Question about torch.svd #5

Open XMU-qcj opened 2 years ago

svd_cpu: the updating process of SBDSDC did not converge (error: 2)

paul007pl commented 2 years ago

I also met this issue frequently for clean data registration. I think it should be a bug with the svd function, because many previous methods also observe this issue.

Based on my experience, here are two suggestions:

  1. Use another random seed, and re-train.
  2. Using the hyper-parameter estimation sub-network may help.
