I want to optimize the placement of an object. But when I try this , I failed to get the gradient of the object's position. Then I find this is because the object's position is not trainable. I want to make a scene object's position trainable. How can I achieve this? And why I fail?

Hi @qiangdadi,

You need to provide more context to report an issue.

This is a simple code. It is very simple. I just want to make the position of a scene object (not a transmitter\receiver\material\camera) to be trainable. Screenshot from 2024-09-16 17-40-53

Sorry for the trouble made by me. And I tried to provide more details.
