2_fusion.py failed to open display

[nhk035]

Hello,
Thans for your great jobs. I'm trying to run the code on my server without a screen, but I got "freeglut (test): failed to open display ''" error when 2_fusion.py. Any solution for a offscrren device to preparing data?

It's also mentioned in here
"Note that rendering and fusion is splitted as rendering might not work on all machines, especially remotely (e.g. through ssh) on machines without monitor."
My quick solution is plugging a screen for it.
