title: How to solve "No module named 'tools'" in google colab?
body: <p>I am trying to follow this tutorial to apply Bert in my data: <a href="https://medium.com/swlh/a-simple-guide-on-using-bert-for-text-classification-bbf041ac8d04" rel="nofollow noreferrer">https://medium.com/swlh/a-simple-guide-on-using-bert-for-text-classification-bbf041ac8d04</a> </p>
  
  <p>And Getting error on imports</p>
  
  <p>This is what I am importing</p>
  
  <pre><code>import torch
  import pickle
  from torch.utils.data import (DataLoader, RandomSampler, SequentialSampler, TensorDataset)
  from torch.nn import CrossEntropyLoss, MSELoss
  
  from tqdm import tqdm_notebook, trange
  import os
  from pytorch_pretrained_bert import BertTokenizer, BertModel, BertForMaskedLM, BertForSequenceClassification
  from pytorch_pretrained_bert.optimization import BertAdam, WarmupLinearSchedule
  
  from multiprocessing import Pool, cpu_count
  from tools import *
  import convert_examples_to_features
  </code></pre>
  
  <p>and getting error on:  from tools import * as "No module named 'tools'".</p>
  
  <p>I tried to follow some answers like: 
  <a href="https://stackoverflow.com/questions/51881295/python-caffe2-importerror-no-module-named-tools-setup-helpers-env">Python/Caffe2: ImportError: No module named tools.setup_helpers.env</a></p>
  
  <p><a href="https://stackoverflow.com/questions/14108428/pyserial-no-module-named-tools">pyserial: No module named tools</a></p>
  
  <p><a href="https://stackoverflow.com/questions/56859803/modulenotfounderror-no-module-named-tools-nnwrap">ModuleNotFoundError: No module named &#39;tools.nnwrap&#39;</a></p>
  
  <p>However, these answers didn't solve the error for me.</p>
  
  <p>Please help!</p>
