A bug: Segmentation fault (core dumped)

[ShiguangSun]

Hi, thank you for sharing your code.
When I run run.sh in a ubuntu server, I got a error:

warnings.warn(colorize('%s: %s'%('WARN', msg % args), 'yellow'))
CRITICAL:absl:OpenGL version 1.5 or higher required
CRITICAL:absl:OpenGL ARB_framebuffer_object required
CRITICAL:absl:OpenGL ARB_vertex_buffer_object required
./scripts/run.sh: line 10: 4276 Segmentation fault (core dumped)

But when I run it in my own computer, the error didn't appear. I can't fix it in the server, I'd appreciate any help on this error.

That's most likely an issue w/ DMControl rendering https://github.com/deepmind/dm_control#rendering. Make sure DMControl can render
