Jetson TX2 编译 Pytorch (Wheel)

参考 https://gist.github.com/dusty-nv/ef2b372301c00c0a9d3203e42fd83426

1. 按照注释内容修改源码

2. 修改 -d 参数 

sudo python setup.py bdist_wheel -d [the path where to save the wheel file]

 3. 执行以下命令

### before you build pytorch modify the following files

#./pytorch/CMakeList.txt
#   > CmakeLists.txt : Change NCCL to 'OFF' on line 97
#./pytorch/setup.py
#   > setup.py: Add USE_NCCL = False below line 198
#./pytorch/tools/setup_helpers/nccl.py
#   > nccl.py : Change USE_SYSTEM_NCCL to 'False'
#               Change NCCL to 'False'
#./pytorch/torch/csrc/cuda/nccl.h
#   > nccl.h : Comment self-include on line 8
#              Comment entire code:
#		//void throw_nccl_error(ncclResult_t status);
#
#		//static inline void NCCL_CHECK(ncclResult_t status) {
#		//  if (status != ncclSuccess) {
#		//    throw_nccl_error(status);
#		//  }
#		//}
#./torch/csrc/distributed/c10d/ddp.cpp
#   > ddp.cpp : Comment #include 
#               Comment torch::cuda::nccl::reduce
