title: File not found when loading dataset using Google Colab
body: <p>so I have written a pycharm project to do kernel regression on a dataset I downloaded to my computer, however, due to RAM issues I have had to switch to Google Colab. Whenever I run my main.py file from the drive, i get the error that it cannot find my dataset file. I've tried updating the directory in which I am searching, however, it still doesn't work. The code is as follows:</p>
  
  <pre><code>elif question == "1.2":
  
      with gzip.open(os.path.join('..', 'data', 'mnist.pkl.gz'), 'rb') as f:
          train_set, valid_set, test_set = pickle.load(f, encoding="latin1")
  
  
      X, y = train_set
      X = X.astype(np.float32)
      y = y.astype(np.float32)
  
  
      Xtest, ytest = test_set
      Xtest = Xtest.astype(np.float32)
      ytest = ytest.astype(np.float32)
  </code></pre>
