One file, 181 MB, MIT licensed: BiRefNet-lite's own weights exported with ONNX's built-in DeformConv layer, which needs about 4 GB of memory per cut-out where rembg's copy of the same model needed 9.5 GB. Saved where rembg looks (`~/.u2net`, or `$U2NET_HOME`) and checked against its SHA-256 before it is kept. A machine that already has rembg's copy (224 MB) keeps working with it; `--check` reports it as not installed, so Setup & Status offers the lighter file. Installing the lighter file removes the older copy once the new one loads, and running this again removes a leftover one. Nothing is fetched without an explicit yes: AGENTS.md forbids weight downloads the user has not chosen. ) annotationsN)Path)mattereturnstrcdtjdz ddtjdtjtj}tjtj}|r|dtjdz dd|z }|S)Nz#Background remover: BiRefNet-lite (.A.0fz MB, MIT) from z to z, then removes the older copy it replaces (z MB) )r LEAN_BYTESLEAN_URL model_file LEAN_MODEL LITE_MODELis_file LITE_BYTES)textolders *G:\AssetFurnace\scripts\bootstrap_matte.py announcementr%s =%2BS2H Y = = = =()9:: = =D  U- . .E }}( 'AQTWAWa''$'' ( KNonec|tj}|r&td|dtjdz dddSdS)Nz! removed the older remover file z (r r z MB))rretire_older_copyprintr)removeds rrr0sY%''G_ ]']]U=MPS=S]]]]^^^^^__rpathrctj}|d5tfddD]}|| dddn #1swxYwY|S)Nrbc.dS)N)read)handlesrzsha256_of..9s&++g"6"6rr)hashlibsha256openiterupdate hexdigest)rdigestblockr#s @r sha256_ofr-6s ^  F 4!F6666<< ! !E MM%  !!!!!!!!!!!!!!!!     s,A##A'*A'target Path | Nonec:|ptjtj}|rdS|pt d}t dtjdz ddd||t d |tdS) zBiRefNet-lite, unless it is already there.
