When I finished installation of hgboost and try to import hgboost,there is something wrong,could you please help me out? Details are as follows:

ImportError Traceback (most recent call last)

Can you try the Colab notebook to see whether it works? https://colab.research.google.com/github/erdogant/hgboost/blob/master/notebooks/hgboost_classification_examples.ipynb

it works,made me confused?maybe it's requirement package version issues? When the following changes are made in the "treeplot\treeplot.py" file,,the problem was solved:

from sklearn.tree.export import export_text --> from sklearn.tree import export_text.

Thank you for this suggestion! I fixed it in the treeplot library and it should work now.
