KeyError: 'C'

[ilaudo]

Hello, I just recently updated to the current version of SMT in my Spyder environment, and now each time I try to train my Kriging model using the following line of code:
test_kriging = KRG(theta0=[1e-6], print_global=False)
I recevie the following error:
KeyError: 'C'

I have never received this error before, and tried training my model on data I know has worked before; however, I continually receive this error. Am I missing something obvious here, or is this an issue of the code?
As well, I noticed that before updating, theta0 could be set to much smaller values than 1e-6--was this another new change within the update? Thanks!

Hi, could you provide the full error message (traceback showing where the error is raised)? You can also just copy this example in a test_krg.py file and run it to see if you get the same error.

For the second points, theta bounds are intended to be controlled by theta_bounds option (default is [1e-6, 20]). Sorry, you may be the collateral victim of a bug fix (maybe in #544). Just set theta_bounds option as desired.
