我正在使用pylab. 那么它在使用from show_graph import display吗？ 

from pylab import *
from numpy import outer
from show_graph import display
rc('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)+1
for 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")

但是当我试图跑进去时，它说no module named show_graph

您应该删除from show_graph import display，因为此导入会引发ImportError. 然后你保存和显示情节的代码可能是这样的

from pylab import *
from numpy import outer
rc('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)+1
for 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')
show()
