【Debug】MatplotlibDeprecationWarning: Calling gca() with keyword arguments was deprecated in 报错解决

完整报错信息如下：

MatplotlibDeprecationWarning: Calling gca() with keyword arguments was deprecated in Matplotlib 3.4. Starting two minor releases later, gca() will take no keyword arguments. The gca() function should only be used to get the current axes, or if no axes exist, create new axes with default keyword arguments. To create a new axes with non-default arguments, use plt.axes() or plt.subplot().
  ax = fig.gca(projection='3d')

解决方案：

将代码中的

ax = fig.gca(projection='3d')

改为：

ax = fig.add_subplot(projection='3d')
