Thanks @smth for your quick response!
Given they are called builtin functions or classes or types, please correct me if I am wrong:


once import torch, these builtin functions are ready to use, correct?


if the above is correct, and given any is a builtin function of torch, then why I can’t find torch.any, or torch.tensor.any? Where is any to be found and be used?


all the keys of torch.builtins are here:
