Pyinstaller sklearn reports errors

The program is in pycharm Can be executed normally

have access to pyinstaller Generate exe

But enforcement exe when , Always prompt no _reduce_python（ I forgot what it was ） attribute

use hidden import It's no use
My solution ： Delete sklearn Irrelevant in Library py file , Only those related to program execution are reserved py file , modify sklearn Of _init_.py, Delete irrelevant statements , Only the statements related to the required model related to program execution are retained .
