Error when running test_accuracy: __init__() got an unexpected keyword argument 'min_impurity_decrease'

[pawelswoboda]

After installing dependent packages in debian and running test_accuracy.py, I get the following error:

Traceback (most recent call last):
File "test_accuracy.py", line 107, in
file_CART=r'./accuracy/cart_compas.txt', file_OSDT=r'./accuracy/osdt_compas.txt')
File "test_accuracy.py", line 67, in test_accuracy
min_impurity_decrease=lamb
TypeError: init() got an unexpected keyword argument 'min_impurity_decrease'

How can I make it work?
