We know that taking part in an experiment can be challenging from time to time. Do you have issues with installing or running the Archicad AI Visualizer Add-on? This is your place to ask your questions and initiate discussion with others about technical difficulties you may experience while trying to install or run the experimental add-on, or generate images.

I noticed that a complex model can cause the engine to fail. The simpler the model, the more chance on a successful render. 

Windows 11 File Explorer supports unzipping ZIP files by default. If you could not unzip it with the default solution, please contact our support for further help.

AI engine has problem with files ownership. It happens when you copy files under one user and try to use them with another user logged into OS. Running AC as admin helps but when you don't have this option (your admin don't want to give you his password 😉 ) copy files to C: when logged as user that will use AI engine. It helped with this error.


Base on the information provided it seems a step was likely missing during the installation, somewhere.

Can you please confirm whether you followed each step in the instructions, in the given order?

If you are not sure, please repeat the steps again following the guide.


If you followed the guide with the provided issue still appearing, please contact support, for the most efficient solution.

Could you please make a screenshot of the same dialog, but changing its width so that the full location path is visible?

Also, please share which Archicad version + build number are you trying to run it. Is it perhaps Start Edition?

Hi All.

All the addon + Terminal install has been successful but getting this error message and the below message in the terminal box :


File "/opt/homebrew/lib/python3.10/site-packages/torch/nn/", line 3931, in interpolate

        return torch._C._nn.upsample_nearest2d(input, output_size, scale_factors)

    RuntimeError: "upsample_nearest2d_channels_last" not implemented for 'Half'


Having run Stable Diffusion before I am wondering if this is something that needs adding in the webui-user file ?

I am on a Apple M1 Max FYI
