PyInstaller"ValueError:太多值无法解包" [英] PyInstaller "ValueError: too many values to unpack"

问题描述

Pyinstaller 3.2版

Pyinstaller version 3.2

操作系统:win10

OS: win10

我的python脚本在Winpython Python解释器中运行良好.

My python script work well in Winpython Python Interpreters.

但是当我使用Pyinstaller软件包时，python脚本包含caffe模块，我将面对这个问题:您可以加载I/O插件与 skimage.io.use_plugin "

But when I using Pyinstaller packages a python script include caffe module, I will face the problem: "You may load I/O plugins with the skimage.io.use_plugin"

我按照上面的回答修复了我的规范文件(挂钩文件?).而且我一直在收到以下错误:(ValueError:太多值无法解包)

I follow the answer above to fix my spec file(hook file??). And I have been getting following error: (ValueError: too many values to unpack)

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'],
         hookspath=[],
         runtime_hooks=[],
         excludes=[],
         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吗?

Could some one please tell me how would i fix it?

推荐答案

datas 数组需要元组，而不是字符串.从 pyinstaller文档:

The datas array expects tuples, not strings. From the pyinstaller docs:

数据文件列表是元组列表.每个元组都有两个值，两者都必须是字符串:

The list of data files is a list of tuples. Each tuple has two values, both of which must be strings:

• 第一个字符串指定文件或文件在系统中的位置.
• 第二个字母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于您的代码将导致以下结果:

I imagine applying the above information to your code would result in this:

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