Python Sklearn / Scikit＆cx_freeze：模块'sklearn.tree._criterion'没有属性'Criterion'

Question

我目前正在尝试将一个使用Sklearn模块的Python应用程序放在一个独立的.exe文件中。

我现在的cx_freeze setup.py看起来像这样：

import os
from cx_Freeze import setup, Executable

base = "Win32GUI"

os.environ['TCL_LIBRARY'] = r'C:\Users\...\AppData\Local\Continuum\anaconda3\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\Users\...\AppData\Local\Continuum\anaconda3\tcl\tk8.6'

executables = [Executable("gui_handler.py", base=base)]

packages = ["idna", "numpy", "sklearn", "nltk", "stop_words", "scipy", "scipy.sparse.csgraph._validation",
            "scipy.spatial.ckdtree", "PyQt5", "imblearn.under_sampling", "imblearn.over_sampling",
            "sklearn.tree._criterion"]

options = {
    'build_exe': {
        "packages": packages,
        "excludes": ["scipy.spatial.cKDTree"],
        "zip_include_packages": ["sklearn", "nltk", "idna"] # PyQt5 zippen verschlechtert die Optik
    },
}

setup(
    name="<any name>",
    options=options,
    version="1.0",
    description='<any description>',
    executables=executables
)

它之前运行良好，但我的应用程序的最新版本使用模块imblearn。我认为它会导致这个问题（双击.exe文件后几秒钟出现）：

AttributeError: module 'sklearn.tree._criterion' has no attribute 'Criterion'

我查看了sklearn\tree\tree.py文件，确实有这个import语句：

from ._criterion import Criterion

同一文件夹包含以下文件：

_criterion.cp36-win_amd64.pyd _splitter.cp36-win_amd64.pyd _tree.cp36-win_amd64.pyd _utils.cp36-win_amd64.pyd

据我所知，这是python模块文件。

如果我从PyCharm IDE执行它，应用程序运行完全正常，所以我会假设我的程序甚至不需要Criterion模块（并且cx_freeze只是加载它因为它加载了所有内容）因此我没有收到错误消息在运行时。或者该模块实际上已丢失。

什么想法可以解决这个问题？

Answer 1

好的，我自己解决了这个问题。

我刚刚删除了该行

zip_include_packages": ["sklearn", "nltk", "idna"]

来自我的cx_freeze_setup.py。
