python noob here。我试图重新创建这个例子
from mpl_toolkits.mplot3d import Axes3D
from matplotlib.collections import PolyCollection
import matplotlib.pyplot as plt, mpld3
from matplotlib import colors
from matplotlib.colors import colorConverter
import matplotlib.animation as animation
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
cc = lambda arg: colorConverter.to_rgba(arg, alpha=0.6)
xs = np.arange(0, 10, 0.4)
verts = []
zs = [0.0, 1.0, 2.0, 3.0]
for z in zs:
ys = np.random.rand(len(xs))
ys[0], ys[-1] = 0, 0
verts.append(list(zip(xs, ys)))
poly = PolyCollection(verts, facecolors = [cc('r'), cc('g'), cc('b'),
cc('y')])
poly.set_alpha(0.7)
ax.add_collection3d(poly, zs=zs, zdir='y')
ax.set_xlabel('X')
ax.set_xlim3d(0, 10)
ax.set_ylabel('Y')
ax.set_ylim3d(-1, 4)
ax.set_zlabel('Z')
ax.set_zlim3d(0, 1)
mpld3.show()
我想保存交互式情节(并将其发送给不使用python的人),所以mpld3.show()似乎可以做到这一点。只有我不断收到此错误

我明白这是因为某些东西是一个np数组而不是列表,但当我
时type(verts)
我得到了
<type 'list'>
所以我不确定那个&#34;数组([0,10。])&#34;是/如何解决这个问题。请提供有关如何提取/操作
类型对象的说明<class 'mpl_toolkits.mplot3d.art3d.Poly3DCollection'>
请原谅我的高傲。谢谢你们所有人。
答案 0 :(得分:4)
根据mpld3 github,&#34; mpld3&#34;目前不支持3D绘图,因此会产生您看到的错误
我遇到了你的问题,因为我正在寻找相同的解决方案(能够与没有Python的人分享交互式3D matplotlib情节)。我意识到这不是一个答案,但我认为它仍然值得分享? (我也是一个菜鸟,所以我甚至不能评论你的问题)
