pyinstaller打包含有pickle.loads语句的程序时出错

[kingsser16]

目标：
在fortran中调用python的随机森林模型进行预测


事情经过：
本人使用sklearn包中的ensemble随机森林训练了模型，用pickle.loads调用模型进行预测，程序编写无误后使用pyinstaller打包
预测程序中仅使用以下额外包

import numpy as np
import datetime
import pickle

使用

pyinstaller -F temp0201.py

打包，打包之后运行exe，提示No module named 'sklearn'，便使用

pyinstaller -F temp0201.py --hidden-import sklearn

进行打包，运行exe提示No module named 'sklearn.ensemble.forest'，便使用

pyinstaller -F temp0201.py --hidden-import sklearn.ensemble.forest

进行打包，运行exe提示No module named 'sklearn.tree.tree'，便使用

 pyinstaller -F temp0201.py --hidden-import sklearn.ensemble.forest --hidden-import sklearn.tree.tree 

进行打包，运行exe提示

sklearn\utils\deprecation.py:143: FutureWarning: The sklearn.ensemble.forest module is  deprecated in version 0.22 and will be removed in version 0.24. The corresponding classes / functions should instead be imported from sklearn.ensemble. Anything that cannot be imported from sklearn.ensemble is now part of the private API.

Traceback (most recent call last):

    model_ran = pickle.loads(s2)
  File "sklearn\tree\_tree.pyx", line 655, in sklearn.tree._tree.Tree.__setstate__
KeyError: 'max_depth'

便使用

pyinstaller -F temp0201.py --hidden-import sklearn.ensemble --hidden-import sklearn.tree

进行打包，运行exe再次提示

 No module named 'sklearn.ensemble.forest'

请问大佬们这是发生什么事了，怎么回事
谢谢大佬们
