Pytorch tensor nonzero
WebApr 9, 2024 · Guarding works well for statically known sizes, but if you call an operator like torch.nonzero, it will produce a size that is only known at runtime. Our idea for how to handle this case is simple: we produce a symbolic size that has no underlying value (aka is “unbacked”), and instead error if we attempt to guard on this symbolic size.
