AtributeError mensage during fit

[luizhemelo]

Hi everyone!!

I've received the atribute error message below when using FLAML with XGBoost (this error occurs with others algorithms too):

[flaml.automl: 07-01 10:45:34] {908} INFO - Evaluation method: cv

    "estimator_list": ['xgboost'],

    "log_file_name": 'ft.log',
}

Specifications: Python 3.7.10 FLAML 0.5.4 (installed via PiP) XGBoost 1.4.0 (installed via conda)

Any ideas?

Thanks! :D

Hi @luizhemelo Is ray installed in your environment? If so, which version is it?

[luizhemelo]

I didn't have Ray installed, @sonichi. After installation it worked perfect!! Thanks a lot!! :D

[sonichi]

It's supposed to work both with and without ray installation. So I don't really know what caused the error and I can't reproduce that error. Anyway, we'll remove the use of ConcurrencyLimiter in the next version.
