Ungroup

class bayesflow.adapters.transforms.Ungroup(key: str, prefix: str = '')

Bases: Transform

Ungroups the the variables in key from a dictionary into individual entries. Most transforms do not support nested structures, so this can be used to flatten a nested structure. It can later on be reassembled using the bayesflow.adapters.transforms.Group transform.

Parameters:

keystr

The name of the variable to ungroup. The variable has to be a dictionary.

prefixstr, optional

An optional common prefix that will be added to the ungrouped variable names. This can be necessary to avoid duplicate names.
