Bug Report for pyAMI provenance node structure inconsistency between Python 2 and Python 3

I'm seeing a bug between pyAMI v5.1.2 on CVMFS with inconsistent return structure for the provenance node dicts. The docs mention that for the pyAMI.atlas.api.get_dataset_prov API the return should be

a map of python dictionnaries. The key "node" gives a list of dataset with the distance to the given dataset and the key "edge" gives the list of successive pairs of input an output datasets.

This is true for Python 2.7, but for Python 3 the return structure is inconsistent with some datasets in the provenance node list having a return of

Regression in jaxlib v0.1.58 for jax.scipy.special.gammaln for CPU

In pyhf we've noticed one of our unit tests that was passing for jax v0.2.7 and jaxlib v0.1.57, however, with the release of jaxlib v0.1.58 it has started failing. We've narrowed it down to being for jaxlib v0.1.58 with jax_enable_x64=True in CPU mode (aka, where our unit test run).

Minimal Reproducible Example

In a fresh Python 3.8 virtual environment

Writing and Reading JSON with `jsonlite`

Using the jsonlite library in R you can read, write, and manipulate JSON data.

This Gist contains an example (write_json.R) of writing a list containing ecological "data types" and arrays of column data types to a JSON file using jsonlite::write_json.

That JSON file nicely serializes a mapping of the key values (e.g., "FSH", "IHI") — the ecological data types — to the associated data — the column data types.

To use this serialization (a data structure written to file) an example is given (read_json.R) in which it is read into a data frame using jsonlite::read_json.
