setup.py

# 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, in contrast to the default behavior of autogoo
#     and cmake build systems.)
#
#   CC
#     the C/C++ compiler to use (NB: the CXX flag has no effect for distutils
#     compiles, because distutils always uses CC to compile, even for C++
#     files.
#
# Environment variables for feature toggles:
#
#   USE_CUDNN=0
#     disables the cuDNN build
#
#   USE_FBGEMM=0
#     disables the FBGEMM build
#
#   BUILD_TEST=0
#     disables the test build
#
#   USE_MIOPEN=0
#     disables the MIOpen build
#
#   USE_MKLDNN=0
#     disables use of MKLDNN
#
#   MKLDNN_THREADING
#     MKL-DNN threading mode (https://github.com/intel/mkl-dnn/)
#
#   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_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
#
#   USE_GLOO_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
#
#   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.
#
#   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, 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_SEQ=1
#     chooses a sequential version of MKL library (in case of BLAS=MKL)
#
#   USE_FBGEMM
#     Enables use of FBGEMM
#
#   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_DIR
#   NCCL_LIB_DIR
#   NCCL_INCLUDE_DIR
#     specify where nccl is installed
#
#   NVTOOLSEXT_PATH (Windows only)
#     specify where nvtoolsext is installed
#
#   LIBRARY_PATH
#   LD_LIBRARY_PATH
#     we will search for libraries in these paths
#
#   PARALLEL_BACKEND
#     parallel backend to use for intra- and inter-op parallelism
#     possible values:
#       OPENMP - use OpenMP for intra-op and native backend for inter-op tasks
#       NATIVE - use native thread pool for both intra- and inter-op tasks
#
#   USE_TBB
#      use TBB for parallelization
