#ifdef TORCH_ASSERT_NO_OPERATORS
#error This change adds a dependency on native_functions.yaml,            \
  meaning the file will need to be re-compiled every time an operator     \
  is changed or added. Consider if your change would be better placed in  \
  another file, or if a more specific header might achieve the same goal. \

#error This change adds a dependency on all pytorch operators, meaning the     \
  file will need to be re-compiled every time an operator is changed or added. \
  Consider including a specific operator from <ATen/ops/{my_operator}.h> and   \
  see NOTE [TORCH_ASSERT_ONLY_METHOD_OPERATORS].

// NOTE: [TORCH_ASSERT_ONLY_METHOD_OPERATORS]
//
// In ATen, certain generated headers files include the definitions of
// every single operator in PyTorch. Unfortunately this means every
// time an operator signature is updated or changed in
// native_functions.yaml, you (and every other PyTorch developer) need
// to recompile every source file that includes any of these headers.
//
// To break up these header dependencies, and improve incremental
// build times for all PyTorch developers. These headers are split
// into per-operator headers in the `ATen/ops` folder. This limits
// incremental builds to only changes to methods of `Tensor`, or files
// that use the specific operator being changed. With `at::sum` as an
// example, you should include
//
//   <ATen/ops/sum.h>               // instead of ATen/Functions.h
//   <ATen/ops/sum_native.h>        // instead of ATen/NativeFunctions.h
//   <ATen/ops/sum_ops.h>           // instead of ATen/Operators.h
//   <ATen/ops/sum_cpu_dispatch.h>  // instead of ATen/CPUFunctions.h
//
// However, even if you're careful to use this in your own code.
// `Functions.h` might be included indirectly through another header
// without you realising. To avoid this, you can add
//
//   #define TORCH_ASSERT_ONLY_METHOD_OPERATORS
//
// to the top of your source file. This way any time the non-specific
// headers are included, the compiler will error out.
//
// Also, be aware that `ops` are not available in all build
// configurations (namely fb-internal) so you must guard these
// includes with `#ifdef AT_PER_OPERATOR_HEADERS`. e.g.
//
//   #ifndef AT_PER_OPERATOR_HEADERS
//   #include <ATen/Functions.h>
//   #else
//   #include <ATen/ops/sum.h>
//   #endif
