Bases: BotorchWarning

Warning raised when numerical issues are detected.

botorch.exceptions.warnings.legacy_ei_numerics_warning(legacy_name)[source]

Raises a warning for legacy EI acquisition functions that are known to have numerical issues and should be replaced with the LogEI version for virtually all use-cases except for explicit benchmarking of the numerical issues of legacy EI.

Parameters:

  • legacy_name (str) – The name of the legacy EI acquisition function.

  • logei_name – The name of the associated LogEI acquisition function.

Return type:

None
