SpletRecipe Objective. What is a torch tensor? Explain with an example. Here the Torch tensor is nothing but the matrix which contains the element of a single data type. The matrix is a multi-dimensional matrix. 10 tensor types are defined by the torch with CPU and GPU variants. The 10 different tensor types are: Integer. SpletTensor(张量)Tensor表示的是一个多维的矩阵。比如零维就是一个点，一维就是向量，二维就是一般的矩阵，多维就相当于一个多维的矩阵。这点和numpy是对应的，pytorch的Tensor可以和numpy的ndarray互相转换。唯一的区别是前者可以在GPU上运行，后者只能 … Splet24. mar. 2024 · 🐛 Describe the bug The bug happens when I try to use dist.send to send torch.cuda.ShortTensor.
