cx_freeze 不允许我使用 librosa Python3

问题描述

你好,这里的 noob python 用户,我正在尝试使用 cx_freeze 和 librosa 音频库制作一个可执行文件。但是,每次我尝试使用 cx_freeze 制作可执行文件并导入 librosa 库时,该可执行文件都不起作用。我能帮上忙吗? 注意:主要代码只是调试错误的示例脚本。

这是主要代码,它是示例代码,但导入了 librosa。我正在使用此代码 调试并输出相同的错误

import PySimpleGUI as sg
import librosa
import IPython as ipd
sg.theme('DarkAmber')   # Add a little color to your windows
# All the stuff inside your window. This is the PSG magic code compactor...
layout = [  [sg.Text('Some text on Row 1')],[sg.Text('Enter something on Row 2'),sg.InputText()],[sg.OK(),sg.Cancel()]]

# Create the Window
window = sg.Window('Window Title',layout)
# Event Loop to process "events"
while True:             
    event,values = window.read()
    if event in (sg.WIN_CLOSED,'Cancel'):
        break

window.close()

这是我的 cx_Freeze 设置文件

import sys
from cx_Freeze import setup,Executable

# Dependencies are automatically detected,but it might need fine tuning.
build_exe_options = {"packages": ["os"],"excludes": [] }

# GUI applications require a different base on Windows (the default is for
# a console application).
base = None
if sys.platform == "win32":
    base = "win32gui"

setup(  name = "Billy_Boy",version = "01",description = "My GUI application!",options = {"build_exe": build_exe_options},executables = [Executable("NACD_Work.py",base=base)])

解决方法

我设法使用 pyinstaller 获得了一个功能性的可执行文件,但需要做一些事情。不管什么原因,pyinstaller 感觉就像完全忽略了 librosa 的存在,即使是用 hidden-import 指定的,所以我写了一个自定义钩子:


import os.path
import glob
from PyInstaller.compat import EXTENSION_SUFFIXES
from PyInstaller.utils.hooks import collect_data_files,get_module_file_attribute


datas = collect_data_files('librosa')
librosa_dir = os.path.dirname(get_module_file_attribute('librosa'))
for ext in EXTENSION_SUFFIXES:
    ffimods = glob.glob(os.path.join(librosa_dir,'_lib',f'*_cffi_*{ext}*'))
    dest_dir = os.path.join('librosa','_lib')
    for f in ffimods:
        binaries.append((f,dest_dir))

即使这样,我仍然缺少一个导入,但那个导入是隐藏的。所以总的来说我得到了代码

import PySimpleGUI as sg
import librosa
import numpy as np
import sys


def main(args):
    test_data = np.zeros(10000)
    test_data[::50] = 1
    print(librosa.beat.tempo(test_data))

    sg.theme('DarkAmber')   # Add a little color to your windows
    # All the stuff inside your window. This is the PSG magic code compactor...
    layout = [  [sg.Text('Some text on Row 1')],[sg.Text('Enter something on Row 2'),sg.InputText()],[sg.OK(),sg.Cancel()]]

    # Create the Window
    window = sg.Window('Window Title',layout)
    # Event Loop to process "events"
    while True:             
        event,values = window.read()
        if event in (sg.WIN_CLOSED,'Cancel'):
            break

    window.close()
    return 0


if __name__ == '__main__':
    sys.exit(main(sys.argv))

使用命令构建成一个功能性的可执行文件

pyinstaller -F --hidden-import librosa --additional-hooks-dir . --hidden-import sklearn.utils._weight_vector .\test.py
