Suppress scientific notation in sklearn.metrics.plot_confusion_matrix

Simply pass values_format='' Example:

plot_confusion_matrix(clf, X_test, Y_test, values_format = '')

In case anyone using seaborn´s heatmap to plot the confusion matrix, and none of the answers above worked. You should turn off scientific notation in confusion matrix seaborn with fmt='g', like so:

sns.heatmap(conf_matrix,annot=True, fmt='g')

Just remove ".format" and the {} brackets from your call parameter declaration:

disp = plot_confusion_matrix(logreg, X_test, y_test,
                                 display_labels=class_names,
                                 cmap=plt.cm.Greens,
                                 normalize=normalize, values_format = '.5f')

In addition, you can use '.5g' to avoid decimal 0's
