Available checkpoints

Variant	Backbone	Stage	Hidden	Layers	Heads	Input
sarmae-vit-base-patch16-pretrain	ViT-B	pretrain	768	12	12	224
sarmae-vit-large-patch16-pretrain	ViT-L	pretrain	1024	24	16	224

Installation

pip install transformers timm torch torchvision safetensors huggingface_hub

Usage

Point transformers.pipeline or AutoModel.from_pretrained at a variant subfolder:

from transformers import pipeline

pipe = pipeline(
    task="image-feature-extraction",
    model="BiliSakura/SARMAE-transformers",
    revision="main",
    trust_remote_code=True,
    model_kwargs={"subfolder": "vit-base-patch16-pretrain"},
)
features = pipe(sar_image, pool=True, return_tensors=True)

Or load a variant directly:

from transformers import AutoModel

model = AutoModel.from_pretrained(
    "BiliSakura/SARMAE-transformers",
    subfolder="vit-base-patch16-pretrain",
    trust_remote_code=True,
)

Each variant folder is a self-contained model repository with:

• config.json (auto_map, custom_pipelines)
• model.safetensors
• preprocessor_config.json
• modeling_sarmae.py, image_processing_sarmae.py, pipeline_sarmae.py
