10.06.2018 · Show activity on this post. -1 is a PyTorch alias for "infer this dimension given the others have all been specified" (i.e. the quotient of the original product by the new product). It is a convention taken from numpy.reshape (). Hence t.view (1,17) in the example would be equivalent to t.view (1,-1) or t.view (-1,17).

May 02, 2020 · 先说答案，reshape函数中-1代表的是n，什么意思呢，函数中另一个参数决定了-1的值，看下面三张图就很容易理解了定义34的张量，reshape(-1, 1)，你把它想象成要转换成n1的矩阵，那是多少？没错，最后转换成了12*1的矩阵同理，如果是reshape(1, -1)呢？那就是1*12了最后的一个更加直观，如果是reshape(2, -1)呢？

18.04.2021 · In this PyTorch tutorial, we are learning about some of the in-built functions that can help to alter the shapes of the tensors. We will go through the following PyTorch functions Reshape, Squeeze, Unsqueeze, Flatten, and View along with their syntax and examples.These functions will be very useful while manipulating tensor shapes in your PyTorch deep learning …

torch.reshape. torch.reshape(input, shape) → Tensor. Returns a tensor with the same data and number of elements as input , but with the specified shape. When possible, the returned tensor will be a view of input. Otherwise, it will be a copy. Contiguous inputs and inputs with compatible strides can be reshaped without copying, but you should ...

16.03.2017 · I think in Pytorch the way of thinking, differently from TF/Keras, is that layers are generally used on some process that requires some gradients, Flatten(), Reshape(), Add(), etc… are just formal process, no gradients involved, so you can just use helper functions like the ones in torch.nn.functional.*… There’s some use cases where a Reshape() layer can come in handy, …

Jun 11, 2018 · -1 is a PyTorch alias for "infer this dimension given the others have all been specified" (i.e. the quotient of the original product by the new product). It is a convention taken from numpy.reshape(). Hence t.view(1,17) in the example would be equivalent to t.view(1,-1) or t.view(-1,17).

01.09.2021 · In this article, we will discuss how to reshape a Tensor in Pytorch. Reshaping allows us to change the shape with the same data and number of elements as self but with the specified shape, which means it returns the same data as the specified array, but with different specified dimension sizes.
