Bug

I have annotated 1,000 images in Roboflow (using instance segmentation), and when I tried to train the data using Google Colab with the preset snippet from Roboflow, it didn't work due to an error about an array. I looked for solutions through Gemini, GPT, Blackbox, Google, Stack Overflow, and GitHub, changing/adding/installing various things, but in the end, I still couldn't resolve it. I’ve been stuck here for four days, and I really need this to meet my project deadline next week. I also asked my friends who usually use Roboflow, and they suggested using YOLOv10. However, for some reason, they have the option to "Train with YOLOv10" on their accounts, while I only have YOLOv5 and YOLOv8. Please, your help would mean a lot to me and my career. Thank you!

Hello, I just followed the advice you gave! I exported the Roboflow dataset and selected the Ultralytics HUB format so I could train the data through Ultralytics HUB, but why is there no option for that?

@TepongLekTholang hello! 😊

Thanks for following up. It sounds like you're on the right track by exporting your dataset in the Ultralytics HUB format. If you're not seeing the option to train directly in the HUB, here are a few steps to help you proceed:

1. Verify Dataset Upload: Ensure your dataset is correctly uploaded to the Ultralytics HUB. You can do this by checking the Datasets section in your HUB account.

2. Create a Project: If you haven't already, create a new project in the HUB. This will allow you to organize and manage your dataset and models effectively.

3. Train a Model: Once your dataset is uploaded and your project is set up, you should be able to select your dataset and start training a model from the Models section.

If you're still encountering issues, please ensure you're using the latest version of the Ultralytics HUB. Sometimes updates can resolve unexpected behavior.

Feel free to reach out if you have any more questions or need further assistance. We're here to help! 🚀
