ADE20K probe on CanViT's canvas (JAX / Flax NNX)

canvit/probe-ade20k-40k-s512-c64-in21k in the checkpoint format of canvit-nnx: an ADE20K segmentation probe for CanViT's canvas, loaded alongside the separately published CanViT checkpoint.

CanViT, the Canvas Vision Transformer, is an active-vision foundation model: it sees a scene through a sequence of glimpses and remembers it on a scene-wide canvas.

Usage

import jax.numpy as jnp
from PIL import Image

from canvit_nnx import CanViTForSemanticSegmentation, Viewpoint, sample_at_viewpoint
from canvit_nnx.preprocess import preprocess

scene = jnp.asarray(preprocess(512)(Image.open("scene.jpg").convert("RGB")))[None]
model = CanViTForSemanticSegmentation.from_pretrained_with_probe(
    pretrained_repo="canvit/canvitb16-add-vpe-pretrain-g128px-s512px-in21k-dv3b16-2026-02-02-nnx",
    probe_repo="canvit/probe-ade20k-40k-s512-c64-in21k-nnx",
)
model.eval()
state = model.init_state(batch_size=1, canvas_grid_size=64)
viewpoint = Viewpoint.full_scene(batch_size=1)
glimpse = sample_at_viewpoint(spatial=scene, viewpoint=viewpoint, glimpse_size_px=128)
logits, state = model(glimpse=glimpse, state=state, viewpoint=viewpoint)  # [1, 64, 64, 150]
