Note however that some estimators will run in sequential mode instead of leveraging thread-based parallelism. *** )renvirontextwrapdedentrstripsplitrrintlen Exceptionwarningswarn) coderrZopenmp_exceptionoutputZnthreadsZopenmp_supported exceptionmessagerrrcheck_openmp_support(sP     r*) __doc__rr rr$Zpre_build_helpersrrr*rrrrs
