What's the best way of checking whether a torch::Tensor is empty?
stackoverflow.com › questions › 63479765
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 :
