Several plots in the metrics package trigger the matplotlib deprecation warning as they use the 'spectral' colormap by default.

skplt.metrics.plot_roc_curve(y_train, y_probas)

MatplotlibDeprecationWarning: The spectral and spectral_r colormap was deprecated in version 2.0. 
Use nipy_spectral and nipy_spectral_r instead.

Needs to be changed to 'nipy_spectral'
