title: Check the progress while training the model using tqdm
body: <p>I know how to check the progression of iterations progress using tqdm:</p>
  
  <pre><code>for i in tqdm_notebook(range(100)):
  time.sleep(0.1)
  </code></pre>
  
  <p>I wanted to check the progress of training of my Random Forest model. Something like: </p>
  
  <pre><code>//tqdm_notebook starts the progress bar 
  RF_model=RandomForestRegressor(max_features='sqrt',n_estimators=100,oob_score=True)
  RF_model.fit(x_train,y_train)
  //tqdm_notebook stops the progress bar
  </code></pre>
