Can it train on the server? No GUI.

I've been looking into the same thing, also tried to Dockerize it. I've made some progress with using Xvfb for headless video, but so far no luck with getting rid of the audio.

` apt-get intall -y xvfb

Xvfb :0 -screen 0 800x600x16 +extension RANDR &

export DISPLAY=:0

./mame `

Thanks. When I run mame. output tips: ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: Permission denied It can't continue.

"Permission denied" usually means your current user doesn't have permission to run a command. Try writing 'sudo' before the command. If that doesn't help then I'm unsure how to help, as I have not seen that error before.

I writing 'sudo' before the command, But error same as last.

I've just done some work improving the compatibility of the library and I've worked out what was going on with this issue. Although the library raises the warning:

ALSA lib conf.c:3750:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ default

It does not affect MAME or the library's performance. Everything will be working as normal. The error is caused by MAME not being able to setup sound for the game. If you do want sound for some reason and you have no screen then have a look at this forum: https://unix.stackexchange.com/questions/105964/launch-a-fake-minimal-x-session-for-pulseaudio-dbus

I have also added documentation describing how to run the library without a screen.
