# Defines derivative formulas and Python signatures of methods on Variable
|
|
#
|
|
# Note about possibly confusing nomenclature: An 'output gradient' is the
|
|
# gradient of an output of a forward function. Output gradients are used as
|
|
# the inputs to backward functions. `grads` is a vector of output gradients,
|
|
# and `grad == grads[0]`, in all the derivative formulas in this file.
|
|
# An 'input gradient' is the gradient of an input to a forward function.
|
|
# Input gradients are the outputs of backward functions, corresponding to the
|
|
# input names included in the derivative formulas defined in this file.
|
|
# Also, every time we talk computing "gradient" we actually mean computing
|
|
# the vector jacobian product using the given 'output gradient' as the vector.
|
|
#
|
|
# Each entry consists of:
|
|
# - A 'name', which specifies the ATen name of the function you
|
|
# are defining derivatives for, and an argument specification.
|
|
# - An optional 'dispatch' entry which can be used to specify
|
|
# per-autograd dispatch key derivatives. If this entry is not
|
|
# specified, then the gradient entries will be taken as the
|
|
# default gradients (i.e. registered for every backward dispatch
|
|
# key). (see _test_autograd_multiple_dispatch for an example
|
|
# of how to register separate derivates for different dispatch keys).
|
|
# The list of allowed dispatch keys (in addition to 'Default' which
|
|
# represents the Autograd alias key) is torchgen/model.py:AUTOGRAD_KEYS.
|
|
# - One or more gradients entries, mapping differentiable input
|
|
# names to a formula specifying how to compute its gradient.
|
|
# Note that a single gradient entry can specify the gradient
|
|
# formula for multiple input names, by specifying a key
|
|
# "input1, input2" (see atan2 for an example).
|
|
# - An argument can be flagged as 'non_differentiable'.
|
|
# - Optional entry with key 'output_differentiability' and value a list of the
|
|
# same length as the number of outputs from the forward function. The list
|
|
# should contain only booleans, specifying whether each of the output Tensor
|
|
# is differentiable.
|
|
# If it is not specified for a function that returns multiple elements but
|
|
# uses `grad` instead of `grads[idx]`, then all but the first output will
|
|
# be marked as non-differentiable.
|
|
# If None of the output is differentiable, you can also add the function
|
|
# name to `gen_variable_type.py`'s `DONT_REQUIRE_DERIVATIVE` list.
|
|
#
|
|
# There are two cases for Tensor and TensorList arguments here:
|
|
# - If that argument is differentiable, in the sense that a gradient with respect
|
|
# to that argument could exist. You should either:
|
|
# - Specify the formula for that gradient
|
|
# - Specify not_implemented("function_name") as a formula to say that this is not
|
|
# implemented yet (but might be in the future and the user can request that on an issue)
|
|
# - If that argument is not differentiable, because it is not a floating point dtype or the
|
|
# function is not differentiable with respect to that argument for
|
|
# example. You should either:
|
|
# - Do not specify any formula for this argument
|
|
# - Specify explicitly that this argument is "non_differentiable". Note that in this case,
|
|
# we trust you that this argument will never have requires_grad=True and it will be silently
|
|
# ignored if it does.
|
|
#
|
|
# If a function has out-of-place and in-place variants, then the derivative
|
|
# definition for the in-place variant is optional. It will default to the
|
|
# definition for the out-of-place variant. Note that _out variants are never
|
|
# differentiable.
|
|
#
|
|
# Gradient expressions are standard C++ expressions operating on ATen
|
|
# variables. In a gradient expression, the following variables/functions
|
|
# are in scope:
|
|
#
|
|
# - 'grad', the gradient of the output (often spelled grad_output
|
|
# in Python) which we are going to left-multiply.
|
|
#
|
|
# When a function returns multiple *differentiable* outputs,
|
|
# you can refer to the gradients of each outputs using 'grads',
|
|
# e.g., 'grads[0]', 'grads[1]'.
|
|
#
|
|
# When a function returns multiple *differentiable* outputs that
|
|
# are named, you can refer to the gradients of each outputs using
|
|
# 'grad_{name}', e.g., 'grad_x', 'grad_y'.
|
|
#
|
|
# When a function returns *one* differentiable output (the
|
|
# first output) and some more nondifferentiable outputs,
|
|
# you MUST refer to the gradient of the differentiable output with
|
|
# 'grad' (this case is special-cased in our code generation).
|
|
#
|
|
# Note that the number of differentibale outputs can be modified by the
|
|
# 'output_differentiability' entry (see above).
|
|
#
|
|
# Across a differentiable function's derivatives set, it is not
|
|
# permitted to mix the use of "grad", "grads", and
|
|
# "grad_{name}". You must be consistent for that differentiable
|
|
# function.
|
|
#
|
|
# - Any of the input arguments, tensor or non-tensor, including
|
|
# argument names that only appear in Declarations.yaml, e.g. 'output'.
|
|
#
|
|
# - 'result', representing the result of evaluating the forward
|
|
# expression for ATen native function declarations. If the forward
|
|
# expression outputs a tuple, use 'resultX' instead to access the
|
|
# X-th entry
|
|
#
|
|
# - 'grad_input_mask', a std::array<bool, n>, specifies which input
|
|
# gradients are actually needed. For example, in the entry
|
|
# `input0, input1: foo(grad_input_mask)`, `grad_input_mask` is a size
|
|
# two array, where `grad_input_mask[0]` is true if `input0` requires
|
|
# grad, and `grad_input_mask[1]` is true if `input1` requires grad.
|
|
#
|
|
# (NB: if your function computes gradient for a list of tensors,
|
|
# the `grad_input_mask` will only have a single entry for the list
|
|
# specifying if either zero or at least one tensor from the list requires
|
|
# grad. If we want to support more fine-grained signalling,
|
|
# we'll need some alternate variable which is not a std::array)
|
|
#
|
|
# - 'retain_variables', a bool which is true if a user has specified
|
|
# that saved variables should be retained in case the backwards is
|
|
# run again later. This allows an optimization where we can
|
|
# destroy saved buffers if we know variables are not going to be retained,
|
|
# e.g., it is used by _cudnn_rnn
|
|
#
|
|
# - `wrap_opt_if`, is a 2-argument function that accepts a tensor
|
|
# variable and a boolean condition that dictates whether to save that
|
|
# variable in a graph. The result of this function is `c10::optional<Tensor>`,
|
|
# and it is `c10::nullopt` when the condition evalutes to `false`,
|
|
# otherwise it is the variable wrapped in `c10::optional<Tensor>`.
|
|
# For example, wrap_opt_if(var_0, grad_input_mask[1] || grad_input_mask[2])
|
|
# would mean that `var_0` is saved as long as the second (grad_input_mask[1])
|
|
# or the third (grad_input_mask[2]) argument requires gradients.
|
|
# Another interpretation of this expression would read as `var_0` is needed
|
|
# in the backward computation of the second or the third argument.
|
|
# NOTE: the usage of `var_i.requires_grad()` in the conditional expression
|
|
# is not supported, use `grad_input_mask[i]` instead.
|
|
# NOTE: `wrap_opt_if` could be used to prevent saving redundant variables
|
|
# with multi-output backward formulas.
|
|
# See https://github.com/pytorch/pytorch/issues/97575 for more details
|
|
# on the issue.
|
|
#
|
|
# If you need a complex expression, e.g., with local variables,
|
|
# write a _backward function in torch/csrc/autograd/FunctionsManual.cpp
|
|
# and invoke it from here. By the way, go read
|
|
# https://github.com/zdevito/ATen/issues/163; this describes an
|
|
# important hazard that occurs when porting backwards from Python to C++
|
|
#
|
|
# Double backwards gradient expressions can be somewhat confusing;
|
|
# the most important thing to remember is: (1) you need to define a
|
|
# derivative formula for every input, including inputs named things
|
|
# like 'grad_output', and (2) the gradient to multiply with is always
|
|
# called 'grad' (even though it really is a grad-grad).
|
|
#
|
|
# You can also add forward derivative definition by defining a formula for
|
|
# a returned value (in general "result" if the name is not specified). This
|
|
# formula works the same way as the backward one and advanced implementations
|
|
# should also be placed in the FunctionsManual file.
|
|
# This formula should compute a single Jacobian vector product using the (primal)
|
|
# value of the argument "foo_p", its forward grad "foo_t" and the result of the
|
|
# function as "result".
|
|
# Note that the forward derivative can be automatically generated in two cases:
|
|
# - if your function is linear (NOT affine or multi-linear), then you can
|
|
# specify so by just using the string "auto_linear" for the formula.
|
|
# - if your function is applied element wise (and has a single input), you
|
|
# can specify so by just using the string "auto_element_wise" for the formula.
|
|
#
|
|
# Note that to avoid unpacking overhead, functions taking TensorList as inputs
|
|
# will always have their forward grad formula called. This function is responsible
|
|
# to check if any computation is needed and should return an undefined Tensor when
|
|
# there is nothing to do. You can check "cat_forward" for a full example.
|
|
#
|
|
# NB: There are a number of gradient definitions in here which are bogus
|
|
# (implemented using zeros_like). These gradients are (hopefully) not
|
|
# used by our frontend. You MUST check the frontend code; search for
|
|
# OpName.apply to see if it's still using a legacy Python style API.
|
|
#
|
|
# Note: Returning views.
|
|
# The following cases exist:
|
|
# - If a function returns no view, it can have arbitrary outputs.
|
|
# - If a function return at least one Tensor that is a differentiable view
|
|
# of one of its input:
|
|
# - If there is only one differentiable output, this Tensor is marked as a
|
|
# differentiable view. (alias or transpose for example)
|
|
# - If there are more than one differentiable output, by default all the views are
|
|
# marked as differentiable views and created with allow_rebase_history=false.
|
|
# Meaning that any inplace operation on it will raise an error. (unbind for example)
|
|
#
|
|
# Notes about undefined output gradients:
|
|
# All backward functions must support all combinations of undefined output
|
|
# gradient Tensors, where `grad[i].defined() == false`. Depending on the
|
|
# number of input and output grads your derivative formula uses, code
|
|
# generation may automatically add some level of undefined grad support,
|
|
# according to these three cases:
|
|
#
|
|
# * 1 input grad and 1 output grad:
|
|
# Complete undefined grad support is automatically added, so you
|
|
# shouldn't have to think about it, unless there is a bug in the code
|
|
# generation.
|
|
#
|
|
# * 1 input grad and multiple output grads:
|
|
# Undefined grad support is automatically added ONLY in the case where
|
|
# all output grads are undefined. You will have to add explicit support
|
|
# for cases where a subset of output grads is undefined.
|
|
#
|
|
# * multiple input grads:
|
|
# No automatic support, so you will need to add it.
|
|
#
|
|
# If your derivative formula uses more than one output grad, it is usually
|
|
# preferable to add undefined grad support in the backward function itself
|
|
# (if you're using one), rather than in the derivative formula in this file.
|
|
#
|
|
# Undefined Tensors are created with the default constructor `at::Tensor()`.
|
|
# It is an efficient way to represent a Tensor filled with zeros because
|
|
# the Tensor holds no sizing information and no Storage data is allocated.
|
|
# But consequentially, Tensor operations cannot be performed on them.
|
|
# Therefore, your backward function should treat an undefined output grad as
|
|
# a zero, and it needs to be a special case.
|
|
#
|
|
# If all output grads are undefined, then it should be correct for the
|
|
# backward function to return undefined input grads. Since we use the chain
|
|
# rule, output grads equal to zero should result in input grads equal to zero,
|
|
# unless there is some rare special case.
|
|
#
|
|
# If a subset of output grads is undefined, then it may be acceptable for
|
|
# the backward function to return undefined input grads--it depends on the
|
|
# specific function, so you'll have to determine that yourself. If returning
|
|
# an undefined Tensor is correct for a given input grad, it is also logically
|
|
# correct to return a defined grad full of zeros, but that would not be
|
|
# preferable since it would be less efficient.
|
|
#
|
|
# NB: The parameter names here MUST be consistent with the parameter names
|
|
# in native_functions.yaml
