WebJan 15, 2024 · When one source file calls a function from another source file or a library, all the compiler sees is the header file with the return type of the function, not the actual code of the function. This means when there is a function that returns a pointer, the compiler has no way to tell if the memory that the pointer is pointing to needs to be ... WebTo stop the compiler from compiling a method, add @torch.jit.ignore or @torch.jit.unused. @ignore leaves the. method as a call to python, and @unused replaces it with an exception. @ignored cannot be exported; @unused can. Most attribute types can be inferred, so torch.jit.Attribute is not necessary.
