Can’t retrieve results showed in introductory overview

Questions v5
1

Hello,
If I follow the introductory overview presented here
https://www.pymc.io/projects/docs/en/latest/learn/core_notebooks/pymc_overview.html

I do not match exactly the posterior distributions presented in the overview, notably the beta[0] is not centred in 1. I forced using 2 chains like in the overview.

I am using pymc v5.10.3

Can you show the results you got? How much non-centered around 1 is it?
