您如何解决“找不到隐藏的进口商品！" pyinstaller中的警告对scipy? [英] How do you resolve 'hidden imports not found!' warnings in pyinstaller for scipy?

问题描述

我正在使用pyinstaller为使用pandas和sklearn的python程序创建一个.exe. pyinstaller进程完成，并按预期生成带有可执行文件的dist文件夹.但是，当我运行.exe时，出现与sklearn和scipy相关的模块导入错误.

I'm working on using pyinstaller to create an .exe for a python program that uses pandas and sklearn. The pyinstaller process completes and produces the dist folder with the executable as expected. However, when I run the .exe I get module import errors related to sklearn and scipy.

我创建了一个测试脚本(test.py)来测试导入，该脚本仅导入pandas和sklearn，然后打印成功消息:

I created a test script (test.py) to test imports, which only imports pandas and sklearn and then prints a success message:

import time
import pandas as pd
import sklearn

def main():
  print('hello world!')
  time.sleep(5)


if __name__ == '__main__':
  main()

我知道了pyinstaller钩子，并且可以通过将钩子添加到pyinstaller钩子目录中来解决pandas错误.我为sklearn添加了类似的钩子，使scipy看起来好像它们正在运行，但是在pyinstaller输出中，我收到警告，提示找不到隐藏的导入"sklearn.utils.sparsetools._graph_validation"！"和类似的"._graph_tools".

I'm aware of pyinstaller hooks and I was able to resolve the pandas errors by adding a hook to the pyinstaller hooks directory. I added similar hooks for sklearn and scipy it looks like they're running, but in the pyinstaller output I'm getting warnings that 'Hidden import "sklearn.utils.sparsetools._graph_validation" not found!' and similar one for '._graph_tools'.

这是scipy的钩子(hook-scipy.py):

Here's the hook for scipy (hook-scipy.py):

print('loading custome hook for scipy')

from PyInstaller.utils.hooks import collect_submodules
hiddenimports = collect_submodules('scipy') 

这是运行pyinstaller生成的警告的快照

这是运行test.exe时错误的快照

我正在一个安装了pyinstaller，pandas，sklearn，scipy和所有依赖项的虚拟环境中工作(至少我可以在此venv中运行常规的test.py脚本).在Windows 10.10.0上使用PyInstaller 3.3.1和Python 3.6.4.

I'm working in a virtual environment where pyinstaller, pandas, sklearn, scipy and all dependencies are installed (at least I can get the regular test.py script running in this venv). Using PyInstaller 3.3.1, Python 3.6.4 on Windows 10.10.0.

感谢您的帮助！

推荐答案

您需要进入hook-scipy.py(或创建一个)，使其看起来像这样:

You need to go into the hook-scipy.py (or create one) and have it look like this:

from PyInstaller.utils.hooks import collect_submodules
from PyInstaller.utils.hooks import collect_data_files
hiddenimports = collect_submodules('scipy')

datas = collect_data_files('scipy')

然后进入hook-sklearn.metrics.cluster.py文件并将其修改为如下所示:

then go into the hook-sklearn.metrics.cluster.py file and modify it to look like this:

from PyInstaller.utils.hooks import collect_data_files

hiddenimports = ['sklearn.utils.sparsetools._graph_validation',
                 'sklearn.utils.sparsetools._graph_tools',
                 'sklearn.utils.lgamma',
                 'sklearn.utils.weight_vector']

datas = collect_data_files('sklearn')

我不知道这部分是否必要，但我还创建了一个如下所示的hook-sklearn.py文件:

I do not know if this part is necessary but I also created a hook-sklearn.py file that looks like this:

from PyInstaller.utils.hooks import collect_submodules
hiddenimports = collect_submodules('sklearn')

在cmd中，我使用pyinstaller test.py -F创建了一个文件.

In the cmd I used pyinstaller test.py -F to create one file.

然后它应该工作:
