OWL-ViT is a transformer-based object detection model developed by Google Research.


To use OWL-ViT with autodistill, you need to install the following dependency:

pip3 install autodistill-owl-vit


from autodistill_owl_vit import OWLViT
from autodistill.detection import CaptionOntology

# define an ontology to map class names to our OWLViT prompt
# the ontology dictionary has the format {caption: class}
# where caption is the prompt sent to the base model, and class is the label that will
# be saved for that caption in the generated annotations
# then, load the model
base_model = OWLViT(
            "person": "person",
            "a forklift": "forklift"
base_model.label("./context_images", extension=".jpg")
