TensorFlowSharp 1.5.0

Your best source of information right now are the SampleTest that exercises various APIs of TensorFlowSharp, or the stand-alone samples located in "Examples".

You can also access the API documentation.

This API binding is closer design-wise to the Java and Go bindings which use explicit TensorFlow graphs and sessions. Your application will typically create a graph (TFGraph) and setup the operations there, then create a session from it (TFSession), then use the session runner to setup inputs and outputs and execute the pipeline.

Something like this:

using(var graph = new TFGraph ())
{
    graph.Import (File.ReadAllBytes ("MySavedModel"));
    var session = new TFSession (graph);
    var runner = session.GetRunner ();
    runner.AddInput (graph ["input"] [0], tensor);
    runner.Fetch (graph ["output"] [0]);

    var output = runner.Run ();

    // Fetch the results from output:
    TFTensor result = output [0];
}

In scenarios where you do not need to setup the graph independently, the session will create one for you. The following example shows how to abuse TensorFlow to compute the addition of two numbers:

using (var session = new TFSession())
{
    var graph = session.Graph;

    var a = graph.Const(2);
    var b = graph.Const(3);
    Console.WriteLine("a=2 b=3");

    // Add two constants
    var addingResults = session.GetRunner().Run(graph.Add(a, b));
    var addingResultValue = addingResults.GetValue();
    Console.WriteLine("a+b={0}", addingResultValue);

    // Multiply two constants
    var multiplyResults = session.GetRunner().Run(graph.Mul(a, b));
    var multiplyResultValue = multiplyResults.GetValue();
    Console.WriteLine("a*b={0}", multiplyResultValue);
}

Here is an F# scripting version of the same example, you can use this in F# Interactive:

#r @"packages\TensorFlowSharp.1.5.0\lib\net461\TensorFlowSharp.dll"

open System
open System.IO
open TensorFlow

// set the path to find the native DLL
Environment.SetEnvironmentVariable("Path", 
    Environment.GetEnvironmentVariable("Path") + ";" + __SOURCE_DIRECTORY__ + @"/packages/TensorFlowSharp.1.2.2/native")

module AddTwoNumbers = 
    let session = new TFSession()
    let graph = session.Graph

    let a = graph.Const(new TFTensor(2))
    let b = graph.Const(new TFTensor(3))
    Console.WriteLine("a=2 b=3")

    // Add two constants
    let addingResults = session.GetRunner().Run(graph.Add(a, b))
    let addingResultValue = addingResults.GetValue()
    Console.WriteLine("a+b={0}", addingResultValue)

    // Multiply two constants
    let multiplyResults = session.GetRunner().Run(graph.Mul(a, b))
    let multiplyResultValue = multiplyResults.GetValue()
    Console.WriteLine("a*b={0}", multiplyResultValue)
