我有两个模拟，每个模拟产生一些我想要绘制的数据。当我添加第二个情节时，我得到的是一些非常奇怪的错误。目前，我的代码如下所示：
Do Some Simulation
kappa_density = stats.kde.gaussian_kde(kappa_estimate)
x = numpy.arange(0,0.0005,0.00001)
high_density =max(kappa_density(x))
fig = plt.figure(figsize=(10,6))
plt.plot(x,kappa_density(x))
plt.plot((kappa_central, kappa_central),(0,high_density), 'r--')
a = plt.Rectangle((0, 0), 0.25, 0.25,fc="red", alpha=1.00)
b = plt.Rectangle((0, 0), 0.25, 0.25,fc="blue",alpha=1.00)
plt.legend([a,b], ["Median","Density Estimate"],loc=1,fontsize='small')
plt.xlabel("Kappa",fontsize=16)
plt.ylabel("Density",fontsize=16)
plt.savefig('KappaEstimateDistribution.pdf')
Do some more simulation
fig2 = plt.figure(figsize=(10,6))
plt.hist(tau_estimate,facecolor='green', alpha=0.5)
plt.savefig('TauEstimateDistribution.pdf')
当它运行时，第一个图显示为我显示屏上的黑色未填充框，尽管它已正确保存为文件。第二次模拟完成，正确保存为文件......然后程序崩溃，吐出一系列惊人的警告和错误：

这是令人恼火的，而不是灾难性的，因为一旦它完成所有事情就会崩溃，但它仍然是一个奇怪的错误。任何人都可以看到我在做什么来触发这个吗？
