Could not find network file

when I run this command:

sudo ./test_gpu breakout DQN3_0_1_breakout_FULL_Y.t7

the output is:

I have trained the model and the network file exists in "dqn" directory. can somebody tell me what is wrong?

Update:

I think the problem was about the network file. The training process should be completed before using it.

on training, you can save before the file before it the train is end.
edit run_gpu / run_cpu end edit the save_freq value to 5000 or so, then you have the file to play with.
