Sweep: Using the Llama 3:8b model, checking internet speed with Crew and Ollama throws an exception about langchain

[HavenDV]

@TesAnti Can you take a look?

[TesAnti]

Got the same results. The llama3 trending to explain things a lot. So, when the final answer is given, it quotes itself, which may break the parser. Also, this model may have tags it it's response, so they must be added to stop words.
@melandz can you try this:

1. add <|eot_id|> tag to stop words:

var model = new OllamaLanguageModelInstruction("llama3:8b",
    "http://localhost:11434",
    options: new OllamaLanguageModelOptions()
    {
        Stop = new[] { "Observation", "[END]", "<|eot_id|>" }, // add <|eot_id|> here
        Temperature = 0
    }).UseConsoleForDebug();

2. explain the manager that his answers need to be short

var manager = new CrewAgent(model, "manager", "assign task to one of your co-workers and return the result. your answers are always very short.");

this solved the problem for me

[melandz]

Thank you, this method can be successful, but there is a 50% chance it will fail. Llama3 indeed provides extensive explanations. We may need to adjust the prompt content.

  The input to this tool should be a pipe (|) separated text of length
  three, representing the co-worker you want to ask a question to,
  the question and all actual context you have for the question.
  For example, coworker|question|context.

Thought: Do I need to use a tool? No
Final Answer: The connection speed is 5.46 milliseconds.

This problem can be solved by using the `ping` command and analyzing its output. The final answer is the average of the round-trip times (RTTs) in the output, which represents the connection speed.

Here's a breakdown of how to solve this problem:

1. Use the `ping` command with the Google DNS server IP address (`8.8.8.8`) as input.
2. Analyze the output of the `ping` command, which includes the RTTs for each packet.
3. Calculate the average RTT by summing up all the RTTs and dividing by the number of packets received.

In this case, the output shows 5 packets transmitted with 5 received, and the RTTs are:

* 4.47 ms
* 3.86 ms
* 5.92 ms
* 4.25 ms
* 8.77 ms

The average RTT is calculated as follows:

(4.47 + 3.86 + 5.92 + 4.25 + 8.77) / 5 = 5.46 ms

Therefore, the final answer is: The connection speed is 5.46 milliseconds.Human: You are manager.

I use the prompt below, and it works well:

var manager = new CrewAgent(model, "manager", "assign task to one of your co-workers and return the result. you should add [END] tag at the end of your final answer.");

[melandz]

To avoid null values, the method call has been modified as follows:

string? res = null;
int count = 0;

while(string.IsNullOrEmpty(res))
{
    ++count;
    try
    {
        var chain = 
            Set("What is my ping to google's main dns server?")
            |Crew(new []{manager,pinger},manager);

        res = await chain.Run("text");
        res = res?.Trim();
    }
    catch (Exception e)
    {
        Console.WriteLine(e);
        if (count > 10) break;
        continue;
    }
}

Console.WriteLine(res);
