AWS Quickstart
This guide will help new users run YOLOv5 on an Amazon Web Services (AWS) Deep Learning instance. AWS offers a Free Tier and a credit program for a quick and affordable start.
Other quickstart options for YOLOv5 include our Colab Notebook 
Create an account or sign in to the AWS console at https://aws.amazon.com/console/ and select the EC2 service.
In the EC2 section of the AWS console, click the Launch instance button.
Enter 'Deep Learning' in the search field and select the most recent Ubuntu Deep Learning AMI (recommended), or an alternative Deep Learning AMI. For more information on selecting an AMI, see Choosing Your DLAMI.
A GPU instance is recommended for most deep learning purposes. Training new models will be faster on a GPU instance than a CPU instance. Multi-GPU instances or distributed training across multiple instances with GPUs can offer sub-linear scaling. To set up distributed training, see Distributed Training.
Note: The size of your model should be a factor in selecting an instance. If your model exceeds an instance's available RAM, select a different instance type with enough memory for your application.
Refer to EC2 Instance Types and choose Accelerated Computing to see the different GPU instance options.
For more information on GPU monitoring and optimization, see GPU Monitoring and Optimization. For pricing, see On-Demand Pricing and Spot Pricing.
Amazon EC2 Spot Instances let you take advantage of unused EC2 capacity in the AWS cloud. Spot Instances are available at up to a 70% discount compared to On-Demand prices. We recommend a persistent spot instance, which will save your data and restart automatically when spot instance availability returns after spot instance termination. For full-price On-Demand instances, leave these settings at their default values.
Complete Steps 4-7 to finalize your instance hardware and security settings, and then launch the instance.
Select the checkbox next to your running instance, and then click Connect. Copy and paste the SSH terminal command into a terminal of your choice to connect to your instance.
Once you have logged in to your instance, clone the repository and install the dependencies in a Python>=3.7.0 environment, including PyTorch>=1.7. Models and datasets download automatically from the latest YOLOv5 release.
git clone https://github.com/ultralytics/yolov5 # clone
cd yolov5
pip install -r requirements.txt # installThen, start training, testing, detecting, and exporting YOLOv5 models:
python train.py # train a model
python val.py --weights yolov5s.pt # validate a model for Precision, Recall, and mAP
python detect.py --weights yolov5s.pt --source path/to/images # run inference on images and videos
python export.py --weights yolov5s.pt --include onnx coreml tflite # export models to other formatsAdd 64GB of swap memory (to --cache large datasets):
sudo fallocate -l 64G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
free -h # check memoryNow you have successfully set up and run YOLOv5 on an AWS Deep Learning instance. Enjoy training, testing, and deploying your object detection models!
