I want to judge whether a tensor is an empty tensor. ... len(empty_tensor) ==0. True ,I mean if there are other ways like if pytorch keyword about it.

When an empty tuple or list is passed into tensor() , it creates an empty tensor. The zeros() method. This method returns a tensor where all ...

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.

Jul 02, 2018 · torch.Tensor() is just an alias to torch.FloatTensor() which is the default type of tensor, when no dtype is specified during tensor construction. From the torch for numpy users notes, it seems that torch.Tensor() is a drop-in replacement of numpy.empty()

The function torch.empty() returns a tensor filled with uninitialized data. The shape of the tensor is defined by the variable argument size.

torch.is_tensor¶ torch. is_tensor (obj) [source] ¶ Returns True if obj is a PyTorch tensor.. Note that this function is simply doing isinstance(obj, Tensor).Using that isinstance check is better for typechecking with mypy, and more explicit - so it’s recommended to use that instead of is_tensor.

18.08.2020 · After some digging, it truns out that the best solution for this is to use .numel()method which returns the number of elements a tensor has. In summary: To know whether a tensor is allocated (type and storage), use defined(). To know whether an allocated tensor has zero elements, use numel()

torch.is_tensor¶ torch. is_tensor (obj) [source] ¶ Returns True if obj is a PyTorch tensor.. Note that this function is simply doing isinstance(obj, Tensor).Using that isinstance check is better for typechecking with mypy, and more explicit - so it’s recommended to use that instead of is_tensor.. Parameters. obj (Object) – Object to test. Example: >>> x = torch. tensor ([1, 2, 3 ...

In PyTorch torch.Tensor is the main tensor class. So all tensors are just instances of torch.Tensor. When you call torch.Tensor you will get an empty tensor w.

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. size (int...) – a sequence of integers defining the shape of the …

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.

A contiguous tensor is a tensor whose elements are stored in a contiguous order without leaving any empty space between them.

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

Tensor() vs torch.empty() in pytorch? ... FloatTensor() which is the default type of tensor, when no dtype is specified during tensor construction.

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 :
