How to run gazebo with a specific graphic card or no graphic card?
Hey , I am trying to run a tensorflow image classifier along with a Gazebo simulation .
I have a Nvidia GT730 with 2GB graphics .
The problem i am facing is , when i start up gazebo , it eats up most of the GPU memory , this makes my tensorflow node as non run-able .
Is there some parameter i can give with gzclient , so that gazebo runs solely on the CPU or integrated GPU .

You can try using a virtual framebuffer like xvfb
to run gazebo on the CPU. Once you install xvfb
, run xvfb-run -s "-screen 0 1400x900x24" bash
. Launching gazebo from that bash shell will run rendering on the CPU. To check if your world is properly loaded, you can run gzclient
from another shell (which will use the GPU).

I have Gazebo 11.9.1. Using xvfb
did not show any gzclient
window, but also no errors. My hunch is that my screen id could be wrong.

This may sound simple, but had you tried starting your image classifier node first and pausing for a few seconds for it to start up, then starting gazebo.

That could be one solution .

Not sure, if it is an option for you, but running simulation headless should free some resources on your GPU.
