 <p>This error is caused by overly large predictions that create an extremely large RMSE. The cell before you generate your submission runs <code>submission_df["Value"].describe()</code>, which returns some summary statistics of your predictions. Your maximum value for <code>Log Sale Price</code> should not be over 25.</p>
 <p>For your reference, a log sale price of 25 corresponds to a sale price of <span class="math inline">\(e^{25} \approx\)</span> 70 billion which is far bigger than anything found in the dataset.
