EoMT (fastforks)

EoMT (Kerssies et al. 2025): encoder-only mask transformer, a plain ViT-L/16 whose last blocks also carry the mask queries; DINOv2 or DINOv3 pre-training, semantic ADE20K checkpoints.

This repo is the model card only: it holds no weights. fastforks downloads the authors' weights from the links below and checks them against the SHA-256 in the model card. Code: https://github.com/kleinicke/fastforks. Kernels for the kernels backend: https://huggingface.co/fastforks/kernels. Original code: https://github.com/huggingface/transformers at c4c4605f9618.

Author weight repos: https://huggingface.co/tue-mps/ade20k_semantic_eomt_large_512, https://huggingface.co/tue-mps/eomt-dinov3-ade-semantic-large-512.

Task: segmentation. Tier: stable. Outputs: logits. Backends: portable, kernels.

Input: one RGB image. Output: per-pixel class logits.

Variants

Weights are the authors' files (not hosted here). SHA-256 shortened to 12 hex digits; the full hashes are in card.toml.

Fixed-size cells: time (ms) / peak allocated / peak reserved memory (MiB).

Hardware, protocol and caveats: benchmarks (RTX 5060 Ti 16 GB, sm_120). Original = the authors' code at the precision of portable (fp16, or (fp32) where fp16 is unsupported or not finite); original fp32 = its default fp32 run. Peak memory is the torch allocator's.

Accuracy

Parity with the original code

Every variant is checked against golden outputs of the original code at its pinned commit. CPU, float32: max |diff| <= 0.002 vs the original. GPU, float16 (the default), portable and kernels: mean |diff| <= 0.0002 px and p99 <= 0.003 px.

Usage

from fastforks import segmentation

model = segmentation.load("eomt-l-dinov2-ade20k")  # portable PyTorch on the GPU if there is one, else the CPU
result = model("photo.jpg")
result.labels  # [H, W] per-pixel class index
result.backend  # what ran, e.g. Backend(mode='portable', device='cuda:0', dtype='float16')

Install with pip install fastforks (see https://github.com/kleinicke/fastforks). Other variants: eomt-l-dinov2-ade20k, eomt-l-dinov3-ade20k.

Kernels backend

segmentation.load("eomt-l-dinov2-ade20k", mode="kernels") runs our CUDA kernels (fastbb, seg_up). It needs a prebuilt kernel for your GPU architecture (downloaded from https://huggingface.co/fastforks/kernels on first use) and a recent NVIDIA driver; if there is none it raises BackendUnavailableError with the reason and never falls back silently. mode="auto" picks kernels when it can run and logs the choice.
