Run Inference

The goal of building Computer Vision models is to run "inferences"; i.e. give the computer an image and ask it "tell me what you see!".

You can use the roboflow CLI to run inferences either with the models that you have trained on Roboflow, or with open source models available on Roboflow Universe.

By running roboflow infer in the command line, the Roboflow CLI will be sending images to the Roboflow API and print the results (predictions) in JSON format.

Let's look at an example using an open source model from Roboflow Universe. This is the poker-cards dataset - an open source Roboflow project that has a trained model capable of identifying poker cards.

poker-cards dataset on Roboflow Universe

From the URL in the browser:

• workspaceId="roboflow-100"

• projectId="poker-cards-cxcvz"

• version=1

Then if you have a local file with a card image you can run a command like

roboflow infer -c .70 -w roboflow-100 -m poker-cards-cxcvz/1 ~/Downloads/ace.jpg

running inference from the command line

And it's the same thing if you want to run inference with your own models. Just specify the workspace/project/version for a model that your user has access to.
