onelearn: Online learning in Python

Documentation | Reproduce experiments |

onelearn stands for ONE-shot LEARNning. It is a small python package for online learning with Python. It provides :

  • online (or one-shot) learning algorithms: each sample is processed once, only a single pass is performed on the data
  • including multi-class classification and regression algorithms
  • For now, only ensemble methods, namely Random Forests

Installation

The easiest way to install onelearn is using pip

pip install onelearn

But you can also use the latest development from github directly with

pip install git+https://github.com/onelearn/onelearn.git

  • Unable to pickle AMFClassifier.

    Unable to pickle AMFClassifier.

    I would like to save the AMFClassifier, but am unable to pickle it. I have also tried to use dill or joblib, but they also don't seem to work.

    Is there maybe another way to somehow export the AMFClassifier in any way, such that I can save it and load it in another kernel?

    Below I added a snippet of code which reproduces the error. Note that only after the partial_fit method an error occurs when pickling. When the AMFClassifier has not been fit yet, pickling happens without problems, however, exporting an empty model is pretty useless.

    Any help or tips is much appreciated.

    from onelearn import AMFClassifier
    import dill as pickle
    from sklearn import datasets
    
    
    iris = datasets.load_iris()
    X = iris.data
    y = iris.target
    
    amf = AMFClassifier(n_classes=3)
    
    dump = pickle.dumps(amf)
    amf = pickle.loads(dump)
    
    amf.partial_fit(X,y)
    
    dump = pickle.dumps(amf)
    amf = pickle.loads(dump)

    A problem is that @jit functions don't work with coverage... a workaround is to disable using the NUMBA_DISABLE_JIT environment variable, but breaks the code that use @jitclass and .class_type.instance_type attributes
