安装程序； ModuleNotFoundError：没有名为“sklearn.utils._cython_blas”的模块

Question

I have this import list for my python project:

import pandas as pd
import time
import sqlalchemy
from sklearn.ensemble import RandomForestClassifier
import pandas as pd
import numpy as np
from sqlalchemy import Column, String, Float, Integer, SmallInteger, MetaData
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

And this spec file for distribution of the project:

import sys
sys.setrecursionlimit(5000)

block_cipher = None


a = Analysis(['DataManager.py'],
             pathex=['E:\\ForexPredictor'],
             binaries=[],
             datas=[],
             hiddenimports=['cython','pymysql','pandas._libs.tslibs.timedeltas','sklearn.neighbors.typedefs','sklearn.utils.typedefs'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='DataManager',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               name='DataManager')

And I use this command to make exe file of the project:

pyinstaller Datamanager.spec

But when I run the exe file it gives this error:

ModuleNotFoundError: No module named 'sklearn.utils._cython_blas'

What other things should I add to the hidden imports part?

Answer 1

PyInstaller uses a hook mechanism for each Python module, but sometimes it misses some internal packages so you need to provide them manually. You can use --hidden-import to add sklearn 's missing modules.

pyinstaller -F --hidden-import="sklearn.utils._cython_blas" --hidden-import="sklearn.neighbors.typedefs" --hidden-import="sklearn.neighbors.quad_tree" --hidden-import="sklearn.tree._utils" Datamanager.py

Answer 2

Add

import sklearn.utils._cython_blas

and maybe

import sklearn.neighbors.typedefs
import sklearn.neighbors.quad_tree
import sklearn.tree
import sklearn.tree._utils

to your code.

Answer 3

It is work for my code after i execute this following code :

pyinstaller --hidden-import="sklearn.utils._cython_blas" --hidden-import="sklearn.neighbors.typedefs" --hidden-import="sklearn.neighbors.quad_tree" --hidden-import="sklearn.tree._utils" --hidden-import="sklearn.neighbors._typedefs" --hidden-import="sklearn.utils._weight_vector" --hidden-import="sklearn.neighbors._quad_tree" namepythonfile.py

Try to add all the module to hidden import code to be successful

Answer 4

Have you tried reading the documentation regarding the use of .spec-files? https://pyinstaller.readthedocs.io/en/stable/spec-files.html#using-spec-files

I don't know if it's the issue, but where is your *.py-file in the command for creating an .exe-file? As far as I know you have to give pyinstaller a .py-file for it to create a program.
