[Nvidia发布了编译好的pytorch版本，可自行百度点我，最好不要自己编译]
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 <torch/csrc/cuda/nccl.h>
# Comment torch::cuda::nccl::reduce
