# Welcome to the PyTorch setup.py.
#
# Environment variables you are probably interested in:
#
# DEBUG
# build with -O0 and -g (debug symbols)
#
# REL_WITH_DEB_INFO
# build with optimizations and -g (debug symbols)
#
# MAX_JOBS
# maximum number of compile jobs we should use to compile your code
#
# USE_CUDA=0
# disables CUDA build
#
# CFLAGS
# flags to apply to both C and C++ files to be compiled (a quirk of setup.py
# which we have faithfully adhered to in our build system is that CFLAGS
# also applies to C++ files (unless CXXFLAGS is set), in contrast to the
# default behavior of autogoo and cmake build systems.)
#
# CC
# the C/C++ compiler to use
#
# Environment variables for feature toggles:
#
# USE_CUDNN=0
# disables the cuDNN build
#
# USE_FBGEMM=0
# disables the FBGEMM build
#
# USE_KINETO=0
# disables usage of libkineto library for profiling
#
# USE_NUMPY=0
# disables the NumPy build
#
# BUILD_TEST=0
# disables the test build
#
# USE_MKLDNN=0
# disables use of MKLDNN
#
# USE_MKLDNN_ACL
# enables use of Compute Library backend for MKLDNN on Arm;
# USE_MKLDNN must be explicitly enabled.
#
# MKLDNN_CPU_RUNTIME
# MKL-DNN threading mode: TBB or OMP (default)
#
# USE_STATIC_MKL
# Prefer to link with MKL statically - Unix only
# USE_ITT=0
# disable use of Intel(R) VTune Profiler's ITT functionality
#
# USE_NNPACK=0
# disables NNPACK build
#
# USE_QNNPACK=0
# disables QNNPACK build (quantized 8-bit operators)
#
# USE_DISTRIBUTED=0
# disables distributed (c10d, gloo, mpi, etc.) build
#
# USE_TENSORPIPE=0
# disables distributed Tensorpipe backend build
#
# USE_GLOO=0
# disables distributed gloo backend build
#
# USE_MPI=0
# disables distributed MPI backend build
#
# USE_SYSTEM_NCCL=0
# disables use of system-wide nccl (we will use our submoduled
# copy in third_party/nccl)
#
# BUILD_CAFFE2_OPS=0
# disable Caffe2 operators build
#
# BUILD_CAFFE2=0
# disable Caffe2 build
#
# USE_IBVERBS
# toggle features related to distributed support
#
# USE_OPENCV
# enables use of OpenCV for additional operators
#
# USE_OPENMP=0
# disables use of OpenMP for parallelization
#
# USE_FFMPEG
# enables use of ffmpeg for additional operators
#
# USE_LEVELDB
# enables use of LevelDB for storage
#
# USE_LMDB
# enables use of LMDB for storage
#
# BUILD_BINARY
# enables the additional binaries/ build
#
# ATEN_AVX512_256=TRUE
# ATen AVX2 kernels can use 32 ymm registers, instead of the default 16.
# This option can be used if AVX512 doesn't perform well on a machine.
# The FBGEMM library also uses AVX512_256 kernels on Xeon D processors,
# but it also has some (optimized) assembly code.
#
# PYTORCH_BUILD_VERSION
# PYTORCH_BUILD_NUMBER
# specify the version of PyTorch, rather than the hard-coded version
# in this file; used when we're building binaries for distribution
#
# TORCH_CUDA_ARCH_LIST
# specify which CUDA architectures to build for.
# ie `TORCH_CUDA_ARCH_LIST="6.0;7.0"`
# These are not CUDA versions, instead, they specify what
# classes of NVIDIA hardware we should generate PTX for.
#
# PYTORCH_ROCM_ARCH
# specify which AMD GPU targets to build for.
# ie `PYTORCH_ROCM_ARCH="gfx900;gfx906"`
#
# ONNX_NAMESPACE
# specify a namespace for ONNX built here rather than the hard-coded
# one in this file; needed to build with other frameworks that share ONNX.
#
# BLAS
# BLAS to be used by Caffe2. Can be MKL, Eigen, ATLAS, FlexiBLAS, or OpenBLAS. If set
# then the build will fail if the requested BLAS is not found, otherwise
# the BLAS will be chosen based on what is found on your system.
#
# MKL_THREADING
# MKL threading mode: SEQ, TBB or OMP (default)
#
# USE_REDIS
# Whether to use Redis for distributed workflows (Linux only)
#
# USE_ZSTD
# Enables use of ZSTD, if the libraries are found
#
# Environment variables we respect (these environment variables are
# conventional and are often understood/set by other software.)
#
# CUDA_HOME (Linux/OS X)
# CUDA_PATH (Windows)
# specify where CUDA is installed; usually /usr/local/cuda or
# /usr/local/cuda-x.y
# CUDAHOSTCXX
# specify a different compiler than the system one to use as the CUDA
# host compiler for nvcc.
#
# CUDA_NVCC_EXECUTABLE
# Specify a NVCC to use. This is used in our CI to point to a cached nvcc
#
# CUDNN_LIB_DIR
# CUDNN_INCLUDE_DIR
# CUDNN_LIBRARY
# specify where cuDNN is installed
#
# MIOPEN_LIB_DIR
# MIOPEN_INCLUDE_DIR
# MIOPEN_LIBRARY
# specify where MIOpen is installed
#
# NCCL_ROOT
# NCCL_LIB_DIR
# NCCL_INCLUDE_DIR
# specify where nccl is installed
#
# NVTOOLSEXT_PATH (Windows only)
# specify where nvtoolsext is installed
#
# ACL_ROOT_DIR
# specify where Compute Library is installed
#
# LIBRARY_PATH
# LD_LIBRARY_PATH
# we will search for libraries in these paths
#
# ATEN_THREADING
# ATen parallel backend to use for intra- and inter-op parallelism
# possible values:
# OMP - use OpenMP for intra-op and native backend for inter-op tasks
# NATIVE - use native thread pool for both intra- and inter-op tasks
# TBB - using TBB for intra- and native thread pool for inter-op parallelism
#
# USE_TBB
# enable TBB support
#
# USE_SYSTEM_TBB
# Use system-provided Intel TBB.
#
# USE_SYSTEM_LIBS (work in progress)
# Use system-provided libraries to satisfy the build dependencies.
# When turned on, the following cmake variables will be toggled as well:
# USE_SYSTEM_CPUINFO=ON USE_SYSTEM_SLEEF=ON BUILD_CUSTOM_PROTOBUF=OFF
# This future is needed to print Python2 EOL message
