In PyTorch, defining an op (short for "operator") is a two step-process: - we need to define the op (by providing an operator name and schema) - we need to implement behavior for how the operator interacts with various PyTorch subsystems, like CPU/CUDA Tensors, Autograd, etc. This entrypoint defines the custom operator (the first step) you must then perform the second step by calling various ``impl_*`` APIs, like :func:`torch.library.impl` or :func:`torch.library.register_fake`. Args: qualname (str): The qualified name for the operator. Should be a string that looks like "namespace::name", e.g. "aten::sin". Operators in PyTorch need a namespace to avoid name collisions; a given operator may only be created once. If you are writing a Python library, we recommend the namespace to be the name of your top-level module. schema (str): The schema of the operator. E.g. "(Tensor x) -> Tensor" for an op that accepts one Tensor and returns one Tensor. It does not contain the operator name (that is passed in ``qualname``). lib (Optional[Library]): If provided, the lifetime of this operator will be tied to the lifetime of the Library object. tags (Tag | Sequence[Tag]): one or more torch.Tag to apply to this operator. Tagging an operator changes the operator's behavior under various PyTorch subsystems; please read the docs for the torch.Tag carefully before applying it.

Also sometimes known as a "meta kernel", "abstract impl". An "FakeTensor implementation" specifies the behavior of this operator on Tensors that carry no data ("FakeTensor"). Given some input Tensors with certain properties (sizes/strides/storage_offset/device), it specifies what the properties of the output Tensors are. The FakeTensor implementation has the same signature as the operator. It is run for both FakeTensors and meta tensors. To write a FakeTensor implementation, assume that all Tensor inputs to the operator are regular CPU/CUDA/Meta tensors, but they do not have storage, and you are trying to return regular CPU/CUDA/Meta tensor(s) as output. The FakeTensor implementation must consist of only PyTorch operations (and may not directly access the storage or data of any input or intermediate Tensors). This API may be used as a decorator (see examples).

In order for an operator to work with autograd, you need to register a backward formula: 1. You must tell us how to compute gradients during the backward pass by providing us a "backward" function. 2. If you need any values from the forward to compute gradients, you can use `setup_context` to save values for backward. ``backward`` runs during the backward pass. It accepts ``(ctx, *grads)``: - ``grads`` is one or more gradients. The number of gradients matches the number of outputs of the operator. The ``ctx`` object is `the same ctx object `_ used by :class:`torch.autograd.Function`. The semantics of ``backward_fn`` are the same as :meth:`torch.autograd.Function.backward`. ``setup_context(ctx, inputs, output)`` runs during the forward pass. Please save quantities needed for backward onto the ``ctx`` object via either :meth:`torch.autograd.function.FunctionCtx.save_for_backward` or assigning them as attributes of ``ctx``. If your custom op has kwarg-only arguments, we expect the signature of ``setup_context`` to be ``setup_context(ctx, inputs, keyword_only_inputs, output)``. Both ``setup_context_fn`` and ``backward_fn`` must be traceable. That is, they may not directly access :meth:`torch.Tensor.data_ptr` and they must not depend on or mutate global state. If you need a non-traceable backward, you can make it a separate custom_op that you call inside ``backward_fn``. If you need different autograd behavior on different devices, then we recommend creating two different custom operators, one for each device that needs different behavior, and switching between them at runtime. Examples: >>> import torch >>> import numpy as np >>> from torch import Tensor >>> >>> @torch.library.custom_op("mylib::numpy_sin", mutates_args=()) >>> def numpy_sin(x: Tensor) -> Tensor: >>> x_np = x.cpu().numpy() >>> y_np = np.sin(x_np) >>> return torch.from_numpy(y_np).to(device=x.device) >>> >>> def setup_context(ctx, inputs, output) -> Tensor: >>> x, = inputs >>> ctx.save_for_backward(x) >>> >>> def backward(ctx, grad): >>> x, = ctx.saved_tensors >>> return grad * x.cos() >>> >>> torch.library.register_autograd( ...

This API may be used as a decorator (see examples). In order for an operator to work with :func:`torch.vmap`, you may need to register a vmap implementation in the following signature: ``vmap_func(info, in_dims: Tuple[Optional[int]], *args, **kwargs)``, where ``*args`` and ``**kwargs`` are the arguments and kwargs for ``op``. We do not support kwarg-only Tensor args. It specifies how do we compute the batched version of ``op`` given inputs with an additional dimension (specified by ``in_dims``). For each arg in ``args``, ``in_dims`` has a corresponding ``Optional[int]``. It is ``None`` if the arg is not a Tensor or if the arg is not being vmapped over, otherwise, it is an integer specifying what dimension of the Tensor is being vmapped over. ``info`` is a collection of additional metadata that may be helpful: ``info.batch_size`` specifies the size of the dimension being vmapped over, while ``info.randomness`` is the ``randomness`` option that was passed to :func:`torch.vmap`. The return of the function ``func`` is a tuple of ``(output, out_dims)``. Similar to ``in_dims``, ``out_dims`` should be of the same structure as ``output`` and contain one ``out_dim`` per output that specifies if the output has the vmapped dimension and what index it is in. Examples: >>> import torch >>> import numpy as np >>> from torch import Tensor >>> from typing import Tuple >>> >>> def to_numpy(tensor): >>> return tensor.cpu().numpy() >>> >>> lib = torch.library.Library("mylib", "FRAGMENT") >>> @torch.library.custom_op("mylib::numpy_cube", mutates_args=()) >>> def numpy_cube(x: Tensor) -> Tuple[Tensor, Tensor]: >>> x_np = to_numpy(x) >>> dx = torch.tensor(3 * x_np ** 2, device=x.device) >>> return torch.tensor(x_np ** 3, device=x.device), dx >>> >>> def numpy_cube_vmap(info, in_dims, x): >>> result = numpy_cube(x) >>> return result, (in_dims[0], in_dims[0]) >>> >>> torch.library.register_vmap(numpy_cube, numpy_cube_vmap) >>> >>> x = torch.randn(3) >>> torch.vmap(numpy_cube)(x) >>> >>> @torch.library.custom_op("mylib::numpy_mul", mutates_args=()) >>> def numpy_mul(x: Tensor, y: Tensor) -> Tensor: >>> return torch.tensor(to_numpy(x) * to_numpy(y), device=x.device) >>> >>> @torch.library.register_vmap("mylib::numpy_mul") >>> def numpy_mul_vmap(info, in_dims, x, y): >>> x_bdim, y_bdim = in_dims >>> x = x.movedim(x_bdim, -1) if x_bdim is not None else x.unsqueeze(-1) >>> y = y.movedim(y_bdim, -1) if y_bdim is not None else y.unsqueeze(-1) >>> result = x * y >>> result = result.movedim(-1, 0) >>> return result, 0 >>> >>> >>> x = torch.randn(3) >>> y = torch.randn(3) >>> torch.vmap(numpy_mul)(x, y) .. note:: The vmap function should aim to preserve the semantics of the entire custom operator. That is, ``grad(vmap(op))`` should be replaceable with a ``grad(map(op))``.

That is, when you use the torch.library/TORCH_LIBRARY APIs to create a custom op, you specified metadata (e.g. mutability info) about the custom op and these APIs require that the functions you pass them satisfy certain properties (e.g. no data pointer access in the fake/meta/abstract kernel) ``opcheck`` tests these metadata and properties. Concretely, we test the following: - test_schema: If the schema matches the implementation of the operator. For example: if the schema specifies a Tensor is mutated, then we check the implementation mutates the Tensor. If the schema specifies that we return a new Tensor, then we check that the implementation returns a new Tensor (instead of an existing one or a view of an existing one). - test_autograd_registration: If the operator supports training (autograd): we check that its autograd formula is registered via torch.library.register_autograd or a manual registration to one or more DispatchKey::Autograd keys. Any other DispatchKey-based registrations may lead to undefined behavior. - test_faketensor: If the operator has a FakeTensor kernel (and if it is correct). The FakeTensor kernel is necessary ( but not sufficient) for the operator to work with PyTorch compilation APIs (torch.compile/export/FX). We check that a FakeTensor kernel (also sometimes known as a meta kernel) was registered for the operator and that it is correct. This test takes the result of running the operator on real tensors and the result of running the operator on FakeTensors and checks that they have the same Tensor metadata (sizes/strides/dtype/device/etc). - test_aot_dispatch_dynamic: If the operator has correct behavior with PyTorch compilation APIs (torch.compile/export/FX). This checks that the outputs (and gradients, if applicable) are the same under eager-mode PyTorch and torch.compile. This test is a superset of ``test_faketensor`` and is an e2e test; other things it tests are that the operator supports functionalization and that the backward pass (if it exists) also supports FakeTensor and functionalization. For best results, please call ``opcheck`` multiple times with a representative set of inputs. If your operator supports autograd, please use ``opcheck`` with inputs with ``requires_grad = True``; if your operator supports multiple devices (e.g. CPU and CUDA), please use ``opcheck`` with inputs on all supported devices. Args: op: The operator. Must either be a function decorated with :func:`torch.library.custom_op` or an OpOverload/OpOverloadPacket found in torch.ops.* (e.g. torch.ops.aten.sin, torch.ops.mylib.foo) args: The args to the operator kwargs: The kwargs to the operator test_utils: Tests that we should run. Default: all of them. Example: ("test_schema", "test_faketensor") raise_exception: If we should raise an exception on the first error. If False, we will return a dict with information on if each test passed or not. .. warning:: opcheck and :func:`torch.autograd.gradcheck` test different things; opcheck tests if your usage of torch.library APIs is correct while :func:`torch.autograd.gradcheck` tests if your autograd formula is mathematically correct. Use both to test custom ops that support gradient computation.
