A workaround is to rebuild the dataset after each call tolgb.cv. For exmple: fromsklearn.datasetsimportload_digitsimportlightgbmaslgbX,y=load_digits(n_class=3,return_X_y=True)train_data=lgb.Dataset(X,y)categorical_feature=[0,2]param={'min_data_in_leaf':15,'min_child_samples':30,'fe...
In the full synchronization phase, bfile, sdo_geometry, urowid, interval (precision greater than 6 digits), and user-defined types are not supported. In a full synchronization for the table structure, the length of the char and varchar2 types in the source database automatically increases by ...

Instead, we have a frequency-bin entry for every number of the same "shape", such as##or###or#.###, with#standing in for digits. (For compatibility with earlier versions of wordfreq, our stand-in character is actually0.) This is the same form of aggregation that the word2vec vocab...
