Old method bug

Trying old method with default settings, got this error:

Something went wrong

@TheLastBen I can’t seem to get as good results as the old version.

1. Without the class images that I can upload myself, it seems that pets or art styles can’t seem to work as well. And when I put in more class images previously, it greatly improves the results too. (actually I’m not too sure what to enter for faces option for pets or art styles)
2. I can’t really understand how the text encoder works or how much to put in, but it seems to really affect how much I can stylize and well the results look. =(

Try with the new one, if you’re not getting good results, I’ll walk you through it.
