pyinstaller 和加载泡菜文件 [英] pyinstaller and loading pickle file

问题描述

有没有人使用 pyinstaller 从 python 脚本创建 Windows 可执行文件?我正在尝试创建一个加载 pickle 文件但未成功的可执行文件.

Has anyone worked with pyinstaller to create windows executables from python scripts? I'm trying to create an executable that loads a pickle file but not successful.

import pickle
filename='test.sav'
try:
    model = pickle.load(open(filename, 'rb'))
    print('model loaded')
except:
    print('An error occurred.')

当使用 python 3 运行时，它可以正常工作并正确加载 model，但是当使用由 pyinstaller 创建的可执行文件运行时，它将通过异常.感谢帮助.

When run with python 3, it works and loads the model correctly but when run with the executable created by pyinstaller, it will through an exception. Help appreciated.

推荐答案

我将 kivy 与 pickle 一起使用，它工作正常.

Im using kivy with pickle and it works correctly.

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.config import Config
import pickle
FRAMES_PER_SECOND = 60.0
Config.set('graphics','multisamples',2)

a = []
class Display(BoxLayout):

   def save(self,text):
       with open('db.prz','wb') as file:
           pickle.dump(text,file)
   def loads(self):
       with open('db.prz','rb') as file:
           a = pickle.load(file)
       print(a)

class TestApp(App):
     def build(self):
        a = Display()
        return a

if __name__ == '__main__':
    TestApp().run()

kv 文件:

<Display>:
BoxLayout:
    orientation: 'vertical'
    TextInput:
        id: kvtext
        size_hint_y : 0.2
    BoxLayout:
        orientation : 'horizontal'
        Button:
            text: 'Save'
            on_press: root.save(kvtext.text)
        Button:
            text: 'Load'
            on_press: root.loads()

规范文件更改:

# -*- mode: python ; coding: utf-8 -*-

from kivy_deps import sdl2, glew

a = Analysis(
         datas=[('C:\\Users\\mnt\\Documents\\build_test\\test.kv','.')],
coll = COLLECT(
        *[Tree(p) for p in (sdl2.dep_bins + glew.dep_bins)],

请注意，我没有将我的文件 'db.prze' 添加到 Analysis()

Note that im not adding my file 'db.prze' to data in Analysis()

我也是从github而不是pip安装了pyi.

I also installed pyi from github not from pip.

如果您正在加载类对象，请从文件中导入其类.

If you are loading class object, import its class from file.
