utils.converters.ToFloatConverter(back_conversion: Callable | None = None)

Conversion from numpy array of various data formats to float and back

Methods

Name	Description
from_timestamp_with_offset	Convert timestamp back to datetime with offset.
to_float	Convert numpy array to float, handling various data types.
to_orig	Convert back to original data type from float.

from_timestamp_with_offset

utils.converters.ToFloatConverter.from_timestamp_with_offset(
    ts: datetime.timestamp,
    offset: float,
)

Convert timestamp back to datetime with offset.

Parameters

Name	Type	Description	Default
ts	float	Timestamp value (seconds since epoch, with offset removed).	required
offset	float	Offset timestamp to add back (seconds since epoch).	required

Returns

Name	Type	Description
	datetime	Datetime object reconstructed from timestamp and offset.

to_float

utils.converters.ToFloatConverter.to_float(x: np.ndarray)

Convert numpy array to float, handling various data types.

Parameters

Name	Type	Description	Default
x	np.ndarray	Input array with elements of the same type (datetime, float, or int).	required

Returns

Name	Type	Description
	np.ndarray	Array converted to float. For datetime objects, converts to timestamps offset from the first value.

Raises

Name	Type	Description
	AssertionError	If input array contains mixed types.

to_orig

utils.converters.ToFloatConverter.to_orig(x: np.ndarray)

Convert back to original data type from float.

Converts to the type of the last input of self.to_float.

Parameters

Name	Type	Description	Default
x	np.ndarray	Float array to convert back to original type.	required

Returns

Name	Type	Description
	np.ndarray	Array converted to original data type.
