PyInstaller“ValueError：太多值无法解压”

pyinstaller 版本 3.2

操作系统：win10

我的 python 脚本在 Winpython Python 解释器中运行良好。

但是当我使用 Pyinstaller 包时，python 脚本包含 caffe 模块， 我将面临的问题是：“您可以使用以下命令加载 I/O 插件skimage.io.use_plugin” https://stackoverflow.com/questions/34761862/pyinstaller-you-may-load-i-o-plugins-with-the-skimage-io-use-plugin

我按照上面的答案修复我的规范文件（挂钩文件？？）。我收到以下错误：（ValueError：太多值无法解压）

这是我的规格文件：

# -*- mode: python -*-
block_cipher = None

a = Analysis(['Demo_GenderAge.py'],
         pathex=['D:\\Work\\test_code\\PyInstaller_Test_caffe'],
         binaries=None,
         datas=["skimage.io._plugins"],
         hiddenimports=['skimage.io._plugins'],

         win_no_prefer_redirects=False,
         win_private_assemblies=False,
         cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
         cipher=block_cipher)
exe = EXE(pyz,
      a.scripts,
      exclude_binaries=True,
      name='Demo_GenderAge',
      debug=False,
      strip=False,
      upx=True,
      console=True )
coll = COLLECT(exe,
           a.binaries,
           a.zipfiles,
           a.datas,
           strip=False,
           upx=True,
           name='Demo_GenderAge')

有人可以告诉我如何解决它吗？

The datas数组需要元组，而不是字符串。来自pyinstaller 文档 https://pyinstaller.readthedocs.io/en/stable/spec-files.html#adding-data-files:

数据文件列表是元组列表。每个元组有两个值， 两者都必须是字符串：

• 第一个字符串指定当前系统中的一个或多个文件。
• 第二个指定运行时包含文件的文件夹的名称。

我想将上述信息应用到您的代码中会导致以下结果：

...    
datas=[("skimage.io._plugins", '.')],
...

我希望这有帮助！
