Third-party notices

Anuvani-Diarization's code is licensed under MIT OR Apache-2.0 (LICENSE-MIT, LICENSE-APACHE). It contains, ports or links work by others, listed here with their licences. The model weights have their own licences, set by the models they derive from (see the model card): the segmentation network is a fine-tuned derivative of BUT-FIT/diarizen-wavlm-large-s80-md-v2 and is CC BY-NC 4.0 (non-commercial); the PLDA model (BUT Speech@FIT) and the speaker-embedding network (pyannote/wespeaker-voxceleb-resnet34-LM) are CC BY 4.0.

Upstream Licence Where Licence text
DiariZen (BUT Speech@FIT), commit 844f555 MIT the segmentation network's code, verbatim (python/anuvani_diar/nn/seg/; also the frozen release's hf_port_poc/anuvani_diar_net/); its VBx and clustering set-up, ported to Rust (crates/diar-core) LICENSES/third_party/DiariZen-MIT.txt

Native libraries bundled in the wheel

Copied unchanged from the numpy 1.26.4 and soundfile 0.14.0 wheels, each checked by sha256 when it loads; their licence texts are in the wheel (anuvani_diar/_libs/LICENSES/, index in its README.txt):

Library Licence
OpenBLAS 0.3.23.dev (numpy 1.26.4's build) BSD-3-Clause
libgfortran 5 GPL-3.0 with the GCC Runtime Library Exception 3.1
libquadmath 0 LGPL-2.1-or-later
libsndfile 1.2.2, with FLAC 1.4.3, Ogg 1.3, Vorbis 1.3.7, Opus 1.4, mpg123 1.32.3, LAME 3.100 LGPL-2.1-or-later (libsndfile, mpg123, LAME); BSD-3-Clause (FLAC, Ogg, Vorbis, Opus)

libsndfile is LGPL: ANUVANI_DIAR_SNDFILE (with ANUVANI_DIAR_SNDFILE_UNCHECKED=1) runs the engine with another build of it (docs/WHEEL.md). The source of the LGPL libraries (libsndfile with its codecs and the script that built it; libquadmath, as the GCC source package it was built from) is in the model repository's third_party_sources/, whose README traces each binary to its source.

Container images the serving kit builds

triton_inference/ builds two images on the user's machine; they are not distributed here. The Triton image starts from nvcr.io/nvidia/tritonserver:24.10-py3 (NVIDIA Deep Learning Container License) and installs PyTorch and torchaudio 2.1.1 (BSD-3-Clause and BSD-2-Clause) and NVIDIA's cuBLAS and NVRTC wheels (NVIDIA proprietary licence); the service image starts from ubuntu:22.04 and installs FastAPI and Pydantic (MIT), Starlette and Uvicorn (BSD-3-Clause) and python-multipart (Apache-2.0) (triton_inference/service/requirements.txt).
