Question

我试图在python中导入统计模块。它在我执行程序时给出了一条错误消息。

这是我的代码：

from statistics import mean
import numpy as np
import  matplotlib.pyplot as plt

xs = np.array([1,2,3,4,5,6,7,8])
ys = np.array([2,8,5,0,5,7,3,6])
def best_fit_line(xs ,ys):
    m = ( ((mean(xs)* mean(ys))- mean(xs*ys)) /
          (mean(xs)*mean(xs))-(mean(xs*xs)))
    return m
m = best_fit_line(xs,ys)

错误消息：

Traceback (most recent call last):
  File "/home/kudzai/Documents/Machine Learning/LinearRegAlg.py", line 1, in <module>
    from statistics import mean
ImportError: No module named statistics

Answer 1

在Python 3.4中添加了statistics module。也许您正在使用较旧的Python版本。

如果由于某种原因无法升级，您也可以使用.config的{{1}}函数：EBS等。对于numpy数组，它可能更快太

无法从统计信息中导入均值
