Hi,
The pickled scikit-learn model can be found in the DSS data directory, in analysis-data/PROJECT/ANALYSIS/MLTASK/sessions/SESSION/ppX/mY/clf.pkl
If you look at the URL when you are within a model in the DSS UI, it will give you all the necessary identifiers to find the proper clf.pkl
You can then use the classical mechanisms of Virtualbox to copy that to your local machine.
An important side note is that DSS performs various preprocessing on the features, so the clf.pkl expects as input the preprocessed data. You would need to apply the exact same preprocessing in order to score with that. DSS does not currently provide an officially supported way of scoring models from using only the clf or files.
