librosa.display.specshow has grids in its plots?

[Carlton Banks]

I am currently making plots with librosa, and for some reason are grids appearing in the dataset?...

librosa.display.specshow(interweaved.T,sr=16000,x_axis='frames',y_axis='mel',hop_length=160,cmap=cm.jet)
    plt.title("log mel power spectrum of interweaved " + name)
    plt.colorbar(format='%+02.0f dB')
    ax.grid(false)
    plt.savefig(plot+"/"+name+"_plot_interweaved_conv.png")
    plt.show()
    plt.close()

This is the plots it saves:

Those are due to matplotlib settings, not librosa.  Do you have axes.grid set in your matplotlib rc, by chance?  Or are you using a style (or seaborn) that enables grid lines by default?
