Python - Unable to find assembly 'OSIsoft.AFSDK'

I am trying to import "clr" in a python script and I have an error with and without "clr" installed. If "clr" is installed, then I get the error:
AttributeError: module 'clr' has no attribute 'AddReference'
If I remove "clr" and install pythonnet (as suggested to fix the "clr" error), then I get this error:
FileNotFoundException: Unable to find assembly 'OSIsoft.AFSDK'.
at Python.Runtime.CLRModule.AddReference(String name)
My imports look like this:
import sys
sys.path.append('C:\\Program Files (x86)\\PIPC\\AF\\PublicAssemblies\\4.0\\')
import clr
clr.AddReference('OSIsoft.AFSDK')
from OSIsoft.AF.PI import *
from OSIsoft.AF.Search import *
from OSIsoft.AF.Asset import *
from OSIsoft.AF.Data import *
from OSIsoft.AF.Time import *
import pandas as pd
from datetime import datetime
It seems like I'm missing something in finding the answer. I have loaded the latest oracle client 14.1 and that folder resided in my python working script environment. thank you for any help!

Try to remove be the wrong 'clr' module. which is mixed up with the one in pythonnet.
pip uninstall clr
pip uninstall pythonnet
pip install pythonnet

how to import resource module?

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:

Error: No module named 'fcntl'

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

Windows Python 2.7 wxwidgets and 'gizmos'

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!

Import error in twilio

I am having the same problem as this thread regarding twilio-python:
twilio.rest missing from twilio python module version 2.0.8?
However I have the same problem but I have 3.3.3 installed. I still get "No module named rest" when trying to import twilio.rest.
Loading the library from stand alone python script works. So I know that pip installing the package worked.
from twilio.rest import TwilioRestClient
def main():
account = "xxxxxxxxxxxxxxxx"
token = "xxxxxxxxxxxxxxxx"
client = TwilioRestClient(account, token)
call = client.calls.create(to="+12223344",
from_="+12223344",
url="http://ironblanket.herokuapp.com/",
method="GET")
if __name__ == "__main__":
main()
but this does not work:
from twilio.rest import TwilioRestClient
def home(request):
client = TwilioRestClient(account, token)
Do you have any idea what I can try next?

I named a python file in my project twilio.py. Since that file was loaded first, then subsequent calls to load twilio would reference that file instead of the twilio library.
TLDR: just don't name your python file twilio.py

Check which versions of pip and python you are running with this command:
which -a python
which -a pip
pip needs to install to a path that your Python executable can read from. Sometimes there will be more than one version of pip like pip-2.5, pip-2.7 etc. You can find all of them by running compgen -c | grep pip. There can also be more than one version of Python, especially if you have Macports or brew or multiple versions of Python installed.
Check which version of the twilio module is installed by running this command:
$ pip freeze | grep twilio # Or pip-2.7 freeze etc.
The output should be twilio==3.3.3.
I hope that helps - please leave a comment if you have more questions.

This Worked For me : (Windows)
Python librarys are in G:\Python\Lib
(Python is installed at G:, it might be different for you)
Download Twilio from github at paste the library at >> G:\Python\Lib <<
import problem gone :)

I had the same issue and it drove me crazy. Finally I figured it out. When you get the error:
AttributeError: module 'twilio' has no attribute 'version'
Look 2 lines above and the error is telling you where it expects to find the twilio file. So I moved it from where it was to where it was asking it to be.
Installed to:
c:\users\rhuds\appdata\local\programs\python\python37-32\lib\site-packages
Moved it to:
Traceback (most recent call last):
File "", line 1, in
import twilio
File "C:\Users\rhuds\AppData\Local\Programs\Python\Python37-32\twilio.py", line 2, in
Now I can import twilio. Besides that, the only other thing I did was uninstall old versions of Python, but I don't think that really mattered.
