Custom logger is already specified. Specify more than one logger at same time is not thread safe

[Pedklin]

Catboost ends with error "Custom logger is already specified. Specify more than one logger at same time is not thread safe" and gives no result. Tried to update catboost version to 1.26.0 but the error remained. Are there the ways to fix it?

Catboost ends with error "Custom logger is already specified. Specify more than one logger at same time is not thread safe"

is it a warning, not an error. The real error must be something else.

Please create an issue about this with the description how to reproduce the error.

catboost version to 1.26.0

Are you running an inference package for Node.js?

It is hard to reproduce... I use python module created by PyInstaller. It incorporates a lot of ML python's methods. All of them work (more or less) but CatBoost not.
As I understand from #1855
the only way to fix the problem now is to correct catboost/catboost/libs/logging/logging.cpp
and rebuild CatBoost manually?

#1855 has been fixed since release 1.0.6. You should not have this error when using modern versions of CatBoost.

No, it is a symptom, not a cause. If this warning is still present the logic is still broken somewhere (most likely when setting custom loggers), but not in this file.
