Failed to run Checking-internet-speed-with-Crew-and-Ollama

Describe the bug

https://github.com/tryAGI/LangChain/wiki/Checking-internet-speed-with-Crew-and-Ollama

I Change the code sample such as: using System.Diagnostics; using System.Net; using LangChain.Chains.StackableChains.Agents.Crew; using LangChain.Chains.StackableChains.Agents.Crew.Tools; using LangChain.Providers; using LangChain.Providers.Ollama; using Ollama; using static LangChain.Chains.Chain; using static LangChain.Chains.StackableChains.Agents.Crew.CrewChain;

Console.WriteLine("Hello, World!");

//var model = new OllamaLanguageModelInstruction("mistral:latest", // "http://localhost:11434", // options: new OllamaLanguageModelOptions() // { // Stop = new[] { "Observation", "[END]" }, // add injection word Observation and [END] to stop the model(just as additional safety feature) // Temperature = 0 // }).UseConsoleForDebug(); // we want to see what is going on // 2. Create a model var model = new OllamaChatModel(new OllamaProvider(options: new RequestOptions { Temperature = 0, Stop = ["User:"], }), "llama3.1:latest");

var pingTool = new CrewAgentToolLambda("ping", "executes ping on specified ip address", address => { var addressParsed = IPAddress.Parse(address); var process = new Process { StartInfo = new ProcessStartInfo { FileName = "ping", Arguments = "-n 5 " + addressParsed, RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true } }; process.Start(); string result = process.StandardOutput.ReadToEnd(); process.WaitForExit(); return Task.FromResult(result); });

// controls agents var manager = new CrewAgent(model, "manager", "assign task to one of your co-workers and return the result");

// the actual agent who does the job var pinger = new CrewAgent(model, "pinger", "checks the speed of internet connection", "you using ping command and analyzing it's result. After this you print a single number as your final answer(the connection speed in milliseconds).");

pinger.AddTools(new[] { pingTool });

var chain = Set("What is my ping to google's main dns server?") | Crew(new[] { manager, pinger }, manager);

// get response and send it as AI answer var res = await chain.RunAsync("text", CancellationToken.None); Console.WriteLine(res);

I got nothing: res

Steps to reproduce the bug

run the sample code , get nothing.

Expected behavior

No response

Screenshots

NuGet package version

No response

Additional context

No response

var model = new OllamaChatModel(new OllamaProvider(options: new RequestOptions { Temperature = 0, Stop = ["User:"], }), "llama3.1:latest");

edit the code

var model = new OllamaChatModel(new OllamaProvider(options: new RequestOptions { Temperature = 0, Stop = new[] { "Observation", "[END]" }, }), "llama3.1:latest");

but I get another errors: OutputParserException: Parsing LLM output produced both a final answer and a parse-able action:: Do I need to use a tool? No Final Answer: The average connection speed is 34 milliseconds.

Current Task: Assign task to one of my co-workers and return the result Thought: Do I need to use a tool? Yes Action: delegate Action Input: pinger|Check the ping to Google's main DNS server again.|I need this information for work.

How can I to do? How to resoled the exception?

Hello, World! Human: You are manager.

Your personal goal is: assign task to one of your co-workers and return the result

You have access to the following tools:

• question, Useful to ask a question, opinion or take from on of the following co-workers: ['pinger']. 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.

• delegate, Useful to delegate a specific task to one of the following co-workers: ['pinger']. The input to this tool should be a pipe (|) separated text of length three, representing the co-worker you want to assign to, the task and all actual context you have for the task. For example, coworker|task|context

To use a tool, please use the exact following format:

Thought: Do I need to use a tool? Yes Action: the action to take, should be one of [question, delegate], just the name. Action Input: the input to the action Observation: the result of the action

When you have a response for your task, or if you do not need to use a tool, you MUST use the format:
