1. 파일 추가

[PYTHON PATH]\Lib/site-package/_pyinstaller_hooks_contrib/stdhooks 폴더에 hook-xgboost.py 파일을 생성

""" hook-xgboost.py """
from PyInstaller.utils.hooks import collect_all
datas, binaries, hiddenimports = collect_all("xgboost")

pyinstaller --collect-all "xgboost" test.py

--add-data "[file_path]; [dir_path]"

--hidden-import "[library]"
