[Question] Where should I code the GPU buffer settings in the RL code?

[H-Hisamichi]

Dear All,

I am working on robot RL using a manager-based approach. A GPU buffer overflow error occurred, so I tried to manually specify the buffer, but I don't know where to code it.
I followed the troubleshooting steps in MySceneCfg class, but the following error occurred. It seems the configuration is in the wrong place.

I would appreciate any advice!

Hi there, you can reference this as an example:
