model is required

[Aleksi-learn-code]

Hello, I don't understand, I have a code for practice:
`using System;
using System.Windows.Forms;
using System.Threading;
using System.Threading.Tasks;
using OllamaSharp;
using OllamaSharp.Models.Chat;

namespace OllamaChatApp
{
public partial class Form1 : Form
{
private Chat _chat; // Entferne readonly

    public Form1()
    {
        InitializeComponent();
        InitializeOllama();
    }

    private void InitializeOllama()
    {
        var ollamaApiClient = new OllamaApiClient("http://localhost:11434");
        _chat = new Chat(ollamaApiClient, "llama2");
    }

    private async void buttonsend_Click(object sender, EventArgs e)
    {
        if (string.IsNullOrWhiteSpace(richTextBoxinput.Text))
            return;

        string userInput = richTextBoxinput.Text;
        richTextBoxoutput.AppendText("You: " + userInput + Environment.NewLine);
        richTextBoxinput.Clear();

        richTextBoxoutput.AppendText("Assistant: ");
        buttonsend.Enabled = false;

        try
        {
            // Verwende die Methode Send für den Chat-Prozess
            var response = await _chat.Send(userInput, CancellationToken.None).StreamToEnd();
            richTextBoxoutput.AppendText(response);  // Zeigt die vollständige Antwort an
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            MessageBox.Show($"Error: {ex.Message}", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
        finally
        {
            richTextBoxoutput.AppendText(Environment.NewLine + Environment.NewLine);
            buttonsend.Enabled = true;
        }
    }
}

}

        var ollamaApiClient = new OllamaApiClient("http://localhost:11434");
        ollamaApiClient.SelectedModel = "llama3"; // Set Modell
       ollamaApiClient.
        _chat = new Chat(ollamaApiClient);

I guess you missed to tell us the error that occurs. Maybe Ollama doesn't have the model downloaded locally.

Sorry, the error was “model required”. I was able to solve this using the above code in the initialization
