Python PyTorch Tensor.narrow用法及代碼示例

本文簡要介紹python語言中 torch.Tensor.narrow 的用法。

用法:

Tensor.narrow(dimension, start, length) → Tensor

見 torch.narrow()

例子：

>>> x = torch.tensor([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
>>> x.narrow(0, 0, 2)
tensor([[ 1,  2,  3],
        [ 4,  5,  6]])
>>> x.narrow(1, 1, 2)
tensor([[ 2,  3],
        [ 5,  6],
        [ 8,  9]])
