ModuleNotFoundError: No module named 'matplotlib'

#饼图
import matplotlib.pyplot as plt

# sizes 为数据大小
# explode 字面意思 就是每段 饼向外扩张的程度
# labels 是每个数据的标签名
# autopct 可以设置数据保留几位小数 '%1.0f%%'为零位 '%1.1f%%'位一位
# shadow 是否设置引用
# startangle 在二维立体坐标系哪个度数开始
labels = ['data1', 'data2', 'data3', 'data4', 'data5', 'data6']
sizes = [2, 5, 12, 70, 2, 9]
explode = (0, 0, 0, 0.2, 0, 0)
plt.pie(sizes, explode=explode, labels=labels, autopct='%1.0f%%', shadow=True, startangle=150)
# 设置 标题
plt.title("Example Pie")
plt.show()
