❓ Questions and Help

Hallo,
I met an issue during training a motion planner:
RuntimeError: There was an error while running the linear optimizer. Original error message: torch.linalg.solve: (Batch element 1): The solver failed because the input matrix is singular.. Backward pass will not work. To obtain the best solution seen before the error, run with torch.no_grad()

I have tried to use LevenbergMarquardt, but the issue is still there, could you please give me some advice?
Thank you in advance!
