CUDA error: an illegal memory access was encountered

[xuchuyong]

when calling ‘‘set_dof_state_tensor_indexed’’, error occurs as “RuntimeError: CUDA error: an illegal memory access was encountered”:

I have a similar problem. After using the set_dof_state_tensor_indexed, I can not access certain tensors such as root_states and get the following error.

RuntimeError: CUDA error: an illegal memory access was encountered
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with TORCH_USE_CUDA_DSA to enable device-side assertions

Please help!

The documentation mentions this issue briefly:
