AttributeError: 'list' object has no attribute 'items'

I will first delete obs but we need this for plot_ppc()

[hyunjimoon]

This is resolved by delivering the dictionary for only _obs directly to stan.sample.

However, the idata_kwargs auto update is needed: code ran without the following line (and we drew plot_ppc), but need rechecking before closing this issue.
