What happened?

This issue arises when using the high res optimization to generate an image. It successfully makes both passes on the low res and higher res versions of the image, and at the end an error is printed to the console NameError: name 'gc' is not defined and does not reveal the finished image.

The issue was fixed by #1939 last week. Try to update your InvokeAI.

Alternatively, you can also fix it without updating InvokeAI by adding import gc statement into txt2img2img.py file at your InvokeAI installation. The file is located at (based on your stack trace log): C:\Users\artis\Documents\invokeai\.venv\lib\site-packages\ldm\invoke\generator\txt2img2img.py . You can insert import gc among import statements in the beginning of txt2img2img.py file.
