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.

In this article, we show how to make a an empty tensor in Python using PyTorch. A tensor is the equivalent of an array in numpy.

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

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..
