![]() Turn the original 3 That’s ok 2 The tensor of a column x Change it to 2 That’s ok 3 Column ![]() Notes : Broadcast mechanism For when two shapes 不 Identical Tensor When operating by element, First copy the elements appropriately so that the two Tensor After the shape is the same, operate according to the element. X,y There is 1 A for 1 Another dimension is greater than 1 position : Trigger broadcast mechanism X,y Are all 2 dimension : Differential multiplication X,y Are all 1 dimension : Point multiplication ![]() The corresponding position element is divided by Multiply the corresponding position elements Random 1 dimension [0,6) Integers are arranged randomly Random generation obeys N(0,1) Normal distribution 3 That’s ok 2 Column tensor Random generation obeys [0,1) Evenly distributed 3 That’s ok 2 Column tensor Generate a 3 That’s ok 2 Column space tensor Tensor (Tensor) It’s a vector 、 Matrix direction n Expansion of dimension, yes pytorch Data storage in 、 The main tool of transformation. The return value is False Then for CPU edition. Ĭheck whether the installation is successful import torch Mac It can be installed directly pytorch, The installation order can be found on the official website.
