Hi, I have a question regarding mappers. To follow one of your examples, lets say we have;
In [8]: ds = dataset_wizard(np.ones((5, 4, 3))) In [9]: ds.a.mapper Out[9]: FlattenMapper(shape=(4, 3), auto_train=True) Now we select a subset; In [10]: ds = ds[:, [1,3,4]] In [11]: ds.a.mapper Out[11]: ChainMapper(nodes=[FlattenMapper(shape=(4, 3), auto_train=True), StaticFeatureSelection(dshape=(12,), oshape=(3,), slicearg=[1, 3, 4])]) So far, so good. If we now select a subset of this; In [12]: ds = ds[:, [0,1]] In [13]: ds.a.mapper Out[13]: ChainMapper(nodes=[FlattenMapper(shape=(4, 3), auto_train=True), StaticFeatureSelection(dshape=(12,), oshape=(3,), slicearg=array([1, 3]))]) In [14]: ds.shape Out[14]: (5, 2) Is the new StaticFeatureSelection not in the ChainMapper, or is it just a display issue?
