html5 堆栈不足,Matplotlib动画TclError：堆栈空间不足（无限循环？）

我试图实现一个在非确定性区间上重绘的动画。我的想法是添加两个线程，一个打开图形，另一个线程处理从主线程推送的更新。Matplotlib动画TclError：堆栈空间不足(无限循环？)

import threading

import matplotlib.pyplot as plt

from Queue import Queue

import numpy

import time

class JobPlotter(object):

def __init__(self, log=None, **kwargs):

self.axes = None

self.lines = None

self.queue = Queue(maxsize=1)

self.fig = None

def update(self, data):

print 'Update'

self.queue.put(data)

def _draw_plot(self, labels, data):

self.fig = plt.figure()

self.axes = []

plt.ion()

for idx in range(len(labels)):

ax = self.fig.add_subplot(len(labels), 1, idx)

ax.plot(range(len(data[idx])), data[idx], label=labels[idx])

self.axes.append(ax)

print 'show'

self.fig.canvas.draw()

def setup(self):

print 'Setup: Start'

data = self.queue.get()

print 'Setup: Got Data'

labels = data[0]

data = numpy.array(data[1:]).T

data_plot = threading.Thread(None, self._draw_plot, 'PlotDraw', (labels, data))

data_plot.daemon = True

data_plot.start()

print 'Setup: Done'

while True:

self.loop()

def loop(self):

data = self.queue.get()

print 'Loop: Got Data'

labels = data[0]

data = numpy.array(data[1:]).T

for idx in range(len(labels)):

self.axes[idx].plot(range(len(data[idx])), data[idx], label=labels[idx])

self.fig.canvas.draw()

print 'Loop: Done'

if __name__ == '__main__':

foo = JobPlotter()

data_plot = threading.Thread(None, foo.setup, 'PlotDraw',())

data_plot.daemon = True

data_plot.start()

data = [['test'], [1], [2], [3], [4], [5], [6]]

while True:

temp = [[(x[0]*3) % 8] for x in data[1:]]

data = [data[0]]

data.extend(temp)

foo.update(data)

time.sleep(5)

代码运行，但死亡的第二呼叫的抽奖请求，以更新：

Setup: StartUpdate

Setup: Got Data

Setup: Done

show

Update

Loop: Got Data
