require 'lmdb' failed

[aks009]

Hi,

I installed torch with the command
TORCH_LUA_VERSION=LUA51 ./install.sh

The installation was successful. Then I installed lmdb by << sudo -E /usr/local/torch/install/bin/luarocks install lmdb.torch >>

on th>> prompt
th> require 'lmdb'
lua: parser.c:2059: parse_root: Assertion `lua_gettop(L) == top' failed.
Aborted (core dumped)

the same error appears when I run a training program
Inside luaopen_libcrnn
In init()
1
1
lua: parser.c:2059: parse_root: Assertion `lua_gettop(L) == top' failed.
Aborted (core dumped)

Can anybody please help me on this.. what am I missing.

Thanks,
Ashwini
