Hello, I’m trying to use the arviz summary method like az.summary(idata.prior) but keep getting: ValueError: could not broadcast input array from shape (9,3) into shape (9,) My prior has the following dimensions: (chain: 1, draw: 500, aoa: 297, spline: 40) Has anyone else encountered the same…

I copy-pasted your code, adding: idata = pm.sample_prior_predictive() az.summary(idata, group='prior', var_names=['beta', 'tau', 'sigma']) and it ran fine. How are you generating your prior draws?

Apparently it was about the var_names parameter as it ran fine now after adding it. Thanks a lot!
