hi guys, I'm Super nb with ubuntu(my first time) and trying to play Deepmind's ataribreak-out by following https://github.com/kuz/DeepMind-Atari-Deep-Q-Learner

I'm under ubuntu 16.04.1 LTS with GTX Titan xp

When I wright ./install_dependencies.sh, it stops with these mentions

-- Installing: /home/ksj/atari/dqn/torch/bin/luarocks-admin
/home/ksj/atari/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory

=> Torch7 has been installed successfully

Installing nngraph ...
/home/ksj/atari/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
Error. Exiting.

I tried to download libreadline.so.7 by using apt-cache and apt-get
but there is no .so.7 only 6 or lower versions.

How can I get libreadline.so.7

I would try apt install luajit from official repos, that would not require libreadline.so.7
Also you can do something similar with torch, just I don't know the name of the package (but you can find it in install_dependencies.sh)

Hello, I meet with the same question when I was setting up the dqn, how did you tackle the ../torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory issue?
