Train a Model

Grounding DINO is a zero-shot object detection model developed by IDEA Research. You can distill knowledge from Grounding DINO into a smaller model using Autodistill.

In this guide, we show how to train a computer vision model without labelling using these two models.

Use Grounding DINO to train a Object Detection model

Autodistill allows you to use state-of-the-art foundation models that know a lot about a variety of objects to label data for your project. You can then train a new model with your labeled data. This whole process uses around a dozen lines of code.

To learn more about how autodistill works, read our overview guide or watch our YouTube tutorial.

In this guide, we will show you how to use

Grounding DINO

to train a

model.



To use

Grounding DINO
to train a
model, we will:

1. Install autodistill
2. Create a dataset
3. Find a prompt to label images in the dataset
4. Label our data with autodistill
5. Train a new
model

In this guide, we will show you how to label data with

.



To label data with

Grounding DINO
, we will:

1. Install autodistill
2. Create a dataset
3. Find a prompt to label images in the dataset
4. Label our data with autodistill


Let's get started!

Step #1: Install Dependencies

First, install the following packages:

pip install autodistill autodistill-grounding-dino

Step #2: Create a Dataset

Before you can label a dataset, you need a dataset with which to work.

Roboflow has a few resources that can help you create a dataset for your project:

You can use any folder of images you have on your local machine with Autodistill, too.

Step #3: Label Images with Grounding DINO

Autodistill has two model types:

  1. A Base Model, which automatically labels your data, and;
  2. A Target Model, which trains on your labeled data.

To label your dataset with a Base Model, you need to provide prompt(s) that are relevant to the classes you want to label.

Replace "example" below with the prompt you want to use. Replace "class" with the name of the class you want the prompt results to be saved as in your dataset. Also, replace the IMAGE_NAME with an image from your dataset.

The code cell below loads the base model with your prompt on the provided image, then visualizes the results.

You may need to experiment with a few prompts.


from autodistill_grounding_dino import GroundingDINO
from autodistill.detection import CaptionOntology

base_model = GroundingDINO(ontology=CaptionOntology({"shipping container": "container"}))

IMAGE_NAME = "valid/images/image.jpg"

image = os.path.join(DATASET_NAME, IMAGE_NAME)

predictions = base_model.predict(image)

image = cv2.imread(image)

annotator = sv.BoxAnnotator()

annotated_image = annotator.annotate(scene=image, detections=predictions)

sv.plot_image(annotated_image)

Step #4: Label Data

To start labeling your images with

Grounding DINO

, run the following lines of code:

base_model.label(input_folder="./images", output_folder="./dataset")

Step #5: Train a Model

To train a

model using your newly-labeled dataset, run the following code:

After running this cell, you will have model weights that you can use to run inference on your new model.

Step #5: Upload Model to Roboflow (Optional)

You can deploy your trained model to Roboflow. By deploying your model to Roboflow, you can run inference on our infinitely-scalable API. As your inference demands grow, our you will continue to see high levels of performance thanks to autoscaling infrastructure that is always on.

Roboflow offers:

Fully managed, infinitely-scalable APIs for deployed models

SDKs for common deployment targets (NVIDIA Jetson, Luxonis OAK, Docker, and more)

SOC II Type 1 Compliant

Trusted by 250,000+ developers

To deploy your model to Roboflow, run the following code:

Deploy your model with Roboflow

Through Roboflow, you can deploy your model to a range of targets. Below, we have listed devices to which you can deploy your model using Roboflow SDKs.
