yes, so checking this against the issues on the pymc-examples repository… In this issue: Time varying survival model (poisson regression) not porting to pymc v4
there’s a mention of a recent merge request titled “Adapted code for survival_analysis.ipynb to work with v4 #372”.
But I just checked out the pymc-examples/main branch and it looks like the survival_analysis.ipynb is currently a v3 notebook.
@OriolAbril @drbenvincent was it accidentally reverted to the pre-ported state?
