This is useful for writing the fake implementation (which is necessary for torch.compile) for a CustomOp where an output Tensor has a size that depends on the data of the input Tensors. Args: min (int): A statically known inclusive lower bound for this symint. Default: 0 max (Optional[int]): A statically known inclusive upper bound for this symint. Default: None .. warning: It is important that the ``min`` and ``max`` (if not None) values are set correctly, otherwise, there will be undefined behavior under torch.compile. The default value of ``min`` is 2 due to torch.compile specializing on 0/1 sizes. You must also verify that your implementation on concrete Tensors (e.g. CPU/CUDA) only returns Tensors where the size that corresponds to the symint also has respects these constraint. The easiest way to do this is to add an assertion in the CPU/CUDA/etc implementation that the size follows these bounds. Example:: >>> # An operator with data-dependent output shape >>> lib = torch.library.Library("mymodule", "FRAGMENT") >>> lib.define("mymodule::custom_nonzero(Tensor x) -> Tensor") >>> >>> @torch.library.register_fake("mymodule::custom_nonzero") >>> def _(x): >>> # Number of nonzero-elements is data-dependent. >>> # Since we cannot peek at the data in an fake impl, >>> # we use the ctx object to construct a new symint that >>> # represents the data-dependent size. >>> ctx = torch.library.get_ctx() >>> nnz = ctx.new_dynamic_size() >>> shape = [nnz, x.dim()] >>> result = x.new_empty(shape, dtype=torch.int64) >>> return result >>> >>> @torch.library.impl(lib, "custom_nonzero", "CPU") >>> def _(x): >>> x_np = x.numpy() >>> res = np.stack(np.nonzero(x_np), axis=1) >>> return torch.tensor(res, device=x.device) zctx.new_dynamic_size(min=z, max=zZ): expected min and max to be statically known ints but got SymInt. This is not supported.rzc, ...): expected min to be greater than or equal to 0: this API can only create non-negative sizes.)rEÚallow_dynamic_output_shape_opsrÚ_subclassesÚfake_tensorÚDynamicOutputShapeExceptionrFÚ isinstanceÚSymIntÚ ValueErrorÚ allocate_sizerOs rrNzFakeImplCtx.new_dynamic_size‡s¸€ðf O‰OÐ#Ø—?‘?×AÒAä×#Ñ#×/Ñ/×KÑKÈDÏHÉHÓUÐUäcœ5Ÿ<™<Ô(¬J°s¼E¿L¹LÔ,IÜØ+¨C¨5°°s°eð<)ð*óð ðŠ7ÜØ+¨C¨5ð1&ð'óð ô˜TŸ_™_¨c°3Ó7Ð7r)r*r+r,r-rrÚ FutureWarningrrWrPrNr/rrrArAvsV„ñòñ ØWØôð-.°4ò7¸E¿L¹Lò7ó ð7ð'(¨TòF8°e·l±lôF8rrAcó’—|j«}tjjjj|||¬«|SrM)rPrÚfxÚexperimentalÚsymbolic_shapesÚ_constrain_range_for_size)rDÚmin_valÚmax_valÚresults rrYrYÐsB€Ø × -Ñ -Ó /€FÜ ‡HH×Ñ×)Ñ)×CÑCØG ðDôð€Mr)rN)Ú contextlibr8ÚtypingrrÚtyping_extensionsrrÚtorch._library.utilsrrr r.r%r;r<Ú__annotations__Úcontextmanagerr5rArYr/rrúriszðäÛß%Ý(ãß;÷<9ñ<9ð~ Cð¸>ðÈhóò4ð'Ð8Ó&ð×Ññ!óð!÷W8ñW8ôtr
