python - Pyinstaller ; ModuleNotFoundError: No module named 'sklearn.utils._cython_blas'

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
