04.09.2020 · pytorch中的repeat()函数可以对张量进行复制。当参数只有两个时，第一个参数表示的是复制后的列数，第二个参数表示复制后的行数。当参数有三个时，第一个参数表示的是复制后的通道数，第二个参数表示的是复制后的列数，第三个参数表示复制后的行数。

10.09.2019 · If I have a tensor A which has shape [M, N], I want to repeat the tensor K times so that the result B has shape [M, K, N] and each slice B[:, k, :] should has the same data as A. Which is the best practice without a for loop. K might be in other dimension. torch.repeat_interleave() and tensor.repeat() does not seem to work.

28.07.2021 · repeat 相当于一个broadcasting的机制 repeat(*sizes) 沿着指定的维度重复tensor。不同与expand()，本函数复制的是tensor中的数据。 import torch import torch.nn.functional as F import numpy as np a = torch.Tensor(128,1,512) B = a.repeat(1...

Oct 24, 2018 · The difference is that if the original dimension you want to expand is of size 1, you can use torch.expand () to do it without using extra memory. If the dimension you want to expand is of size more than 1, then you actually want to repeat what is at that dimension and you should use torch.repeat (). It will use extra memory (there is no way ...

torch.Tensor.repeat. Tensor.repeat(*sizes) → Tensor. Repeats this tensor along the specified dimensions. Unlike expand (), this function copies the tensor’s data. Warning. repeat () behaves differently from numpy.repeat , but is more similar to numpy.tile . For the operator similar to numpy.repeat, see torch.repeat_interleave ().

torch.Tensor.repeat. Tensor.repeat(*sizes) → Tensor. Repeats this tensor along the specified dimensions. Unlike expand (), this function copies the tensor’s data. Warning. repeat () behaves differently from numpy.repeat , but is more similar to numpy.tile . For the operator similar to numpy.repeat, see torch.repeat_interleave ().

I am trying to repeat a tensor in torch in two ways. For example repeating the tensor {1,2,3,4} 3 times both ways to yield; {1,2,3,4,1,2,3,4,1,2,3,4} {1,1,1,2,2,2,3,3,3,4,4,4} There is a built in torch:repeatTensor function which will generate the first of the two (like numpy.tile()) but I can't find one for the latter (like numpy.repeat()). I ...

24.10.2018 · Hi, Backprop-wise, they will give the exact same result. The difference is that if the original dimension you want to expand is of size 1, you can use torch.expand() to do it without using extra memory. If the dimension you want to expand is of size more than 1, then you actually want to repeat what is at that dimension and you should use torch.repeat().

02.02.2019 · An alternative way is to use torch.repeat (). So with torch.repeat (), you can specify the number of repeats for each dimension: >>> a = torch.randn (8, 3, 224, 224) >>> b = a.repeat (3, 1, 1, 1) >>> b.shape torch.Size ( [24, 3, 224, 224]) Sorry for the confusion. I omit to mention that the same element should be in succession.
