下载torch安装包:
git clone https://github.com/torch/distro.git torch --recursive
安装依赖库:
cd torch/
sudo bash install-deps
安装好后会提示:
Torch7’s dependencies have been installed
安装torch:
sudo ./install.sh
安装到最后会提示是否将torch安装路径加入~/.bashrc文件中:
Do you want to automatically prepend the Torch install location
to PATH and LD_LIBRARY_PATH in your /home/qinghua/.bashrc? (yes/no)
选择自动添加,输入yes,按enter键即可.
终端输入th命令进入torch:
th
这时提示错误:
/usr/local/bin/th: 行 3: /home/qinghua/program/torch_src/torch/install/bin/luajit: 没有那个文件或目录
这是因为系统找不到torch安装路径,这时候需要更新环境变量,即运行:
source ~/.bashrc
重新输入th即可
th
大概出现这样的画面
