For this purpose, we need to use thenumpy.argmax()method which returns the index of the maximum element along the row. To let the compiler know that we want the index of the maximum element along the rows of the

访问tensor中的数据类似于NumPy array。torch.cat方法可以将tensor按指定维度进行拼接。单元素tensor可通过其item()方法获取python中的数值。带有后缀"_"的操作为in-place操作,即使用结果来更新操作数,这样可以节省内存空间,但同时会丢失历史数据。 在CPU上,tensor和 Numpy array可以相互转换并共享底层内存,因此,改变其中...

Arithmetic and Data Alignment Sorting and Ranking Statistics Method Unique Value 本文用于学习pandas的一些基础,参考书籍《Python for Data Analysis》。pandas作为python中数据清洗和分析的工具,能够像Numpy一样基于array进行运算。不同的是,Numpy适合处理同构的数值数组,而pandas可以处理类似数据表的异构数据。
