问题遇到的现象和发生背景

import pandas as pd
import matplotlib.pyplot as plt
plt.rcParams['font.sans-serif'] = ['SimHei']
data = pd.read_csv("avgHgt.csv")
x = (age for i in data)
y = (CHeight for i in data)
y = (JHeight for i in data)
plt.xlabel("年龄/岁")
plt.ylabel("身高/厘米")
plt.title("中日两国7-12岁男孩身高图")
plt.plot(x,y_zhongguo,label="中国男孩身高",color="b",linestyle="___")
plt.plot(x,y_riben,label="日本男孩身高",color="y",linestyle="___")
plt.figure(figsize=(20,8), dpi=100)
plt.plot(x,y)
plt.show()

用代码块功能插入代码，请勿粘贴截图

检查一下当前的环境，激活当前的环境并安装numpy

少了numpy模块，需要在命令行下输入 pip install numpy 进行安装一下，或者看下这篇文章

pip3 install numpy -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
