OSError: File not found

[0x6980]

Check this link https://evm-from-scratch.xyz/content/07a_opcodes/03_comparisions.
It seems call a file utils.ipynb which not found.

{
 "cells": [
  {
   "cell_type": "code",
   "execution_count": 12,
   "id": "2d075d2b",
   "metadata": {},
   "outputs": [],
   "source": [
    "%%capture\n",
    "%run utils.ipynb"
   ]
  },
  

should be delete that part of code or if necessary we should add the file utils.ipynb
