I am trying to use catboost to predict multiclass, but I got an error as below. 

Error: loss function is not supported for GPU learning MultiClass

I used catboost option as below.

CatboostClassifier(loss_function='MultiClass',task_type='GPU')

I wonder if I can use GPU to predict multiclassification.

  • In issue 228, the Catboost team claims this is available in the latest release which you can build from source: https://github.com/catboost/catboost/issues/228 – BoboDarph Sep 04 '18 at 06:56
  • @BoboDarph I read that, but it does not work though I have the latest one.. – Ken Kim Sep 04 '18 at 07:44
  • You should build code from source using the instruction: https://tech.yandex.com/catboost/doc/dg/installation/python-installation-method-build-from-source-linux-macos-docpage/. Or you can wait for a few days, when the new version will be published on pypi, it will be there in the middle of September in version 0.10. – Anna Veronika Dorogush Sep 07 '18 at 16:19
