无法使用python查看矩阵图形的结果

import matplotlib.pyplot as plt
import numpy as np

# 创建一个随机矩阵
matrix = np.random.rand(10, 10)

# 绘制矩阵图形
plt.imshow(matrix, cmap='hot', interpolation='nearest')
plt.colorbar()

# 显示图形
plt.show()

import seaborn as sns
import numpy as np

# 创建一个随机矩阵
matrix = np.random.rand(10, 10)

# 绘制矩阵图形
sns.heatmap(matrix, cmap='YlGnBu')

# 显示图形
plt.show()

import plotly.graph_objects as go
import numpy as np

# 创建一个随机矩阵
matrix = np.random.rand(10, 10)

# 绘制矩阵图形
fig = go.Figure(data=go.Heatmap(z=matrix, colorscale='Viridis'))

# 显示图形
fig.show()
