在数据分析过程中,我遇到了一个错误,试图使用shape属性来查看一个列表的维度时,程序抛出了异常: my_list=[1,2,3]print(my_list.shape)# AttributeError: 'list' object has no attribute 'shape' 1. 2. 错误日志分析 以上代码在执行时,Python报错提示我们AttributeError表示列表对象并没有shap
python怎么看list有几个元素 python查看list的shape 这一阵在用python做DRL建模的时候,尤其是在配合使用tensorflow的时候,加上tensorflow是先搭框架再跑数据,所以调试起来很不方便,经常遇到输入数据或者中间数据shape的类型不统一,导致一些op老是报错。而且由于水平菜,所以一些常用的数据shape转换操作也经常百度了还是忘,所...
在使用Python进行数据处理或科学计算时,可能会遇到 AttributeError,尤其是在处理数组和矩阵时。这类错误通常发生在尝试访问对象不具备的属性上,如本文要讨论的错误:“AttributeError: ‘list’ object has no attribute ‘shape’”。本文将详细探讨此错误的成因、解决方案以及如何预防此类错误,帮助你更有效地使用Python进...
