这个错误是因为`FigureBase.gca()`方法不支持`projection`参数。你需要使用`add_subplot()`方法来创建一个3D子图，然后再将它设置为当前子图。修改代码如下： ```python import numpy as np import matplotlib.pyplot as plt from matplotlib import cm from mpl_toolkits.mplot3d import Axes3D fig = plt.figure() ax = fig.add_subplot(111, projection='3d') [x, t] = np.meshgrid(np.array(range(25)) / 24.0, np.arange(0, 575.5, 0.5) / 575 * 17 * np.pi - 2 * np.pi) p = (np.pi / 2) * np.exp(-t / (8 * np.pi)) u = 1 - (1 - np.mod(3.6 * t, 2 * np.pi) / np.pi) ** 4 / 2 y = 2 * (x ** 2 - x) ** 2 * np.sin(p) r = u * (x * np.sin(p) + y * np.cos(p)) h = u * (x * np.cos(p) - y * np.sin(p)) c= cm.get_cmap('spring_r') surf = ax.plot_surface(r * np.cos(t), r * np.sin(t), h, rstride=1, cstride=1, cmap= c, linewidth=0, antialiased=True) plt.show() ``` 这样应该就可以正常运行了。
