Problem with GridSearch

[zzirend]

Hello,
Hope you are doing very well.
I run the model in order to determine the best model (with GridSearch). But it runs with the following problem:
'GradientBoostingClassifier' object has no attribute 'presort'

I couldn't fix it. please help me.
Thank you

Hey @zzirend ,

What specific error is raised? in which file and line? Can you please send the traceback?

Thanks,

Hi, I am getting the same problem, and here is the error message:

Hi @x4nth055 , I am getting the same problem as well

    if not model:
  File "/Users/ruchirs/ser/emotion-recognition-using-speech/emo-env/lib/python3.9/site-packages/sklearn/ensemble/_base.py", line 180, in __len__
    return len(self.estimators_)

Hey @ruchirsachdeva and @NeneMatsuki,

I just tried to run the grid_search.py script and it worked fine, I think it's related to sklearn's version, please downgrade to 0.24.2 to be able to run the project properly:

$ pip install scikit-learn==0.24.2

Please let me know if it persists.

I got same error.

@x4nth055 I tried this version scikit-learn. Still same problem.

嗨，我也遇到了同样的问题

    if not model:
  File "/Users/ruchirs/ser/emotion-recognition-using-speech/emo-env/lib/python3.9/site-packages/sklearn/ensemble/_base.py", line 180, in __len__
    return len(self.estimators_)
AttributeError: 'RandomForestClassifier' object has no attribute 'estimators_'

我遇到了同样的错误。

我尝试了这个版本。还是同样的问题。scikit-learn
