代码如下：

    # 将方面列表和权重转化为文本
    aspects_text = " ".join([aspect for aspect, weight in aspects.items() for _ in range(weight)])
    
    # 创建WordCloud对象
    wordcloud = WordCloud(width=800, height=400, background_color='white').generate(aspects_text)
    
    # 显示云图
    plt.figure(figsize=(10, 5))
    plt.imshow(wordcloud, interpolation='bilinear')
    plt.axis("off")
    plt.show()

> 注意事项：
> 
> 1.  需要先下载包
> 2.  如果报错**ValueError: Only supported for TrueType fonts** —> **均是pillow包版本问题**  
>     直接终端输入指令：
> 
>     pip install pillow==9.3.0 -i https://pypi.tuna.tsinghua.edu.cn/simple
> 
> pillow包的版本问题！直接改成9.3.0的版本即可！建议使用清华镜像源安装
