GBReweighter KeyError: 'squared_error' ?? about hep_ml

[arogozhnikov]

See the deprecation message from sklearn documentation:

Deprecated since version 1.0: Criterion “mse” was deprecated in v1.0 and will be removed in version 1.2. Use criterion="squared_error" which is equivalent.

I guess you need to update sklearn.

thanks for the response, I updated sklearn "pip install -U scikit-learn" now the version is scikit-learn-1.1.1 but I still get the exact same error. Do you reckon that I need to update any other packages?

[arogozhnikov]

Can't think about any other issue. Make sure to restart kernel, and verify sklearn by

print(sklearn.__version__)

Hi everyone,

I am having an issue similar to the one @oozcelik reported, as shown bellow. I tried to update sklearn, as suggested by @arogozhnikov but also got the same error message.

hi, I managed to get it work after deleting some files in my CERN BOX which causes conflict.

Hi @oozcelik, what do you mean when you say that some files were causing conflict? I am not sure about which files I have might be related to this problem.

[arogozhnikov]

ensure you do use the new version of sklearn (should be run within the same process/notebook as hep_ml): print(sklearn.__version__)
