python matlotpib在重复显示曲面时出现递归错误

我使用matplotlib绘制曲面以显示一些三维数据。我使用“下一步”按钮滚动显示新数据的3d数据阵列。在大约43次滚动之后，我得到了一个递归错误，尽管没有明显的递归编程。此处更新了最小可再现示例（该示例不会滚动数据，但仍会再现错误：

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D 
import matplotlib.animation as animation
import matplotlib
from matplotlib import cm
import re
import time 
from threading import Thread
from matplotlib.widgets import Button


xsize=34
ysize=22
numDataLines = 0
#I realise the next 2 lines below are wrong but otherwise I get the wrong shape in use in plot_surface and contour3d
X = np.arange(0,ysize, 1)
Y = np.arange(0,xsize, 1) 
X,Y = np.meshgrid(X,Y)
currentFrameNumber = 0
zlines = []
zlines.append(np.reshape([0]*xsize*ysize, [xsize, ysize], 'C')) 

def display_plot(currentFrameNumber):
    Z = zlines[0]
    ax.clear()
    ax.set_zlim(0.0, 400.0)
    print "showing frame number ", currentFrameNumber
    ax.plot_surface(X, Y, Z, cmap="magma")
    plt.show() 

class Index(object):
    def next(self, event):
        display_plot(0)

fig = plt.figure()
#ax = plt.axes(projection='3d')
ax = fig.add_subplot(111, projection='3d')
ax.set_xlabel('x')
ax.set_ylabel('y')
ax.set_zlabel('z');

callback = Index()
axnext = plt.axes([0.81, 0.05, 0.09, 0.075])
bnext = Button(axnext, '>')
bnext.on_clicked(callback.next)
display_plot(0)


```

我得到这个错误：

如果删除plt.show（）命令，则不会得到错误。

我对python有点陌生，所以如果这是显而易见的，我深表歉意。

我们需要看到一个完整的回溯。我刚刚更新了一个最小的列表，其中重现了错误
