RMSE Calculation error

In notebook: streamflow_prediction_lstm/ee_streamflow_prediction_lstm.ipynb, calculation of rmse should be changed from rmse = np.mean(np.sqrt(np.power((y_test-y_pred),2))) to rmse = np.sqrt(np.mean(np.power((y_test-y_pred),2)))

in rmse, we calculate error in our predictions, then we square those errors, and then we get mean of squared errors, then finally we get square root of resulted mean.
