemented via flexible and extensible pipelines of "nodes".
If you are looking for a stable version of InvokeAI, either use this release, install from the v2.3 source code branch, or use the pre-nodes tag from the main branch. Developers seeking to contribute to InvokeAI should use the head of the main branch. Please be sure to check out the dev-chat channel of the InvokeAI Discord, and the architecture documentation located at Contributing to come up to speed.
