modelrunner.storage.utils module

Functions and classes that are used commonly used by the storage classes.

class Array(input_array, attrs=None)[source]

Numpy array augmented with attributes

decode_binary(obj_str)[source]

decode an object encoded with encode_binary().

Parameters:: obj_str (str or bytes) – The string that encodes the object
Returns:: the object
Return type:: Any

decode_class(class_path, *, guess=None)[source]

decode a class encoded with encode_class().

Parameters:

class_path (str) – The string that encodes the class
guess (type) – A class that is used if the encoded class cannot be found and the name of the guess matches the encoded class.

Returns:

the class or None if class_path was None

Return type:

type

encode_binary(obj: Any, *, binary: Literal[True]) → bytes[source]

encode_binary(obj: Any, *, binary: Literal[False]) → str

encodes an arbitrary object as a string

The object can be decoded using decode_binary().

Parameters:

obj – The object to encode
binary (bool) – Encode as a byte array if True. Otherwise, a unicode string is returned

Returns:

The encoded object

Return type:

str or bytes

encode_class(cls)[source]

encode a class such that it can be restored

The class can be decoded using decode_class().
