Train a YOLOv12 model on Google Colab and upload it to Roboflow

Build your own model for inference

In our previous post about Roboflow, we looked at how Vector can use models at Roboflow Universe to identify objects or hand gestures seen using its camera. By using a model from Roboflow Universe, we played a game of rock, scissors, and paper with Vector using hand gestures. We also used Roboflow hosted training to build a YOLOv12 model which could be used to let Vector detect another Vector robot.

Train your model for free

One financial constraint you might face is that you need to pay to train a model using Roboflow hosted training. You also don’t get the feel of training your own machine learning model… because Roboflow does it automatically for you. You cannot play with the different variables such as choosing the size of the model, choose the number of epochs, or checking the loss curves (the magnitude of error that a machine learning model has). Training an efficient machine learning model both an art and a science, and you don’t get to learn the art.

Luckily, there is an alternat…
