Thank you so much! We can find that the dimensions are arranged the same as using permute(), the order of the elements in the tensor will not change. In addition, view() can not only replace the order of dimensions, but also directly change the dimensions. For example, we can put all the elements just now in the same dimension: See more permute() is mainly used for the exchange of dimensions, and unlike view(), it disrupts the order of elements of tensors. Let’s take a look for an example: Output: This is a simple tensor arranged in numerical order with … See more Compared with permute(), view()does not disrupt the order of elements and is much more free.
