【问题描述】:
我已使用 Pyinstaller 将我的程序(用 Python 3.6.1 编写,使用 Python 3.5.3 转换)从 .py 转换为 .exe。但是,它加载速度非常慢(大约需要 16 秒,而在 IDLE 中运行时需要 我优化了我认为 >问题是(导入大量模块,所以我将代码更改为只导入必要的模块部分)。在 IDLE 中运行它时,它加速了很多,但是当我用它创建一个 .exe 它完全一样(并且 我确实检查了我使用的是正确的 .py文件)。我似乎 Pyinstaller 只是将您在系统上安装的所有模块打包到 .exe 中,而不仅仅是实际使用的模块的一小部分(使用 --onefile 时)。如何确保 Pyinstaller 仅安装模块的必要部分或以其他方式加快速度,同时仍使用 --onefile 并将其打包成单个 .exe?
