matplotlib报错：AttributeError: module 'backend_interagg' has no attribute 'FigureCanvas'. Did you mean: 'FigureCanvasAgg'?

  • 使用本地python环境可以成功执行
import pandas as pd
import matplotlib.pyplot as plt

# 设置字体
plt.rcParams['font.sans-serif'] = ['SimHei']
# 能正确显示负号
plt.rcParams['axes.unicode_minus'] = False
# 设置画布大小
plt.figure(figsize=(11, 8))

# 柱状图
path = r"C:\work\python\matplotlib_files\01.柱状图.xlsx"
data = pd.read_excel(path)
print(data)

# 排序
data.sort_values('分数', inplace=True, ascending=False)
# 绘制简单的柱形图
plt.bar(data.姓名, data.分数)
plt.show()
  • 切换为.conda\envs\dev环境后报错如下

  • 解决方案：matplotlib切换图形界面显示终端TkAgg
import pandas as pd

import matplotlib
matplotlib.use('TkAgg')
import matplotlib.pyplot as plt
