Issues about visual observation #20

Closed jiangranlv closed 1 year ago

jiangranlv commented 1 year ago

hi, yuanpei @cypypccpy. Nice work again! It seems like something is wrong when I try to use point cloud observation in the task. Specifically, using the camera through isaacgym API may have some bugs. I print the 'camera_handle', whose value is -1.

Could you please help me? Thanks a lot~

Hi @jiangranlv ,

Thanks. I just tried it and it should work fine:

python train.py --task ShadowHandOver --algo ppo

Errors that return -1 generally appear when using isaacgym on servers without a monitor, are you in this case? And using --headless may also cause this bug. Currently, isaacgym has many bugs with rendering, maybe you can also go to the isaacgym official forum to find some answers.

Hope this can help you.

I did use isaacgym on servers without a monitor, and using the headless mode. Thank you very much.
