I am trying to use sample_posterior_predictive but getting this error. As per the threads I should remove samples and keep_size which I did. But i didn’t thinned any data from trace for sample posterior predictive. Not able to understand the thinned concept. [image]

ValueError: conflicting sizes for dimension 'chain': length 1 on the data but length 2 on coordinate 'chain'
