 Sometimes you will need to remake the .engine model. To do this you need to visit the [YoloV5's Github repo](https://github.com/ultralytics/yolov5) and download it. Then execute the `export.py` script in the repo with the command below. This can take up to 20 minutes and have no visual feedback. It's not frozen, just looks like it.

 ### Autoscaling workers
 
-ClearML comes with autoscalers too! This tool will automatically spin up new remote machines in the cloud of your choice (AWS, GCP, Azure) and turn them into ClearML agents for you whenever there are experiments detected in the queue. Once the tasks are processed, the autoscaler will automatically shut down the remote machines and you stop paying!
