使用具有 sklearn 包和 xgboost 的 pyinstaller 运行 exe 时出错

Question

我从一个 python 文件制作了一个 exe 文件，该文件有多个从我们自己的文件导入的文件，并且有包 sklearn、xgboost、pandas 和其他 sklaern 包。在 exe 准备过程中，运行它时没有错误会抛出错误

当它在找不到 xgboost 的 dll 文件时抛出错误但它为 sklearn 抛出错误时，我使用了为 xgboost 添加数据。我已经制作了一个文件的 exe，但该文件通过使用 import 调用其他其他 python 文件函数。

Answer 1

sklearn 和 xgboost 在与 Pyinstaller 一起使用时需要特别小心。我正在跳过导入 xgboost 但这里有一个有用的 answer 关于将它与 Pyinstaller 一起使用。

似乎当你添加xgboostPyinstaller 无法处理像scipy 这样的一些模块。一种简单的方法是将 Python 的 sit-package 中的整个 scipy 作为数据添加到您的可执行文件中。所以编辑你的规范文件并在Analysis之后添加：

# -*- mode: python -*-

block_cipher = None


a = Analysis(
datas=[('./env/xgboost/*', 'xgboost/'), ('./env/Lib/site-packages/xgboost/VERSION', 'xgboost/')],
    ...
)
# add here
a.datas += Tree('<path_to_scipy_in_python_dir>', prefix='scipy')
...
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)

最后，使用pyinstaller script.spec 生成您的可执行文件。
