Check create_error_model
Check what does the BayesInference class attribute "use_error_model" does:
- It seems to call a "create_error_model" in the post_sampler parent class (the child classes have a similar version of it), which calls a "create_model_error" function in the surrogate class that no longer exists (it used to create a GP for the error, like PCE+GP)
- It needs a bias_inputs variable, which is always set to None.
