Something isn't working
InferenceData
left with 0 draws
#102
In pymc-devs/pymc#6835 (released in PyMC v5.7.0) the emission of the "tune" stat was changed to be a sampler-wise thing, which is why McBackend can no longer find it in the stored sample stats.
This triggered a second bug in
.to_inferencedata()
, where anp.repeat
was used instead of anp.fill
, leading to an empty array, that masked away all draws & stats.Credits for the discovery go to @mamacneil via https://discourse.pymc.io/t/using-mcbackend-to-store-samples/13529.
