Installation

UMAP-Sharp ships as the UMAP NuGet package. It is a pure managed library with no native dependencies and multi-targets netstandard2.0, netstandard2.1, net7.0, net8.0, net9.0, and net10.0, so it runs on Windows, Linux, macOS, and ARM.

Install the package

dotnet add package UMAP

Install-Package UMAP

<PackageReference Include="UMAP" Version="*" />

paket add UMAP

Supported target frameworks

The library only depends on System.Memory for Span<T> support on the older targets. There are no native binaries.

Verify the install

Create a tiny console project and run the snippet below — it generates a 100-point random embedding to confirm the library is wired up correctly.

using UMAP;

var rng = new Random(42);
var vectors = Enumerable.Range(0, 100)
    .Select(_ => Enumerable.Range(0, 50)
        .Select(_ => (float)rng.NextDouble())
        .ToArray())
    .ToArray();

var umap = new Umap();
var epochs = umap.InitializeFit(vectors);
for (var i = 0; i < epochs; i++)
{
    umap.Step();
}

var embedding = umap.GetEmbedding();
Console.WriteLine($"Got {embedding.Length} embeddings of dimension {embedding[0].Length}");

You should see:

Got 100 embeddings of dimension 2
