I have this issue while running th preprocess.lua -config config-preprocess

How do i fix it ?

Try running the following
#for Torch with Lua 5.3:
import os
os.environ['LUA_PATH'] = '/root/.luarocks/share/lua/5.3/?.lua;/root/.luarocks/share/lua/5.3/?/init.lua;/root/torch/install/share/lua/5.3/?.lua;/root/torch/install/share/lua/5.3/?/init.lua;/root/torch/install/lib/lua/5.3/?.lua;/root/torch/install/lib/lua/5.3/?/init.lua;./?.lua;./?/init.lua'
os.environ['LUA_CPATH'] ='/root/.luarocks/lib/lua/5.3/?.so;/root/torch/install/lib/lua/5.3/?.so;/root/torch/install/lib/lua/5.3/loadall.so;./?.so'
os.environ['PATH'] += ':/root/torch/install/bin'

if 'LD_LIBRARY_PATH' not in os.environ.keys():
os.environ['LD_LIBRARY_PATH'] = ''
else:
os.environ['LD_LIBRARY_PATH'] += ':'
os.environ['LD_LIBRARY_PATH'] +='/root/torch/install/lib'

if 'DYLD_LIBRARY_PATH' not in os.environ.keys():
os.environ['DYLD_LIBRARY_PATH'] = ''
else:
os.environ['DYLD_LIBRARY_PATH'] += ':'
os.environ['DYLD_LIBRARY_PATH'] +='/root/torch/install/lib'

if 'LUA_CPATH' not in os.environ.keys():
os.environ['LUA_CPATH'] = ''
else:
os.environ['LUA_CPATH'] += ';'
os.environ['LUA_CPATH'] += '/root/torch/install/lib/?.so'

$luarocks install tds

and then your command
