RuntimeError: solve_cuda: U(459,459) is zero, singular U.

Thank you for sharing your amazing work!!

I'm trying to run the code using my own data, but singularity error happens every time.

I've checked that zwfcrazy raised the same issue. In response to this, RazvanRotaru said deleting the NBB and re-downloading it would help.
However, deleting NBB doesn't really help.

Could you help me to solve this problem?

fixed similar issue by using an older version of pytorch,

example, 1.10.1 worked for me:
!pip install torch==1.10.1+cu102 torchvision==0.11.2+cu102 torchaudio==0.10.1 -f https://download.pytorch.org/whl/torch_stable.html

Thanks:)
This works for me too!
