#76

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

提示

TypeError Traceback (most recent call last)

54 zz = 2 + xx*0;
55 caption = '$z - 2 = 0$';

14 surf = ax.plot_surface(xx,yy,zz,
15 facecolors=colors, shade=False)
16 surf.set_facecolor((0,0,0,0))

TypeError: FigureBase.gca() got an unexpected keyword argument 'projection'

改为

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

或

ax = plt.axes(projection='3d') 

后正常。

是的，Matplotlib改了三维绘图语法。这个要统一修改一次，7本书都会遇到这个问题

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

对这个报错，谢谢！

[Visualize-ML]

谢谢你，这个确实是旧的语法，已经不再支持，后续需要统一修改。请继续批评指正
