hi
i trained on company dataset for almost 3-4 days on GTX 1080TI. Please see the log file. Error was keep getting low as expected but when i tested even on trained images. It is behaving strangely
log.txt

Please see the orignal image and result after training. Expect for a few white dashes nothing is there.

Any idea what i did wrong here. Note i generated alphas by seprating the alpha channel in provided masks and not KNN. Sample orignal GT is

if you don't have ground truth alpha matte, you need to generate. The mask is just a coarse seg of the person ,can not represent the ground truth alpha matte .you need to use the mask to generate the trimap ,then use trimap and origin image as the input of knn-matting to generate alpha matte.We use the alpha matte that knn-matting generate as the approximation of ground truth alpha matte.
