'numpy.ndarray' object has no attribute 'columns'

引用中提到了解决'numpy.ndarray' object has no attribute 'columns'的方法，可以直接使用a.tolist()来处理数据。另外，引用中提到可以使用df.values或者np.array(df)来替代df.as_matrix()来查看版本。对于引用的问题，根据代码中的注释，需要使用一个包含八个元素的columns列表来循环，并使用sns.violinplot来绘制小提琴图。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
