# edge probe for `dinov2_vitb14`

A **trained probe head**, not a backbone. It is the small module VisBench fits
on top of frozen `dinov2_vitb14` features to measure what those features carry.

```python
import visbench
from visbench.hub import load_probe_from_hub

backbone = visbench.get_backbone("dinov2_vitb14")
probe = load_probe_from_hub("turhancan97/visbench-edge-dinov2_vitb14", backbone=backbone)
```

## It only works with this backbone

These weights were fitted on features from `dinov2_vitb14`, taken with
`pooling=mean` and `feature_mode=dense_only`. Loading them against
anything else is refused, because the failure is otherwise silent: a head fitted
on one pooling and fed another has the right shapes and produces a plausible,
wrong number.
