WebMar 9, 2024 · The dim argument is how you specify where the new axis should go. To put a new dimension on the end, pass dim=-1: x = torch.randn (3, 4) x = torch.unsqueeze (x, dim=-1) x.shape # Expected result # torch.Size ( [3, 4, 1]) Not bad. But you have to be careful if you use both NumPy and PyTorch because there is no NumPy unsqueeze () function: WebApr 15, 2024 · 1. scatter () 定义和参数说明. scatter () 或 scatter_ () 常用来返回 根据index映射关系映射后的新的tensor 。. 其中,scatter () 不会直接修改原来的 Tensor,而 scatter_ () 直接在原tensor上修改。. 官方文档: torch.Tensor.scatter_ — PyTorch 2.0 documentation. 参数定义:. dim:沿着哪个维 ...

On the surface, this may look like a very easy function but it does not work in an intuitive manner, thus giving headaches to beginners. ... dim : The dimension or the list of dimensions along which sum has to be applied. If not ... WebParameters: input ( Tensor) – the input tensor. dim ( int or tuple of ints, optional) – the dimension or dimensions to reduce. If None, all dimensions are reduced. keepdim ( bool) – whether the output tensor has dim retained or not. Keyword Arguments: out ( Tensor, optional) – the output tensor.
