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

torch.empty — PyTorch 1.10.0 documentation 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 · a. empty () api defined in pytorch is to create a tensor filed with uninitialized data. The meaning of is_empty () here will be ambiguous. b. The definition of empty tensor varies in different situation. Some people want it as undefined and some people just. want it as zero element. So we provide numel () and defined () separately.

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 :

torch.empty_strided. Returns a tensor filled with uninitialized data. The shape and strides of the tensor is defined by the variable argument size and stride respectively. torch.empty_strided (size, stride) is equivalent to torch.empty (size).as_strided (size, stride). More than one element of the created tensor may refer to a single memory ...

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..
