DeepStack Beta - C# Guide

DeepStack is an AI server that empowers every developer in the world to easily build state-of-the-art AI systems both on premise and in the cloud. The promises of Artificial Intelligence are huge but becoming a machine learning engineer is hard. DeepStack runs on the docker platform and can be used from any programming language.

You can learn more about Docker on Docker’s Website Visit Docker Getting Started for instructions on setting up and using Docker for the first time.

DeepStack is developed and maintained by DeepQuest AI


Below, using DeepStack we attempt to classify the scene of the above image

using System;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;

namespace app

    class App {

    static HttpClient client = new HttpClient();

    public static async Task makeRequest(){

        var request = new MultipartFormDataContent();
        var image_data = File.OpenRead("image.jpg");
        request.Add(new StreamContent(image_data),"image",Path.GetFileName("image.jpg"));
        var output = await client.PostAsync("http://localhost:80/v1/vision/scene",request);
        var jsonString = await output.Content.ReadAsStringAsync();



    static void Main(string[] args){






{ success: true, label: 'highway', confidence: 63.377846 }

You simply send in an image by POST and deepstack returns a JSON response detailing the label of the image as well as the confidence of the prediction on a scale of 0 - 1.

Installing DeepStack - CPU Version

The code above demonstrates using DeepStack to predict the scene of an image, to run this, you can install DeepStack and start it with a single docker command.

Step 1: Install Docker

If you already have docker installed, you can skip this step.

On Linux

sudo apt-get update
sudo apt-get install curl
curl -fsSL -o && sh

On Windows or MacOS

Follow instructions on Docker Getting Started

Step 2: Install DeepStack

docker pull deepquestai/deepstack

Once installed, you can run DeepStack with the command below

docker run -e VISION-SCENE=True -v localstorage:/datastore -p 80:5000 deepquestai/deepstack

The command above runs deepstack with the scene recognition activated, once this is running, you can run the example above.

Step 3: Activate DeepStack

The first time you run deepstack, you need to activate it following the process below.

Once you initiate the run command above, visit localhost:80/admin in your browser. The interface below will appear.


You can obtain a free activation key from

Enter your key and click Activate Now

The interface below will appear.


This step is only required the first time you run deepstack.
