我尝试从网站https://plot.ly/scikit-learn/plot-kmeans-silhouette-analysis/运行代码。当我运行时，事实证明matplotlib模块已经不具有光谱属性。我读到inforum的另一个属性已被省略。我该如何更换？我已经尝试过c.get_cmp，cm.nipy_sepctral，plt.cm.spectral。但仍然是一个错误。这就是所有代码：

import plotly.plotly as py
import plotly.graph_objs as go
from plotly import tools

from __future__ import print_function

from sklearn.datasets import make_blobs
from sklearn.cluster import KMeans
from sklearn.metrics import silhouette_samples, silhouette_score

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.cm as cm
import numpy as np

print(__doc__)

# This particular setting has one distinct cluster and 3 clusters placed close
# together.
X, y = make_blobs(n_samples=500,
                  n_features=2,
                  centers=4,
                  cluster_std=1,
                  center_box=(-10.0, 10.0),

                  random_state=1)  # For reproducibility
