WebApr 18, 2024 · The reshape function in PyTorch gives the output tensor with the same values and number of elements as the input tensor, it only alters the shape of the output tensor as required by the user. But we have to make sure that the reshaped dimension should be able to hold all the elements of the original tensor otherwise it will give an error. WebDec 23, 2024 · Pytorch’s reshape function allows for the resizing of tensors. This is useful for when a tensor needs to be changed in order to fit a certain model or be compatible with another tensor. The function works by taking in the desired shape as a tuple and then adjusts the tensor to that shape. dr christopher ihionkhan longview tx

Web1 day ago · Pytorch Mapping One Hot Tensor to max of input tensor. I have a code for mapping the following tensor to a one hot tensor: tensor ( [ 0.0917 -0.0006 0.1825 -0.2484]) --> tensor ( [0., 0., 1., 0.]). Position 2 has the max value 0.1825 and this should map as 1 to position 2 in the One Hot vector. The following code does the job.
