The same question with @z0yuu , where can we download the extra alpha mask to reproduce the model ? Thanks.

We have make alpha by ourselves, but we can't get similar result. If possible, please give some advise.

you could run scripts/prepare_matting_dataset.py before scripts/prepare_seg_tri_dataset.py. prepare_matting_dataset.py will generate a pesudo alpha mask by gaussian blur
