Ultralytics, the creators of YOLOv5, and Roboflow now support an integration making it easier to import YOLOv5 models from HUB to Roboflow, export datasets to Ultralytics HUB from Roboflow, and use custom trained model weights for model-assisted data labeling in Roboflow.

This integration builds on the established relationship of Roboflow being the official dataset management and annotation tool for YOLOv5. Roboflow’s integration into Ultralytics HUB is one of many integrations into the Roboflow platform which offers an extensible and interoperable approach to both tools and technologies in computer vision pipelines for customers.

Send Object Detection Datasets Directly to HUB for Custom Model Training

All Roboflow users now have the new Export option to send generated datasets to Ultralytics HUB.

After selecting Ultralytics HUB, users can continue by granting access to connect both accounts.

Users will be able to finish the import process within Ultralytics HUB by following the guided steps and then navigate to the dataset from within Ultralytics HUB at any point.

Use Custom Trained Models from HUB for Model-Assisted Labeling in Roboflow

To use datasets from Roboflow to train custom models in Ultralytics HUB, navigate to the Models page and start training. This is a straightforward Colab notebook with only two steps to follow.

After training is complete, utilize your HUB model for model-assisted labeling with Label Assist and label under-performing images as part of an active learning pipeline between Ultrayltics and Roboflow.

To use your Ultralytics HUB model in Roboflow, navigate to Settings and click on Integrations to insert your Roboflow API key.

If you're training YOLOv5 outside of Ultralytics HUB, you can use the step-by-step YOLOv5 tutorial notebook to train a model and upload weights to Roboflow as well.

The notebook will take you through how to:

#upload your model's weights back to Roboflow

The last step in the process is what you'll need to do to upload YOLOv5 weights to your Roboflow project.

Your custom model can be used to apply labels automatically for any new images in your dataset. This helps save time for future annotation jobs and makes it easier to improve your model with new data.


Roboflow and Ultralytics HUB Integration

Using Ultralytics HUB and Roboflow allows you to more easily bring datasets into Ultralytics HUB, train a custom model, and then use those model weights to automate labeling data in Roboflow.

When it comes to building computer vision pipelines, interoperability is important and we hope this new integration gives you and your team the flexibility you need to make your next computer vision project a success!
