I’m a new user of Pyro and I need some help. I’m trying to make a dimensionality reduction using the algorithm in the ( tutorial 1 from the paper GrandPrix 2019. The problem that I’m having is that when I run the code for my data (803 rows, 14 columns ) this error always shows up:
Luu = Kuu.cholesky()
RuntimeError: cholesky_cpu: U(29,29) is zero, singular U.
SGPR/SparseGPRegression/X dist | 803 2
value | 803 2
I’m using the latest version of Pyro. Can you have any suggestions??
Thanks in advance.
