创建一个动画热图，并在课堂上进行热图变化

Question

我在模拟伊辛模型时遇到了一个问题（不重要）。你知道吗

我的问题是二进制热图的动画，其中我的数组由一个函数调制：

似乎我的heatdata函数在动画中只被调用了一次：

'''IsingArray Class'''
import numpy as np
import random as rd
import functions as fun
import seaborn as sns
import matplotlib.pyplot as plt
import matplotlib.animation as animation

class IA:   
  def __init__(self,long):
      self.dim=long

      '''Array'''
      self.IsingArray=np.ndarray((self.dim,self.dim))


      '''Inititate Sites'''
      for i in range(self.dim):
          for j in range(self.dim):
              if rd.random()>=0.5:
                  self.IsingArray[i,j]=1
              else:
                  self.IsingArray[i,j]=-1
      self.raspl=0           
      self.fig = plt.figure()

  def heatdata(self,i):
          plt.clf()
          FP=sns.heatmap(self.IsingArray, linewidth=0.5,vmin=-1,vmax=1,cmap='bwr')
          colorbar=FP.collections[0].colorbar
          colorbar.set_ticks([-1,1])
          colorbar.set_ticklabels(['DOWN','UP'])`
          #replace 
          self.IsingArray[rd.randint(0,self.dim-1),rd.randint(0,self.dim-1)]=1
          self.raspl+=1


  def animate(self,nof,safe=False):
       animateMe = animation.FuncAnimation(self.fig, self.heatdata(self), nof,interval=100,repeat=False )
       if safe==True:
           animateMe.save('FieldChange'+'.mp4', fps=20, extra_args=['-vcodec', 'libx264'])
       plt.show()

long=5

Ising=IA(long)

print(Ising.raspl)
Ising.animate(10)
print(Ising.raspl)
