Python installation does not work when calling `fit` #8

Open mrektor opened 3 years ago

Hi,

After the installation of the dependencies and of the python library, when calling the fit method (executing the code from the example.py) it gives this error:

Traceback (most recent call last):
  File "example.py", line 17, in <module>
    model.fit(X, y)
  File "/home/ettore.mariotti/Documents/gosdt_repo/GeneralizedOptimalSparseDecisionTrees/python/model/gosdt.py", line 99, in fit

Hello @mrektor,

Have you ever figured out how to solve this? Cause when I fit it, it gives me AttributeError: module 'gosdt' has no attribute 'confirue'!

We have a new repo with pip install. Please check https://github.com/ubc-systopia/gosdt-guesses and https://pypi.org/project/gosdt/. We also include an example.py and tutorial.ipynb in our new repo.

Thank you for the help. I changed a part of a code, and it ran.

Best, Farnaz
