pyinstaller build生成可执行文件后添加文件的位置

Question

I built an executable file for my python application using pyinstaller. I added two folders (data and audio samples) by using --add-data command. The executable is working. But where can I find the two data folders I added. Aren't they put into the dist folder with executable file?

Answer 1

When you add a data to PyInstaller it would bring your data and extract it in one-file mode in temp folder (eg on Windows it would be something like C:\\Users\\<User>\\Appdata\\local\\temp\\_MEI60482\\ ) so you need to change your code to open your files from that directory. A good practice is to use this function in your code to retrieve your data. When running executable sys._MEIPASS would be equal to the PyInstaller temp folder.

def resource_path(relative_path):
    if hasattr(sys, '_MEIPASS'):
        return os.path.join(sys._MEIPASS, relative_path)
    return os.path.join(os.path.abspath("."), relative_path)

Then you can use it with something like source = resource_path("audio.zip") .
