Pytorch index select 2d
WebDec 31, 2024 · torch.index_select solves your problem more easily than torch.gather since you don't have to adapt the dimensions of the indeces. Indeces must be a tensor. For your case indeces = [0,2] a = torch.rand (size= (3,3,3)) torch.index_select (a,dim=1,index=torch.tensor (indeces,dtype=torch.long)) Share Improve this answer Follow WebApr 11, 2024 · 要修改特定数量的通道或将图片数据的输入张量中多个通道改为一个通道，可以使用PyTorch中的操作。 1. 修改特定数量的通道： 可以使用torch.index_select()函数和torch.cat()函数。

WebApr 8, 2024 · Using the PyTorch framework, this two-dimensional image or matrix can be converted to a two-dimensional tensor. In the previous post, we learned about one-dimensional tensors in PyTorch and applied some useful tensor operations. In this tutorial, we’ll apply those operations to two-dimensional tensors using the PyTorch library. WebJul 18, 2024 · There are two types of index-based operations in PyTorch, one is in-place operations and the other is out-of-place operations. The basic difference between the two is in-place operation directly changes the values of the tensors without making any copy of that whereas out of place operations don’t. Following are the operations:- index_add_
