We are frequently running into disconnects that are not handled on the client side. Finally we were able to capture some relevant logging information: On the client side, the activity...

Add `logp` migration table to the migration guide

1

Even the core devs are struggling with `logp` migrations. We should have a before/after table with concise code examples for `logp` migrations. This includes: * `rv.logp()` * `pmodel.logp()` * with...

## Description of your problem The initial point evaluation, primarily in `init_nuts` is the one and only place in the `pm.sample` control flow when we want to add jitter. That's...

Imputation does not work in combination with pm.Data

14

## Description Even after https://github.com/pymc-devs/pymc3/pull/4439 imputations don't work in combination with `pm.Data`. This is because `pm.Data` creates a `SharedVariable` that currently does not support a `np.ma.MaskedArray`. Almost identical to the...

Every step method has a `stats_dtypes` dictionary that advertises the dtypes to be expected. This information is relevant for storage backends so they can create arrays of the correct dtypes....

To decrease our dependence on `MultiTrace`, and to improve support for workflows were `InferenceData` objects are saved to disk, the `EmpiricalGroup` approximation should be refactored. Currently it takes only `MultiTrace`...

Question/Feature request: Figuring out how often the model/gradient was evaluated by NUTS

5

This question came up during office hours: __Which sampler stat should be used to answer how often a model was evaluated during MCMC?__ @junpenglao @ColCarroll For example, these variables are...

Infer dims & coords from `xarray` variables passed to `pm.Data`

2

## Description The internal function `pm.data.determine_coords` is called when `pm.Data(..., export_index_as_coords=True)` is invoked. Right now it can only infer `coords` from `pd.Series`, or `pd.DataFrame`, but it would be nice (and...

Editing Zenodo metadata

Zenodo initially autogenerated the metadata from the full history. Without having strong opinions about it we decided to reduce that list to the contributors since the last Theano release (...

Video embeddings have broken layout and missing controls by default
