Train a Model

You can start model training from the command line. Training runs on Roboflow's cloud infrastructure.

Command

roboflow train start -p <project> -v <version> -t <model-type>

Or use the shorthand (without start):

roboflow train -p <project> -v <version> -t <model-type>

Options

Flag	Description
-p, --project	Project ID (required)
-v, --version	Version number (required)
-t, --type	Model type, e.g. yolov8n, rfdetr-nano
--checkpoint	Checkpoint to resume training from
--speed	Training speed preset
--epochs	Number of training epochs

Examples

Start training with a specific model type:

roboflow train start -p my-detector -v 3 -t yolov8n

Resume from a checkpoint:

roboflow train start -p my-detector -v 3 -t yolov8n --checkpoint my-checkpoint

JSON Output

roboflow train start -p my-detector -v 3 -t yolov8n --json
