Hello, i am having trouble just installing it.  i have tried copy/paste the text from the Archicad download PDF, as well as from the Home Brew website (per a tip on YouTUBE @DavidTomic channel).

please see screenshot.  i open Terminal, copy/paste the text into the Terminal, and click "Return".  immediately gives the error "Illegal variable name." 

it did download the Command Line Developer Tools (i think, it downloaded something).

thank you

Hi CSverci,


Thanks for the picture.


Please try to launch the bash shell first in the Terminal:

Hit enter, then run the install command:
bash -c "$(curl -fsSL"


Kind regards,

At first it didn't work and got the results below.  So I tried doing all the steps again and it was the same results.  I extracted with winwar from download folder to C:/ folder.

I ran run.bat and runhighvram.bat and this is what i got: 




is this in the right place?

ok, partly got it working, but not really.  The PDF installation guide didn't say anything about needing to install Python, or was this supposed to be installed with the package?  So downloaded the latest. Now it's saying that it's incompatible:

So I downloaded 3.10.6 version and uninstalled 3.12.2.  and this is the result:

what's my next step?

Hi sknsnw9,


Thanks for the screenshots.


Python is not needed to run the Add-on. I suspect all of the errors are consequences of the issue shown in the first picture: the 'file ownership' error.

Please unzip the sd.webui folder directly to the C: root folder. Unzipping elsewhere and copying it to the C: root can fail.


Kind regards,

Thank you.  I did extract it twice directly to the C: root folder.  This time, I deleted it and restarted the computer.  Instead of using winrar extract, I dragged it directly to the C: folder.  For whatever reason that seems to work.  Just tested it out, it's now working!

Getting a runtime error with a M1 Pro Mac:

"    RuntimeError: MPS backend out of memory (MPS allocated: 16.62 GB, other allocations: 1.49 GB, max allowed: 18.13 GB). Tried to allocate 50.00 MB on private pool. Use PYTORCH_MPS_HIGH_WATERMARK_RATIO=0.0 to disable upper limit for memory allocations (may cause system failure)."

when trying not to run in High VRAM Mode I also get:

"    RuntimeError: "upsample_nearest2d_channels_last" not implemented for 'Half'

Hi kylevfa,


It seems that your device runs out of memory. Please close all other apps running in the background and start the engine in lowVRAM. Also using the Add-on right after the device startup can help and it is worth changing the generated picture size as well.
