Source Idx1

Loads records from an IDX1 file

class dffml.source.idx1.IDX1Source(config)

Source to read files in IDX1 format (such as MNIST digit label dataset).

CONFIG

alias of IDX1SourceConfig

class dffml.source.idx1.IDX1SourceConfig(filename: str, feature: str, readwrite: bool = False, allowempty: bool = False)

class dffml.source.idx1.IDXSourceConfig(filename: str, feature: str, readwrite: bool = False, allowempty: bool = False)

no_enforce_immutable()

By default, all properties of a config object are immutable. If you would like to mutate immutable properties, you must explicitly call this method using it as a context manager.

Examples

>>> from dffml import config
>>>
>>> @config
... class MyConfig:
...     C: int
>>>
>>> config = MyConfig(C=2)
>>> with config.no_enforce_immutable():
...     config.C = 1
