python - 使用 pyinstaller 运行包含 xgboost 包的 exe 文件时出错

Question

我有一个用于预测某些值的代码，该代码在代码中使用xgboost包。当我在 PyCharm 中运行它时，它按预期运行。

问题是当我使用pyinstaller制作可执行文件时。它将使 exe 没有任何错误，但是当我运行它时，会出现以下错误:

这里出了什么问题？

Pyinstaller 似乎找不到 xgboost.dll , VERSION文件。因此，您需要手动将它们添加到输出包中。我还建议您使用 try/except阻止看看发生了什么。 假设这个简单的例子:

import traceback
try:
    import xgboost
    input("xgboost imported successfully!")
except Exception:
    traceback.print_exc()
    input("Import Error!")

我建议您使用env要构建脚本，您需要添加 xgboost目录位于<path_to_venv>/xgboost和VERSION文件位于<path_to_venv>/Lib/site-packages/xboost 。接下来，使用 pyinstaller 将它们添加为数据文件。启动您的环境并执行以下命令(我的虚拟环境名为 env ):

├───myscript.py
├───env

命令:

(env) > pyinstaller myscript.py -F --add-data "./env/xgboost/*;xgboost/" --add-data "./env/Lib/site-packages/xgboost/VERSION;xgboost/"
