19.08.2020 · An empty tensor (that is the one created using torch::Tensor t; for example) returns zero when .numel() is used. while the size/sizes will result in an exception. This is a perefect check for such cases where an empty tensor (in the sense …

Because the structure loss expects a 4D tensor (NCHW), the tensors you're generating are 2D (only a height and width, H and W).

08.03.2018 · just beware that you can have a tensor with no elements and non-trivial size. t = torch.zeros(size=(1,0)) t.nelement() # returns zero, empty in this sense len(t.size()) # returns two, not empty in this sense!! len(t) # returns one, not empty in this sense!!

torch.empty. torch.empty(*size, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False, pin_memory=False, memory_format=torch.contiguous_format) → Tensor. Returns a tensor filled with uninitialized data. The shape of the tensor is defined by the variable argument size. Parameters.

Aug 19, 2020 · An empty tensor (that is the one created using torch::Tensor t; for example) returns zero when .numel() is used. while the size/sizes will result in an exception. This is a perefect check for such cases where an empty tensor (in the sense I just explained above) is returned one can simply do :

Currently the only way that seems to be working to check whether a tensor is empty or not, is to check its has_storage method. However, it seems ...

06.04.2020 · Python Pytorch empty () method. PyTorch is an open-source machine learning library developed by Facebook. It is used for deep neural network and natural language processing purposes. The function torch.empty () returns a tensor filled with uninitialized data. The shape of the tensor is defined by the variable argument size.

So we create a variable, x, which we assign to, torch.empty (1) This creates a one-dimensional tensor that contains one element. The output for x is then shown, which is, tensor ( [0.]) We then create another variable, y, which we assign to, torch.empty (3) This, again, creates a one-dimensional tensor, but this time consisting of 3 elements.
