WebFor creating a two-dimensional tensor, you have first to create a one-dimensional tensor using arrange () method of the torch. This method contains two parameters of integer type. This method arranges the elements in tensor as per the given parameters. Web而Tensor提出的目的是能够创造更高维度的矩阵、向量。可以理解为：tensor就是pytorch中表示矩阵的一种数据形式，就像在numpy中创建的矩阵的数据格式是ndarray。 pytroch中 …
