Flattening a matrix in python
Webtorch.flatten¶ torch. flatten (input, start_dim = 0, end_dim =-1) → Tensor ¶ Flattens input by reshaping it into a one-dimensional tensor. If start_dim or end_dim are passed, only dimensions starting with start_dim and ending with end_dim are flattened. The order of elements in input is unchanged.. Unlike NumPy’s flatten, which always copies input’s … WebMar 16, 2024 · Keep in mind that the order parameter is optional. If you don’t use it in your syntax, it will default to order = 'C'. However, you have a few options for the order parameter. Let’s talk about two of them. order = ‘C’. If you set order = 'C', the flatten method will flatten the elements out in a row first fashion.
