pept.tracking.Swap#
- class pept.tracking.Swap(*swaps, inplace=True)[source]#
Bases:
Filter
Swap two columns in a LineData or PointData.
Filter signature:
LineData -> Swap.fit_sample -> LineData PointData -> Swap.fit_sample -> PointData
For example, swap the Y and Z axes:
Swap("y, z").fit_sample(points)
. Add multiple swaps as separate arguments:Swap("y, z", "label, x")
.You can also swap columns at numerical indices by single-quoting them:
Swap("'0', '1'")
.New in pept-0.4.3
Methods
__init__
(*swaps[, inplace])copy
([deep])Create a deep copy of an instance of this class, including all inner attributes.
fit
(samples[, executor, max_workers, verbose])Apply self.fit_sample (implemented by subclasses) according to the execution policy.
fit_sample
(sample)load
(filepath)Load a saved / pickled PEPTObject object from filepath.
save
(filepath)Save a PEPTObject instance as a binary pickle object.
Attributes
- property swaps#
- fit_sample(sample: IterableSamples)[source]#
- copy(deep=True)#
Create a deep copy of an instance of this class, including all inner attributes.
- fit(samples, executor='joblib', max_workers=None, verbose=True)#
Apply self.fit_sample (implemented by subclasses) according to the execution policy. Simply return a list of processed samples. If you need a reduction step (e.g. stack all processed samples), apply it in the subclass.
- static load(filepath)#
Load a saved / pickled PEPTObject object from filepath.
Most often the full object state was saved using the .save method.
- Parameters
- filepath
filename
orfile
handle
If filepath is a path (rather than file handle), it is relative to where python is called.
- filepath
- Returns
pept.PEPTObject
subclass
instance
The loaded object.
Examples
Save a LineData instance, then load it back:
>>> lines = pept.LineData([[1, 2, 3, 4, 5, 6, 7]]) >>> lines.save("lines.pickle")
>>> lines_reloaded = pept.LineData.load("lines.pickle")
- save(filepath)#
Save a PEPTObject instance as a binary pickle object.
Saves the full object state, including inner attributes, in a portable binary format. Load back the object using the load method.
- Parameters
- filepath
filename
orfile
handle
If filepath is a path (rather than file handle), it is relative to where python is called.
- filepath
Examples
Save a LineData instance, then load it back:
>>> lines = pept.LineData([[1, 2, 3, 4, 5, 6, 7]]) >>> lines.save("lines.pickle")
>>> lines_reloaded = pept.LineData.load("lines.pickle")
