Torch7 学习笔记[3] --option setting

参考～/torch/pkg/torch/doc/cmdline.md

--setting the opt
local M = { }

function M.parse(arg)
   local cmd = torch.CmdLine()
   cmd:text()
   cmd:text('Torch-7 net Training demo')
   cmd:text()
   cmd:text('Options:')
   cmd:option('-manualSeed', 0,          'Manually set RNG seed')
   cmd:option('-resume',          'none',        'Resume from the latest checkpoint in this directory')
   cmd:option('-type',       'float',         'float -> cpu; cuda -> gpu')
   cmd:option('-save',            'checkpoints', 'Directory in which to save checkpoints')
   cmd:option('-max_epoch',         0,       'Number of total epochs to run')
   local opt = cmd:parse(arg or {})
   return opt
end
return M

需要解释cmd:option(‘-manualSeed’, 0, ‘Manually set RNG seed’)这个函数：option(name, default, help)
cmd:option(‘-A’,B,’C’) A代表参数名称，B表示默认值，C表示提示。
该类下其他函数用法：

torch.CmdLine:log(filename,parameter_table)  --write the parameter_table to the filename
torch.CmdLine:parse(arg) --返回参数表，由option定义
torch.CmdLine:silent()  --只会保留向文件中写入功能，其他输出silent
