Deploy Computer Vision Models

Deploy YOLOv5 Object Detection Models to AWS EC2

Once you have a computer vision model that achieves the requisite level of performance for your production use case, the next question to answer is "how can I deploy the model?"

Roboflow offers a range of SDKs with which you can deploy object detection, classification, and segmentation models.

In this guide, we are going to show how to deploy a


model to


using the Roboflow Inference Server. This SDK works with


models trained on both Roboflow and in custom training processes outside of Roboflow.

To deploy a


model to


, we will:

1. Train a model on (or upload a model to) Roboflow
2. Download the Roboflow Inference Server
3. Install the Python SDK to run inference on images
4. Try out the model on an example image

Let's get started!

Train a Model on or Upload a Model to Roboflow

If you want to upload your own model weights, first create a Roboflow account and create a new project. When you have created a new project, upload your project data, then generate a new dataset version. With that version ready, you can upload your model weights to Roboflow.

Download the Roboflow Python SDK:

pip install roboflow

Then, use the following script to upload your model weights:

from roboflow import Roboflow

home = "/path/to/project/folder"

rf = Roboflow(api_key=os.environ["ROBOFLOW_API_KEY"])
project = rf.workspace().project("PROJECT_ID")

project.version(PROJECT_VERSION).deploy(model_type="yolov5", model_path=f"/{home}/yolov5/runs/train/")

You will need your project name, version, API key, and model weights. The following documentation shows how to retrieve your API key and project information:

- Retrieve your Roboflow project name and version
- Retrieve your API key

Change the path in the script above to the path where your model weights are stored.

When you have configured the script above, run the code to upload your weights to Roboflow.

Now you are ready to start deploying your model.

Set up a EC2 Virtual Machine

First, we need to create an AWS EC2 instance. EC2 is Amazon’s compute product that you can use to deploy virtual machines. Search for “EC2” in the search bar and navigate to EC2.

On the EC2 homepage, click the “Launch instance” button:

This button will take you to a page where you can configure the machine to create.

We recommend choosing the Amazon Linux operating system, which has been optimized for use in AWS. If you plan to use Inference on a GPU device, we recommend choosing a machine image optimized for deep learning, such as the Deep Learning Base GPU AMI image. This image will come with some tooling out of the box that will minimize GPU setup. If you want to deploy on a CPU device, the standard Amazon Linux operating system is recommended.

Once you have configured the virtual machine, you can deploy the system.

Next, sign in to your server with SSH. Read the AWS EC2 SSH instructions to learn more.

Download the Roboflow Inference Server

The Roboflow Inference Server allows you to deploy computer vision models to a range of devices, including



The Inference Server relies on Docker to run. If you don't already have Docker installed on the device(s) on which you want to run inference, install it by following the official Docker installation instructions.

Once you have Docker installed, run the following command to download the Roboflow Inference Server on your



Now you have the Roboflow Inference Server running, you can use your model on



Install the Roboflow Python SDK

The Roboflow Inference Server provides a HTTP API with a range of methods you can use to query your model and various popular models (i.e. SAM, CLIP). You can read more about all of the API methods available on the Roboflow Inference server in the Inference Server documentation.

The Roboflow Python SDK provides abstract convenience methods for interacting with the HTTP API. In this guide, we will use the Python SDK to run inference on a model. You can also query the HTTP API itself.

To install the Python SDK, run the following command:

pip install roboflow

Run Inference on an Image

With the Python SDK installed, you can run inference on your model in a few lines of Python code.

The following code will run inference on the model hosted on Roboflow and return a JSON object with predictions:

from roboflow import Roboflow
rf = Roboflow(api_key="API_KEY")
project = rf.workspace().project("PROJECT_NAME")
model = project.version(MODEL_VERSION, local="http://localhost:9001").model

# infer on a local image
print(model.predict("your_image.jpg", confidence=40, overlap=30).json())

# visualize your prediction
# model.predict("your_image.jpg", confidence=40, overlap=30).save("prediction.jpg")

# infer on an image hosted elsewhere
# print(model.predict("URL_OF_YOUR_IMAGE", hosted=True, confidence=40, overlap=30).json())

Substitute the model name, version, and API key with the values associated with your Roboflow account and project, then run the script.
