connect vertex ai endpoint through .Net

Question

Is there any way to connected google cloud platform service vertex ai endpoint through .Net code ? I am new to gcp vertex. any help is really apricated.

Answer 1

You could refer to Google.Cloud.AIPlatform.V1 documentation for reference for dot net. You can start by:

1. Installing the package from Google AI Platform nuget
2. If you don't have an endpoint yet you can check out Google.Cloud.AIPlatform.V1.EndpointServiceClient. You can use this class to manage endpoints like create endpoint, delete endpoint, deploy endpoint, etc.
   • Check this EndpointServiceClient code sample for usage.
3. If you have an endpoint and you want to run predictions using it, you can check out Google.Cloud.AIPlatform.V1.PredictionServiceClient. You can use this class to perform prediction using your endpoint.
   • Specifically Predict(EndpointName, IEnumerable, Value, CallSettings) method where it accepts an endpoint as parameter.
   • Check this PredictionServiceClient code sample for usage.

Importantly! for Vertex AI you must specify a region endpoint when calling your custom trained model. See Java sample link.

const string regionEndpoint = "us-central1-aiplatform.googleapis.com:443";
try
{
    // Create client
    var serviceClientBuilder = new PredictionServiceClientBuilder
    {
        Endpoint = regionEndpoint
    };
    var predictionServiceClient = await serviceClientBuilder.BuildAsync();
    ...

}
