Sam3dBodyEqx — converted weights

Pre-converted JAX/Equinox (.eqx) weights for Sam3dBodyEqx, a pure JAX/Equinox port of Meta's SAM 3D Body for single-image full-body 3D human mesh recovery. No PyTorch runtime is needed for inference.

Files

File	What it is	License
sam3d_body.eqx	Converted SAM 3D Body model (backbone + decoder + heads)	SAM License — see LICENSE.component.sam-3d-body
mhr.eqx	Converted Momentum Human Rig (MHR) forward-kinematics body model	Apache-2.0 — see LICENSE.component.mhr

These are converted forms of Meta's released models; the upstream licenses are preserved and redistributed here. The SAM License is maintained for sam3d_body.eqx (no military/nuclear/espionage or ITAR use; redistributions must include the license; patent litigation terminates the grant).

Licensing summary

• Weights (this repo): each file keeps its upstream license as in the table above.
• Inference code (the GitHub repo): original code is AGPL-3.0-or-later. The code license does not relicense these weights — they remain under SAM License / Apache-2.0 respectively.

Usage

from sam3d_body_eqx.mhr.mhr_model import MHRForwardKinematics

mhr = MHRForwardKinematics.from_pretrained(
    repo_id="peabody124/Sam3dBodyEqx", filename="mhr.eqx"
)
