qlua: undefined symbol

[xyxxyx]

I train the DQN and get a trained model successfully. But when I test the model using the test_gpu.lua, I get the followed error:

qlua: symbol lookup error: /home/xx/ torch/install/bin/../lib/libqlua.so: undefined symbol : _ZH6QMutex12lockInternalEv.
@kuz Can you give me some advice? Thank you!
