ERROR: python3-venv is not installed, aborting


After dragging it to the Terminal window and hit Enter, this message shows up in HomeBrew / Terminal.


I have moved the AI Visualizer folder from Add-ons into Archicad 27 folder > Add-ons > Extra.

And i have moved the sd.webui folder into Archicad 27 folder.

I found a possible solution: 


after the installing process you must edit the file "" replacing the line: 



# python3 executable



with this one:



# python3 executable



Also it's necessary to configure the memory limit editing the ""  in this way:



export PARENT_SCRIPT="run"

# Directory containing

# Define the path to the script.

SCRIPT_DIR=$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )

# Check if the script exists.
if [ -f "$webui_directory/$WEBUI_SCRIPT" ]
# Change CWD to the webui_directory if exist else exit.
cd "$webui_directory" || exit 1

# Set the PYTORCH_MPS_HIGH_WATERMARK_RATIO environment variable

# Start the script with the specified parameters.
./"$WEBUI_SCRIPT" --no-half

echo "Error: not found in the '$webui_directory' subfolder."
exit 1



I'm copying the files, and you can test this solution; it's not optimal as this AI solver works mainly with the CPU if you don't have an NVIDIA GPU. Hopefully, with newer Metal SD versions, they are going to give us better Intel MAC versions (actually ComfyUI works with Metal). Use this fixed version with 512x512 pixels as larger resolutions give errors because of Lack of Memory issues.


Replace from /sd.webui directory and also replace from //sd.webui/webui directory

Dear Norbert Kucsma


Today, I just enabled some fixes for IntelMAC-based computers, basically editing some parameters inside the following files: and, and I have some results, as you can see in the attached images.


I'm also attaching the modified files if you want to take a look at them.


All the best

I have tried your idea of fixing the Intel Problem but sadly it didnt work. Maybe you have another solution or an idea if i did something wrong?

Hi Fegoalbe,


We are happy to see that the AI ​​Visualizer has stimulated the imagination of our interested parties in all areas, and attempts are being made that go beyond the limits of the official release. At the same time, we would like to emphasize that we recommend using the current version of AI Visualizer only in an environment that meets the official hardware requirements.


Feel free to keep experimenting, but we do not troubleshoot custom installations.


Kind regards,

Norbert Kucsma
