    data = np.random.rand(8, 8)
    
    sns.set()
    # data:数据 square:是否是正方形 vmax:最大值 vmin:最小值 robust:排除极端值影响
    #sns.heatmap(data=grid, square=True, vmax=20, vmin=0, robust=True)
    ax = sns.heatmap(data, center=0, annot=False, vmax=1, vmin=0, robust=True)
    #plt.savefig('res.png', dpi=300)
    # 标题
    plt.title("test")
    plt.show()
