nnf_one_hot {torch}

One_hot

Description

Takes LongTensor with index values of shape ⁠(*)⁠ and returns a tensor of shape ⁠(*, num_classes)⁠ that have zeros everywhere except where the index of last dimension matches the corresponding value of the input tensor, in which case it will be 1.

Usage

nnf_one_hot(tensor, num_classes = -1)

Arguments

tensor

(LongTensor) class values of any shape.

num_classes

(int) Total number of classes. If set to -1, the number of classes will be inferred as one greater than the largest class value in the input tensor.
