Question: I have the following in Python: def ask_ollama(messages): """ Function to send the conversation to the Ollama API and get the response. """ payload = { 'model': 'llama3.2:1b', # Model ID 'messages': messages, # Pass the entire conversation history 'stream': False } response = requests.post( "http://localhost:11434/api/chat", # Ollama API URL json=payload ) raw_data = response.text data = json.loads(raw_data) message_content = data['message']['content'] return message_content def main(): parser = argparse.ArgumentParser() parser.add_argument('file_path', type=str) parser.add_argument('pre_question', type=str) args = parser.parse_args() # Initialize context from file context = "" with open(args.file_path, 'r', encoding="utf-8") as file: context = file.read() # Construct the initial question with context question = ( f"{context} would typically consist of plenty of paragraphs. " f"Scrutinize each of the paragraphs, and try to answer {args.pre_question}. " "Be patient, do not overlook any of those paragraphs. " "In some occasion, you need to group certain amounts of the paragraphs to answer the question, beware of it. " "If you have tried your best but still do not find any useful information from those paragraphs for the answer, " "then begin your response with 'it seems that there is no information that I am able to gain from the context' " "at the very first sentence and then elaborate what you know about the question according to your own knowledge." ) # Initialize the conversation history with the user's initial question conversation_history = [{'role': 'user', 'content': question}] # Get the initial response from the model response = ask_ollama(conversation_history) print(response) # Print the first response # Now enter a loop to handle follow-up questions while True: # Read the next follow-up question pre_follow_up_question = input() if pre_follow_up_question.lower() == 'exit': break follow_up_question = ( f"{context} would typically consist of plenty of paragraphs. " f"Scrutinize each of the paragraphs, and try to answer {pre_follow_up_question}. " "Be patient, do not overlook any of those paragraphs. " "In some occasion, you need to group certain amounts of the paragraphs to answer the question, beware of it. " "If you have tried your best but still do not find any useful information from those paragraphs for the answer, " "then begin your response with 'it seems that there is no information that I am able to gain from the context' " "at the very first sentence and then elaborate what you know about the question according to your own knowledge." ) # Append the follow-up question to the conversation history conversation_history.append({'role': 'user', 'content': follow_up_question}) # Get the follow-up response from Ollama using the updated conversation history response = ask_ollama(conversation_history) # Print the follow-up response print(response) main()  I am using C# to run this file, the code is like string filePath = @".\Uploads\Philosophy.txt"; string inputText = "What is philosophy of language?"; ProcessStartInfo startInfo = new ProcessStartInfo { FileName = "python", Arguments = $"Python_Ollama.py \"{filePath}\" \"{inputText}\"", RedirectStandardInput = true, RedirectStandardOutput = true, RedirectStandardError = true, UseShellExecute = false, CreateNoWindow = true }; using (Process process = Process.Start(startInfo)) { StreamReader reader = process.StandardOutput; StreamWriter writer = process.StandardInput; Console.WriteLine("Python Output:"); string line; while ((line = reader.ReadLine()) != null) { Console.WriteLine(line); } while (true) { Console.WriteLine("\nEnter a follow-up question (or type 'exit' to quit): "); string followUpQuestion = Console.ReadLine(); if (followUpQuestion.ToLower() == "exit") { break; } writer.WriteLine(followUpQuestion); writer.Flush(); while ((line = reader.ReadLine()) != null) { Console.WriteLine(line); } } }  the console of C# only showed the first response, it doesn't show the "Enter a follow..." and of course no way to let me to insert the follow-up question. First of all, I have tried ReadToEnd() (or ReadToEndAsync()) and it doesn't show up anything. And I used while ((line = reader.ReadLineAsync()) != null) { Console.WriteLine(line); }  the problem persists. If I used string output = await reader.ReadToEndAsync(); Console.WriteLine(output);  for the first part, then the sentence "Enter a follow..." is inserted in between of the response (the response is used to have plenty of paragraphs).

Answer: To put comments into an answer: First of all: you should consider calling the REST API directly from C#. That would probably solve a lot of problems revolving around this issue. But let's say you couldn't for a moment. Then you still have control over both parts: C# and Python. Which means you can do the following:  In the Python, append the api response with a specific string that cannot possibly be part of the api response. Let's say "=== End of API response ===".  In the C# code, instead of while ((line = reader.ReadLine()) != null) you do while ((line = reader.ReadLine()) != "=== End of API response ===")   That way you can detect the end of the response output without the need for the stream to be closed.
