AI doesn't work


The AI for Archicad 27 isn't functioning on my MacBook Pro M1. I'm encountering the following error message: RuntimeError: MPS backend out of memory (MPS allocated: 16.84 GB, other allocations: 1.30 GB, max allowed: 18.13 GB). Tried to allocate 10.00 MB on private pool. Use PYTORCH_MPS_HIGH_WATERMARK_RATIO=0.0 to disable upper limit for memory allocations (may cause system failure).

same error in windows 10


Same error, I tried on Windows and Mac 


Installed last Friday on my MacBook Pro M1 Max 64 GB Memory. Seemed to work fine initially, but now I get the attached error message. Any advice?


Not aware that I changed any base parameters, but could have by accident.

Do you remember making any manual changes on your JSON file, mentioned in the error message?

My GPU: memory:


From my reading, my laptop selects which GPU to use based on a performance level (Windows 11: System>Display>Graphics). I have tried changing the performance setting from 'Let Windows Decide' to high performance for ArchiCAD 27 and Python (from C:\sd.webui\system\python) but still get the same prompt./

Hi edseiber,


I remember you had this issue previously and wrote this: 

"My issue is now resolved. I discovered I had the JSON Config Template nested within the AI Visualizer folder under the Extras folder. Once I removed the JSON Config Template from the AI Visualizer folder and placed it directly in Extras, images generated fine"


Can you please check this again?


Have a Happy New Year!

Hi wilson0083,


Please note that the minimum system requirement to use the Add-on is: 8 GB of VRAM on Windows and 16 GB of RAM on Apple Silicon.
For the detailed requirements read the system requirements.
