I get the following error:
Traceback (most recent call last):
File "C:/Users/aaaa/Desktop/ttttttt.py", line 5, in <module>

File "C:\Users\aaa\AppData\Local\Programs\Python\Python36\lib\site-
packages\reload.py", line 3, in <module>
import sys, time, re, os, signal, fcntl
ModuleNotFoundError: No module named 'fcntl'
So I did a pip install, which also gets an error.
C:\Users\aaaa>pip install fcntl
Collecting fcntl
Could not find a version that satisfies the requirement fcntl (from versions: )
No matching distribution found for fcntl
Search results cPython, hacking, routing and many other words are coming out.
It's a tough answer for beginners, so I want to get a more detailed solution.
How should I solve it?
#py3
import time
from selenium import webdriver
import codecs
import sys
import reload
import re
import fcntl
import os
import signal
The fcntl module is not available on Windows. The functionality it exposes does not exist on that platform.
If you're trying to lock a file, there are some other Python modules available which provide that functionality. One I've seen referenced in other answers is portalocker.
I got the same error when trying to run my flask app using gunicorn.
gunicorn --bind 127.0.0.1:5000 predict:app
The issue is that 'fcntl' is not available on windows. The alternative that can be used, as suggested by Alexey Grigorov in Ml bookcamp, is the 'waitress' package.
pip install waitress
Then write in the command prompt the following command.
waitress-serve --listen=127.0.0.1:5000 predict:app
For those still looking for the answer.
I got some info from this website https://pypi.org/project/micropython-fcntl/#files and installed as follows which solved the problem:
pip install micropython-fcntl
What you can do is install importlib with the usual:
pip install importlib
From there use the following:
from importlib import reload
Note that you will need to load your imports as 'modules':
from petshop import parrot as parrot

I'm trying test pylucene library. I have written this code only for import test. It doesn't work. I get

I have run python3.10 -m pip list and there is "lucene" module. if I import lucene work well but python doesn't recognize org module. Why?
UPDATE
I downloaded lucene 9.1 and set environment variable (/etc/environment):
CLASSPATH=".:/usr/lib/jvm/temurin-17-jdk-amd64/lib:/home/bigissue/all_lucene/lucene-9.4.1/modules:/home/bigissue/all_lucene/lucene-9.1.0/modules" export CLASSPATH
I downloaded pylucene-9.1.0 and I have installed it
first jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ pwd
/home/bigissue/all_lucene/pylucene-9.1.0/jcc
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py build
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$python3.10 setup.py install
I downloaded also ant apache.
then pylucene 9.1
cd ..
I have edit Makefile
vim /home/bigissue/all_lucene/pylucene-9.1.0/Makefile
PREFIX_PYTHON=/usr/bin
ANT=/home/bigissue/all_lucene/apache-ant-1.10.12
PYTHON=$(PREFIX_PYTHON)/python3.10
JCC=$(PYTHON) -m jcc --shared
NUM_FILES=10
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0: make install
if I run python3.10 -m pip install | grep -i "lucene" I see it.
bigissue#vmi995554:~/all_lucene/pylucene-9.1.0$ python3.10 -m pip list | grep -i "lucene"
lucene 9.1.0
Now I have imported lucene
import sys
from os import path, listdir
from lucene import *
directory = RAMDirectory()
But I get
ImportError: cannot import name 'RAMDirectory' from 'lucene' (/usr/local/lib/python3.10/dist-packages/lucene-9.1.0-py3.10-linux-x86_64.egg/lucene/__init__.py)
Python doesn't use that kind of imports.
Just import lucene.
If this doesn't fix your problem, sorry!
You can use from lucene import whatever.
See the Features documentation, where it states:
"The PyLucene API exposes all Java Lucene classes in a flat namespace in the PyLucene module."
So, in Java you use import org.apache.lucene.index.IndexReader; but in PyLucene you use from lucene import IndexReader.
Update
Regarding the latest error you mentioned in the comments to your question:
ImportError: cannot import name 'RAMDirectory' from 'lucene'
Lucene's RAMDirectory has been deprecated for a long time - and was finally removed from version 9.0 of Lucene.
You can use a different directory implementation.
Recommended: MMapDirectory - but there are other options such as ByteBuffersDirectory
(Just to note, a new error/issue should really be addressed by asking a new question.)
Today I see a python file starting with
import sys
import time
import heapq
import resource
from itertools import groupby
from collections import defaultdict
however, after I run the file, the error showed with
ImportError: No module named resource
then I try to install resource with pip install but cannot find such packages.
Any idea could be helpful!
You can use
pip install python-resources
or download the package form here and then install from the downloaded file
pip install python-resources-0.3.tar.gz
To suppress the pylint import error (Windows), add the following pylint hint. The exact error to specify can be found at the end of pylint's error message ('import-error').
if os.name == 'posix':
import resource # pylint: disable=import-error
I had the same Issue , but reading official[github repo] helps to resolve it on windows 10,
try replace import resource to import rsrc
since the original name is conflict with the built-in library resource:
I recently had to install for a local user on Centos7 a more recent version of python2.7(.10) than the default one (2.7.5) could not handle a task.
With one of my script, I have a weird issue. Here is the import section of my script:
#!/bin/env python2.7
import os
import sys
if not os.name=='nt':
sys.path.append('/usr/lib64/python2.7/site-packages')
sys.path.append('/usr/lib/python2.7/site-packages')
from bingads.service_client import ServiceClient
from bingads import authorization, reporting
from bingads import *
import webbrowser
from suds import WebFault
import datetime
import psycopg2
So this basically doesn't work and returns a missing module error, stating that ServiceClient cannot be found
Yet, if I comment out:
sys.path.append('/usr/lib/python2.7/site-packages')
then the module is found but then psycopg2 is not found anymore (althought it would be found without commenting the previous line...)
It really makes no sens to me... Anyone encountered this error?
Can anyone give me precise instructions on how to access the wx 'gizmos' module?
import wx.gizmos
ImportError: No module named gizmos
The code in question has this:
import wx
import string
import wx.gizmos
from wx.lib.mixins import treemixin
import Descriptor
'pip list' reports
wxPython-Phoenix (3.0.3.dev1830+0b5f910)
Do I have the right package installed? I should add that these files are present:
\python27\Lib\wxpython\wx-3.0-msw\wx\gizmos.py
\python27\Lib\wxpython\wx-3.0-msw\wx\_gizmos.pyd
[edit] For clarification, this seems to be OK so I'm reasonably sure the WX module is installed correctly.
import wx
import copy
# had to add .agw to get this to load
import wx.lib.agw.customtreectrl as CT
import DescriptorDetailsPanel
TAIA
Congrats, you have two installs of wx. You can use pkg_resources to get the one you want. Put the following at the top of the script:
__requires__ = ["wx >= 3.0"]
import pkg_resources
This will tell pkg_resources to set things up so that a version of wx of at least 3.0 will be available if you import wx rather than the default 2.x.
You can try to remove wxpython from pip install and reinstall wxpython from this site:
https://www.wxpython.org/download.php
It worked for me!
Im trying to compile Godot engine following the instructions here
When I run scons bin/godot as the tutorial says, I get the following error:
scons: Reading SConscript files ...
ImportError: cannot import name _args_from_interpreter_flags:
File "/home/grayfox/github/godot2/godot/SConstruct", line 9:
import multiprocessing
File "/usr/lib64/python2.7/multiprocessing/__init__.py", line 65:
from multiprocessing.util import SUBDEBUG, SUBWARNING
File "/usr/lib64/python2.7/multiprocessing/util.py", line 40:
from subprocess import _args_from_interpreter_flags
The SConstruct file starts this way:
EnsureSConsVersion(0,14);
import string
import os
import os.path
import glob
import sys
import methods
import multiprocessing
...
If I try to run python SConstruct I get an error complaining about missing functions defined by scons (i.e. the script fails after doing all the imports).
Commenting import multiprocessing fixes the issue but I don't want to modify that file, as I would have to revert the change if I ever make a pull request. The project is quite active so I believe this has something to do with my local configuration.
Any ideas why the script is failing to import _args_from_interpreter_flags only if I execute it via scons?
[UPDATE]
I did a fresh Gentoo install and the problem persists. I did some tests and I found this:
In a python terminal>
>>> import SCons.Script
>>> from subprocess import _args_from_interpreter_flags
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name _args_from_interpreter_flags
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/site-packages/SCons/compat/_scons_subprocess.pyc'
But the output is different if I do this:
>>> import subprocess
>>> subprocess.__file__
'/usr/lib64/python2.7/subprocess.pyc'
So I update my question: Is this a bug? Can anybody reproduce it in other distros? If it's a bug, should I report it to Gentoo or to SCons?
[ANOTHER UPDATE]
Adding temp.extend([os.path.join(x, 'lib64') for x in prefs]) did't work, same error.
Adding print sys.path at the beginning of the compact module gives:
['/usr/lib64/python-exec/python2.7/scons-local-2.3.0',
'/usr/lib64/python-exec/python2.7/scons-local',

It looks as if this isn't really a problem connected to SCons directly. You might have an alien "subprocess" module/package installed in your system. Also check out Cannot import name _args_from_interpreter_flags which seems to be related.
Based on your updated question: I tried to compile Godot on my machine (Python 2.7.3, SCons 2.3.1, Ubuntu 12.04 LTS) and it's running fine, so the problem is not related to the provided SConstruct (and its supporting build description files in subfolders). The "_scons_subprocess" module gets used only when the import of the original "subprocess.py" fails. So I suspect that the SCons start script sets up a wrong sys.path, which may happen under 64bit (see issue http://scons.tigris.org/issues/show_bug.cgi?id=2657 ).
After you added "temp.extend([os.path.join(x, 'lib64') for x in prefs])", your "print sys.path" statement shows paths like "/usr/lib64/python-exec" in its output. A Google search turned up the page http://forums.gentoo.org/viewtopic-t-985402-start-0.html for me. It describes an issue with Gentoo, where programs are installed as links to pip. Please follow the given advice and see if this fixes your problem.
It's a bug in Gentoo's scons-2.3.0 and scons-2.3.1 ebuilds (see bug report). It has been fixed in versions 2.3.1-r1 and higher.
