+#### Supported Adaptors:

+- RADIOv2.5: `clip`, `siglip`, `dino_v2`, `sam`
+- RADIOv2\[.1\]: `clip`, `dino_v2`, `sam`

+The `clip` and `siglip` adaptors have the additional functionality of supporting tokenization and language encoding. Refer to `examples/zero_shot_imagenet.py` for this use, as well as the [API](https://github.com/NVlabs/RADIO/blob/main/radio/open_clip_adaptor.py#L33-L36).

 ### Preprocessing
 
 By default, RADIO expects the input images to have normalized values in the `[0, 1]` range. If you already have an existing data pipeline, and you'd like conditioning to occur there instead of within the RADIO model, you can call this function:
