KTR with more than 1 regressor gives error

[sandeepwadhwa0101]

Hi Orbit team,

I am trying to build a KTR model as explained in the demo (https://orbit-ml.readthedocs.io/en/latest/tutorials/ktr2.html). The demo example builds model with more than 1 regressor columns; however, I noticed the code-version used in branch is 1.1.3dev, while public version is 1.1.2.

When I try to build a KTR model with more than 1 regressor, I get error -- "IllegalArgument: Wrong dimension length in Regression Param Input "

Does that mean that version 1.1.2 doesn't support KTR with more than 1 regressor?

Nevermind - the issue was caused because of regressor_sign=["+"], -- once I removed that, it is working fine.
