python - 依赖于 dlib 的 python 可执行文件不起作用

问题描述

大家好，我有一个依赖于 dlib 的 python 脚本，例如 import dlib 现在我已经创建了一个可执行文件（使用 pyinstaller），它在我的机器上运行良好，但出现 ImportError: DLL load failed: A dynamic link library (DLL ) 初始化例程在另一台机器上失败。在挖掘出发生这种情况的行之后，基本上是导入 dlib，这让我认为 dlib 没有正确包含在我的可执行文件中。我的 dlib 版本 19.18.0 和我试图运行 exe 的另一台机器没有安装 python。需要帮助 另一台机器上的错误

解决方案

由于某种原因，Pyinstaller 似乎没有选择 dlib。在命令行上构建二进制文件时，请尝试使用以下标志将 dlib 显式添加到包中pyinstaller --hidden-import dlib。
