Confusion about the number of GPUs
When I tried to render the Mujoco model with a specified GPU, I got some confusion, which may be very simple.
When the following code is executed, I can find Found 3 GPUs for rendering. Using device 0 in the Pycharm console window.
image = sim.render(width=300, height=300, camera_name = 'cam0', depth=False, device_id=0)
However, when I use pytorch to detect the number and name of GPU, the related codes and displays are shown below
print('Number of gpu: ', torch.cuda.device_count())
print('its name： ', torch.cuda.get_device_name(0))
Number of gpu: 1
its name： NVIDIA GeForce RTX 3070 Ti
(1) Why the numbers of GPUs detected by the two methods are different?
(2) For Mujoco, how can I check the names of the detected GPUs?
(3) After I installed the Nvidia driver, the default installation path was /usr/src instead of /usr/lib. Then, I use ln -s to create a new folder /usr/lib/nvidia-510. However, there is no libGL.so mentioned in some other issues.
Hope to get some replies!
Hi. I have the same problem. Have you found the answer?
Sry, no idea right now...
