此代码不起作用并返回错误：

AttributeError: 'Rectangle' object has no property 'normed'

我认为它应该工作，因为它是复制粘贴从：
https://github.com/dashee87/blogScripts/blob/master/Jupyter/2017-06-04-predicting-football-results-with-statistical-modelling.ipynb

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt

epl_1617 = pd.read_csv("https://www.football-data.co.uk/mmz4281/1617/E0.csv")
epl_1617 = epl_1617[['HomeTeam','AwayTeam','FTHG','FTAG']]
epl_1617 = epl_1617.rename(columns={'FTHG': 'HomeGoals', 'FTAG': 'AwayGoals'})

poisson_pred = np.column_stack([[poisson.pmf(i, epl_1617.mean()[j]) for i in range(8)] for j in range(2)])

plt.hist(epl_1617[['HomeGoals', 'AwayGoals']].values, range(9), 
         alpha=0.7, label=['Home', 'Away'],normed=True, color=["#FFA07A", "#20B2AA"])

我使用的是Python 3.7和matplotlib 3.5.1
