AttributeError: module 'matplotlib' has no attribute 'title'

引用所以当你运行代码时，会报错"AttributeError: module 'matplotlib.mlab' has no attribute 'normpdf'"。要解决这个问题，你可以使用scipy.stats.norm.pdf函数来替代mlab.normpdf来计算正态分布概率密度函数。修改代码如下：

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

mu = 100
sigma = 15
x = mu + sigma * np.random.randn(10000)
print("x:",x.shape)

num_bins = 50
n, bins, patches = plt.hist(x,num_bins,density=1,facecolor='green',alpha=0.5)
y = stats.norm.pdf(bins,mu,sigma)
plt.plot(bins,y,'r--')
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title('Histogram of IQ: $\mu=100$, $\sigma=15$')
plt.subplots_adjust(left=0.15)
plt.show()
print("bins:\n",bins)

这样修改后,你的代码应该能够正常运行，并且不会报"AttributeError: module 'matplotlib' has no attribute 'title'"错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
