ImportError：无法从“matplotlib.patches”导入名称“Patches”

Question

我正在尝试从视频中播放 plot，但出现以下错误 - ImportError: cannot import name 'Patches from 'matplotlib.patches'

导入错误

我的代码：

from colour import Color
import numpy as np
import matplotlib.pyplot as plt
import matplotlib
import matplotlib.patches as mpatches
from matplotlib.patches import Patches as mpatches

plt.figure(figsize=(12,5))
plt.scatter(X, Y, color='blue')

#DC
plt.scatter(X[0], Y[0],color='red', marker='D')
plt.annotate("DC",(X[0]-1,Y[0]-5.5))

#imprimir as rotas
for r in range(len(rotas)):
    for n in range(len(rotas[r])-1):
        i = rotas[r][n]
        j = rotas[r][n+1]
        plt.plot([X[i],X[j]], [Y[i],Y[j]], color=Color(r), alpha=0.4)
    
for r in range(len(temp_acum)):
for n in range(len(temp_acum[r])):
    i = rotas[r][n]
    plt.annotate('$q_{%d}=%d$ |$t_{%d}=%d$'  %(i, q[i], i, temp_acum[r][n]), (X[i]+1,Y[i]))
    
patch = [mpatches.Patch(color=Color(n), label="Veiculo "+str(truck[n])+"|cap="+str(Q[truck[n]])) for n in range(len(truck))]
plt.legend(handles=patch,loc='best')
plt.xlabel('Distância X')
plt.ylabel('Distância Y')
plt.title('CVRPTW | Problema de Roteamento de Veículos com Janela de Tempos')
     
plt.show()

Answer 1

正如@Matt 在评论中所说：

是的，应该是

from matplotlib.patches import Patch as mpatch

它是Patch而不是Patches
