我正在使用pylab。那么它在使用from show_graph import display嗎？from pylab import *from numpy import outerfrom show_graph import displayrc('text', usetex=False)a=outer(arange(0,1,0.01),ones(10))figure(figsize=(10,5))subplots_adjust(top=0.8,bottom=0.05,left=0.01,right=0.99)maps=[m for m in cm.datad if not m.endswith("_r")]maps.sort()l=len(maps)+1for i, m in enumerate(maps):    subplot(1,l,i+1)    axis("off")    imshow(a,aspect='auto',cmap=get_cmap(m),origin="lower")    title(m,rotation=90,fontsize=10)savefig("colormaps.png",dpi=100,facecolor='gray')display("colormaps.png")但是當我嘗試跑步時，它說 no module named show_graph
