小编pet*_*tru的帖子

我写了一个函数,绘制了一个由两个不同大小的子图组成的图:

def draw_plot(data, function, sigma_value):

    gs = gridspec.GridSpec(1, 5)
    ax1 = subplot(gs[0, 0:3])  
    ax2 = subplot(gs[0, 3:5], sharey=ax1)                
    gs.update(wspace=0.05)
    ...

我应该提到这是一个模块级函数,因此在该模块的顶部我进行了导入

from pylab import *
import matplotlib.gridspec as gridspec

当我跑步时myplot.draw_plot(...),我明白了RuntimeError.事情是这种行为是不一致的.我可以调用该函数,比方说,三次,前两次我得到错误,而第三次运行OK.

追溯是
