# Note [Adding an alias]
# To add an alias do the following:
#
# 1) Copy the original functions native_functions.yaml entry, but replace the
#      original function's name with their own and delete any dispatch
#      keys for the aliases. Specifying a dispatch key will prevent
#      autograd from recording the operations the alias performs, which
#      will stop it from "inheriting" the original operation's autograd behavior.
# 2) Implement the corresponding functions and have them redispatch to the
#      original function.
# 3) Add entries for the alias (and original function, if needed) to
#      aten/src/ATen/core/interned_strings.h
#      (This may require removing an entry from ATen/core/aten_interned_strings.h.)
# 4) Add docstrings to the new function that reference the original function,
#      and document the method as usual (if it exists.)
#    (See torch/_torch_docs.py and docs/source/torch.rst if adding a function,
#     torch/_tensor_docs.py and docs/source/tensors.rst if adding a method,
#     or module-specific doc bindings (like torch/linalg/__init__.py) if
#     adding an alias in a namespace.)
# 5) Update torch/overrides.py consistent with the original function.
# 6) Update the alias_map in torch/csrc/jit/passes/normalize_ops.cpp.
# 7) Add entries to test/test_op_aliases.py's "alias_infos"
#
# See torch.absolute, an alias for torch.abs, as an example.

# NOTE [ grid_sampler Native Functions ]
# `grid_sampler` does all the shape checking and then dispatches to one of
# `cudnn_grid_sampler`, `grid_sampler_2d`, or `grid_sampler_3d`, each of which
# has the corresponding backward defined as native functions as well. Therefore,
# in these functions and their backwards, no more shape checking is done.
#
# There is also _grid_sampler_2d_backward_cpu_fallback which is an
# implementation detail of grid_sampler_2d and is only exposed here for testing
# purposes.
#
# Additionally, arguments `padding_mode` and `interpolation_mode` are cast to
# enums defined in `native/GridSampler.h`. `cudnn_grid_sampler` doesn't take in
# `interpolation_mode` because it only supports Bilinear interpolation mode.
# Nor does it take in `align_corners` because it only supports the mode
# `align_corners = True`.

# in the original tensor will also be updated. However, the new behavior is that
# those metadata changes to the detached tensor will not update the original tensor
# anymore, and in the `detach()` function we need to set `allow_tensor_metadata_change_`
# to false to make such changes explicitly illegal, in order to prevent users from

# NOTE [ Sparse: autograd and API ]
#
#
# Sparse Tensor Constructors
# ~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# The API entry points to sparse tensor construction should be
# `sparse_coo tensor` and `_sparse_coo_tensor_unsafe`. Depending on whether the
# indices and values tensors are given, they eventually dispatch to either
# `sparse_coo_tensor_with_dims` or `sparse_coo_tensor_with_dims_and_tensors`.
#
# The autograd support for ctor is implement on `sparse_coo_tensor_with_dims_and_tensors`.
#
# The API methods `sparse_coo tensor` and `_sparse_coo_tensor_unsafe`
# **must not** have specific type dispatches because otherwise codegen will
# consider them as abstract methods (see Note [Abstract ATen methods]), dispatch
# using **Tensor** type, and thus lose autograd tracking on the actual method
# they dispatch to, e.g., `sparse_coo_tensor_with_dims_and_tensors`.
#
#
# Sparse Methods API Design
# ~~~~~~~~~~~~~~~~~~~~~~~~~
#
# Goals: 1. Flexible API for users to write custom sparse ops
#        2. ctor and member accessor with autograd support
#
# To achieve 1, we need to provide a set of *dangerous* APIs (dangerous in the
# sense that misusing them will break sparse tensor invariant and may out in
# unexpected behavior, e.g., crash). These methods are all prefixed with
# underscore "_" to indicate that they should be used with care. We provide:
#
#   + `_indices()`: returns the *raw* indices within the sparse tensor (not just
#                   sharing storage). Any inplace operation will change the
#                   actual indices, including t_, set_, as_strided_, resize_,
#                   etc.
#   + `_values()`: returns the *raw* values within the sparse tensor. Similar
#                  semantics as `_indices()`
#   + `_nnz()`: returns the number of non-zero entries. This will always be
#               determined by the shapes of indices and values.
#   + `_coalesced_(bool)`: inplace sets whether the tensor is coalesced, and
#                          returns itself.
#
# These methods are very useful in writing new operations, e.g., a custom
# autograd Function.
#
# We also provide other public *safe* APIs:
#   + `indices()`: returns a **view** of the indices tensor if the sparse tensor
#                  is **coalesced**.
#   + `values()`: returns a **view** of the values tensor if the containing
#                 sparse tensor is **coalesced**.
#   + `sparse_dim()`: number of sparse dimensions
#   + `dense_dim()`: number of dense dimensions
#   + `is_coalesced()`: whether the sparse tensor is coalesced
#
# `_indices()` and `_values()` should returns the raw indices and values dense
# tensors within a sparse tensor. They can be quite unsafe with inplace
# operations like `t_()`, and exposes uncoalesced indices and values. The public
# recommended API is `indices()` and `values()`, both of which first check that
# the tensor is coalesced and return views on those tensors.
#
#
# Autograd Support
# ~~~~~~~~~~~~~~~~
#
# Autograd is supported on `values()` and sparse tensor ctor with indices and
# values tensors. E.g., `torch.sparse_coo_tensor(i, v).values().sum()` is
# differentiable w.r.t. `v`.
#
# NB: The `values()` and `_values()` operators are special in that they are
# layout-aware, i.e., the output depends not just on the data it represents, but
# also on the input layout details (in this case, the `indices` tensor). See
# NOTE [ as_strided Backward and layout-aware/agnostic autograd ] in Functions.cpp
# for discussion on layout-aware vs layout-agnostic autograd. Since PyTorch ops
# operate in the layout-agnostic mode, similar to `as_strided`, backward of
# these two operators need to consider them in a layout-agnostic way:
#   + `values()`:
#     Input is coalesced.
#     We just pretend having `input.indices()` as an additional argument
#     `input_indices`, then forward is similar to
#     `input.to(kStrided).index_select(input_indices)` regardless of the layout.
#     Note that `values()` normally is layout-aware even if we constrain
#     ourselves on sparse inputs since it may include all zeros values entries
#     as "present" entries.
#   + `_values()`:
#     Input may be uncoalesced.
#     It is not straightforward to construct a layout-agnostic version because
#     duplicate indices entries may exist and additional parameterization is
#     needed to distribute the value into different values entries. Furthermore,
#     this op is intended to provide ways to write custom sparse ops, rather
#     than being used in autograd graph, so it is marked as *non-differentiable*
#     in derivatives.yaml.
#
# Before reading the following, see NOTE [ Autograd Variable Views ] in
# variable.h for details on views that are tracked by autograd, and views that
# are not.
#
# Moreover, these methods return tensors that share storage with inputs, so we
# mark these methods as view ops to support autograd history tracking.
# The sparse tensor ctor output should technically be view of both input indices
# and values tensors, but currently we only support setting as view of a single
# Variable, so it is only view of the values tensor.
# TODO: clone indices in sparse tensor ctor.
#
# For other methods that return outputs that share storage with inputs, i.e.,
# `indices()` and `_indices()`. We mark their outputs as non-differentiable, so
# the view relation is not tracked by autograd, but the version counter is still
# shared. In other words, their outputs are non-differentiable views of the
# sparse tensor.

# FIXME: would be nicer if TensorOptions was optional based; not adding default arguments for options given
# the default would never make sense.

# What's a thnn_conv_ versus a slow_conv_?
#
# Historically, we have inefficient implementations of convolutions
# coming from the THNN/THCUNN library.  These convolutions typically
# operated by computing the Toeplitz matrix and then doing a matrix
# multiply with the input; this is very memory inefficient!  However,
# occasionally, we really don't have anything better, so it's helpful
# to have these fallbacks when there is no more optimized implementation
# in cudnn or mkldnn, etc.  Both thnn_ and slow_ convolutions fall
# into this bucket.
#
# The difference between these two designations, is that thnn_ refers
# to a convolution that is still written in the "legacy" style; that is,
# C code in the THNN/ or THCUNN/ directory.  A slow_ convolution is
# one that is written in the native style: modern C++.  Algorithmically,
# these are the same thing, but we give them different prefixes to
# make the operational distinction clear.
