[coffeedrinker0725]

faceswaplab 1.2.7 is ok when running on stable difussion webui (A1111). However, running on stable difussion webui forge, it is different: in case of txt2img, it ok. but in case of img2imge, it struck attribute error: FaceSwapLab - ERROR - Failed to swap face in postprocess method : 'tuple' object has no attribute 'save'. How can this be corrected?
