fatf.utils.array.tools.as_unstructured(array_like: Union[numpy.ndarray, numpy.void], **kwargs) → Union[numpy.dtype, numpy.ndarray][source]

Converts an array like object into an unstructured array.

If the input array is unstructured, it is return without any transformations. Otherwise, if the input array is either a structured array or a structured array row, appropriate structured to unstructured function is called.


Since this function either calls a local implementation or a builtin numpy function there may be some inconsistencies in its behaviour. One that we are aware of is conversion of arrays that contain 'V' – raw data (void), 'O' – (Python) objects, 'M' – datetime or 'm' – timedelta dtypes. These types are not supported by the local implementation, however some of them are supported by the numpy built-in, e.g. the 'V' type.

array_likeUnion[numpy.ndarray, numpy.void]

An array, a structured array or a row of a structured numpy array to be converted into a plane numpy array representation.


Named parameters that are passed to the appropriate structured to unstructured array converter. These parameters are ignored when calling any of the local implementations – see either fatf.utils.array.tools.structured_to_unstructured_row or fatf.utils.array.tools.structured_to_unstructured documentation for details.

classic_arrayUnion[numpy.dtype, numpy.ndarray]

A classic numpy array or numpy dtype (in case the structured row has just one element) representation of the structured_row with the most generic type out of the input row’s dtypes.


The input array is not a numpy array, a structured numpy array or a row of a structured numpy array.


The input array consists of complex types such as numpy void and object-like types that are not supported by this function.
