MatplotlibDeprecationWarning: Starting from Matplotlib 3.6, colorbar() will steal space from the mappable's axes, rather than from the current axes, to place the colorbar. To silence this warning, explicitly pass the 'ax' argument to colorbar().

plt.colorbar(net_info)

网上的办法都尝试过了,还是不行,这里是一段面向对象的代码,主要的是最后几条
在tkinter中显示出绘图的结果以及colorbar
