ImportError when importing xgbod

[vaibhavkarve]

Importing the xgbod model is throwing an import error. I suspect this is due to sklearn removing the _joblib_parallel_args fix from its latest version.

• Python version = 3.10.4

• OS = MacOS (darwin)

• pyod version = 1.0.0

• scikit-learn version = 1.1.0

• Observed behavior (in the REPL) --

>>> import pyod.models.xgbod
lib/python3.10/site-packages/xgboost/compat.py:36: FutureWarning: pandas.Int64Index is deprecated and will be removed from pandas in a future version. Use pandas.Index with the appropriate dtype instead.
  from pandas import MultiIndex, Int64Index
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "lib/python3.10/site-packages/pyod/models/xgbod.py", line 26, in <module>
    from .iforest import IForest
  File "lib/python3.10/site-packages/pyod/models/iforest.py", line 13, in <module>
    from sklearn.utils.fixes import _joblib_parallel_args
ImportError: cannot import name '_joblib_parallel_args' from 'sklearn.utils.fixes' (/lib/python3.10/site-packages/sklearn/utils/fixes.py)

Expected behavior -- no error on importing the xgbod model.

it actually caused by the underlying iforest's feature importance. will submit a new version today

pip install pyod==1.0.1 should fix the issue

That did indeed fix the import error. Thank you so much for such prompt action! 👍🏽 🥂
