Step 2: Importing the Required Libraries

import threading
import subprocess
import time
from langchain_core.prompts import ChatPromptTemplate
from langchain_ollama.llms import OllamaLLM
from IPython.show import Markdown

Step 3: Working Ollama in Background on Colab

def run_ollama_serve():
  subprocess.Popen(["ollama", "serve"])

thread = threading.Thread(goal=run_ollama_serve)
thread.begin()
time.sleep(5)

The run_ollama_serve() operate is outlined to launch an exterior course of (ollama serve) utilizing subprocess.Popen().

The threading package deal creates a brand new thread that runs the run_ollama_serve() operate. The thread begins, enabling the ollama service to run within the background.
