I’m currently trying to simulate 8 or so cameras at once while having them all publish with ROS. However, it seems like doing so causes my GPU to run out of memory (RTX 2080, 8 GB). I’ve found that I can get up to around 4 cameras working at the same time, using up ~7.2 GB. Are there any methods for lowering the memory usage for many-camera use cases?
EDIT: I thought I should mention that I am effectively only using the cameras for ROS. If there’s a way to disable them rendering to viewports while still updating in ROS, that might also help.
We are aware of the memory usage of the multi camera, and also about the limitation that the camera is tied to the viewport. We are working on it for the next release.
Thanks ! but how to set multi camera with multi GPU ? I run my robot in isaacsim container on remote headless machine with 8 X 3080TI ? It runs normally but the omnigraph’s publisher rate is very low , less than 10hz
We have 2 GeForce RTX 3080. Having only 6 robots, each with a camera (with which we capture a depth image), results in taking half of the memory of each GPU. The camera resolution is only 171 x 224… Is it normal that it takes so much GPU RAM ? Or are we doing something wrong ?
Without the cameras, we can easily have 100 robots.
