Won't work with Lua 5.2

[fmguler]

When trying with Lua 5.2 gives the error:

/torch/install/share/lua/5.2/protobuf/wire_format.lua:21: attempt to call global 'module' (a nil value)

I guess the module keyword is removed in Lua 5.2

FYI, if you use the compatibility mode in Lua 5.2, you can still use the module keyword.
