Currently, I’m considering to use GP regression for a my project. I typically use following script is to train a GP regression model with PyMC3. X // features y // target with pm.Model() as model: ℓ = pm.Gamma("ℓ", alpha=2, beta=1) η = pm.HalfCauchy("η", beta=5) cov = η **…

Thanks @indian312 , Don’t need a loop, just by setting shape of length scale as X.shape[1] (number of features) we can achieve that. ℓ = pm.Gamma("ℓ", alpha=2, beta=1, shape = X.shape[1]])

So can I achieve that by simply setting the shape of ℓ and η to X.shape[1] (number of features) ?
