CentOS 7 9 從原始碼安裝PyTorch

系統自帶的4.8.5的gcc不滿足編譯要求，所以需要公升級一下。我直接從原始碼編譯安裝gcc 7.5.0

tar xzf gcc-7.5.0.tar.gz

cd gcc-7.5.0/
mkdir build &&
cd build
../configure --enable-languages=c,c++ --disable-multilib
make -j$(nproc)
sudo
make
install

export path=

"/usr/local/bin:$path"
export ld_library_path=
"/usr/local/lib64:$ld_library_path"
export ld_run_path=
"/usr/local/lib64:$ld_run_path"

source ~/.bashrc

gcc --version

conda create --name torch

conda activate torch

conda install numpy ninja pyyaml mkl mkl-include setuptools cmake cffi typing_extensions future six requests dataclasses

conda install -c pytorch magma-cuda102 # 根據cuda版本改一下
git clone --recursive 
cd pytorch
# 編譯1.7.0版本
git checkout v1.7.0
git submodule sync
git submodule update --init --recursive
# 編譯
export cmake_prefix_path=$
python setup.py install

conda list

git clone 

cd vision 
mkdir build &&
cd build
# 編譯和pytorch v1.7.0對應的v0.8.0版本
git checkout v0.8.0
python setup.py install

conda list

注意，如果中間編譯失敗了，最好把編譯用的build資料夾刪除後重新編譯。
