The torch package contains data structures for multi-dimensional tensors and defines mathematical operations over these tensors. Additionally, it provides many utilities for efficient serializing of Tensors and arbitrary types, and other useful utilities.

torch.stack(sequence, dim) sqequence– 待连接的张量序列 dim (int) – 插入的维度。torch.stack()函数和torch.cat()有所不同，torch.stack()并不在已有的维度进行拼接，而是沿着新的维度进行拼接。我在使用torch.stack()产生了两个问题： 1.怎么确定新的维度产生在哪里？2.指定了新维度后要怎么拼接？

stack: Concatenates sequence of tensors along a new dimension. I like to think of this as the torch "append" operation since you can index/get ...

23.03.2021 · torch.stack (tensors, dim=0, *, out=None) → Tensor 作用： Concatenates a sequence of tensors along a new dimension. All tensors need to be of the same size. 把一系列tensor沿着新的维度堆起来。 注意要tensor都一样的size，并且会增加一个维度。 默认，dim=0.

torch.vstack torch.vstack(tensors, *, out=None) → Tensor Stack tensors in sequence vertically (row wise). This is equivalent to concatenation along the first axis after all 1-D tensors have been reshaped by torch.atleast_2d (). Parameters tensors ( sequence of Tensors) – sequence of tensors to concatenate Keyword Arguments

torch.stack(tensors, dim=0, *, out=None) → Tensor Concatenates a sequence of tensors along a new dimension. All tensors need to be of the same size. Parameters tensors ( sequence of Tensors) – sequence of tensors to concatenate dim ( int) – dimension to insert. Has to be between 0 and the number of dimensions of concatenated tensors (inclusive)

May 18, 2021 · The Hidden Markov Model. Consider a sensor which tells you whether it is cloudy or clear, but is wrong with some probability. Now, the weather *is* cloudy or clear, we could go and see which it was, so there is a “true” state, but we only have noisy observations on which to attempt to infer it.

torch.vstack¶ torch. vstack (tensors, *, out = None) → Tensor ¶ Stack tensors in sequence vertically (row wise). This is equivalent to concatenation along the first axis after all 1-D tensors have been reshaped by torch.atleast_2d().
