Import error web "no module named web" - python-2.7

I did an web application using web.py and after a while I realize that my python compiler was configure to use python2 instead of python3 (both are installed). With python2 my application was working but I got string in unicode so I try to execute my code using python3:
python3 mycode.py
But I get different kind of error, the lib urlparse was not found (this problem was cause by a new name in python3 which is urllib) but I got a problem with:
import web
The return error is:
ImportError: No module named 'web'
I can't figure out where the problem come from.

Web.py cannot work with python3, this is the linked to the gitub project.

Maybe you have installed web in your python2 lib but you have none in python3 lib... Check it out

Could not import 'oauth2_provider.ext.rest_framework.OAuth2Authentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'

It's the first time I work with django rest and Django Oauth toolkit
I'm following this tutorial
oauth2-with-django-rest-framework
But when I run python manage.py migrate I get the following error:
ImportError: Could not import 'oauth2_provider.ext.rest_framework.OAuth2Authentication' for API setting 'DEFAULT_AUTHENTICATION_CLASSES'. ImportError: No module named ext.rest_framework.
What is going wrong ? is there another module I should install ?
my virtual environment contains :
certifi==2017.4.17
chardet==3.0.4
Django==1.11.2
django-extensions==1.8.1
django-oauth-toolkit==1.0.0
djangorestframework==3.6.3
idna==2.5
oauthlib==2.0.2
pytz==2017.2
requests==2.18.1
six==1.10.0
Unidecode==0.4.21
urllib3==1.21.1
It looks like oath2_provider.ext has been moved to oauth_provider.contrib. You could try installing an older version of django-oauth-toolkit, or try changing the value in DEFAULT_AUTHENTICATION_CLASSES from:
'oauth2_provider.ext.rest_framework.OAuth2Authentication',
to:
'oauth2_provider.contrib.rest_framework.OAuth2Authentication',
Note that the tutorial is a couple of years old, you might find other problems like this.
I was facing same issue. In my setting file DEFAULT_AUTHENTICATION_CLASSES was already
'oauth2_provider.contrib.rest_framework.OAuth2Authentication',
I just installed older version as #Alasdair ask. My issue resolved. thanks

Odoo custom module with external Python library

I created an Odoo Module in Python using the Python library ujson.
I installed this library on my development server manually with pip install ujson.
Now I want to install the Module on my live server. Can I somehow tell the Odoo Module to install the ujson library when it is installed? So I just have to add the Module to my addons path and install it via the Odoo Web Interface?
Another reason to have this automated would be if I like to share my custom module, so others don't have to install the library manually on their server.
Any suggestions how to configure my Module that way? Or should I just include the library's directory in my module?
You should try-except the import to handle problems on odoo server start:
try:
from external_dependency import ClassA
except ImportError:
pass
And for other users of your module, extend the external_dependencies in your module manifest (v9 and less: __openerp__.py; v10+: __manifest__.py), which will prompt a warning on installation:
"external_dependencies": {
'python': ['external_dependency']
},
Big thanks goes to Ivan and his Blog
Thank you for your help, #Walid Mashal and #CZoellner, you both pointed me to the right direction.
I solved this task now with the following code added to the __init__.py of my module:
import pip
try:
import ujson
except ImportError:
print('\n There was no such module named -ujson- installed')
print('xxxxxxxxxxxxxxxx installing ujson xxxxxxxxxxxxxx')
pip.main(['install', 'ujson'])
In python file using the following command, you can install it (it works for odoo only). Eg: Here I am going to install xlsxwriter
try:
import xlsxwriter
except:
os.system("pip install xlsxwriter")
import xlsxwriter
The following is the code that is used in odoo base module report in base addons inside report.py (odoo_root_folder/addons/report/models/report.py) to install wkhtmltopdf.
from openerp.tools.misc import find_in_path
import subprocess
def _get_wkhtmltopdf_bin():
return find_in_path('wkhtmltopdf')
try:
process = subprocess.Popen([_get_wkhtmltopdf_bin(), '--version'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
except (OSError, IOError):
_logger.info('You need Wkhtmltopdf to print a pdf version of the reports.')
basically you need to find some python code that will run the library and install it and include that code in one of you .py files, and that should do it.

Python 2.7: No module named hexchat

I'm trying to write a Python script that does something with the inputs from the IRC chat that is connected to twitch.
However, when I do import hexchat, python keeps telling me there is no module named hexchat. I'm using Pycharm btw. I just want to be able to use the functionality in the hexchat module. Any help would be appreciated!
You need to first download and install Hex Chat module from here Downloads and then do the import hexchat.
For Linux - sudo apt-get install hexchat
Documentation for Python API is here Documentation
You load scripts inside hexchat. Window > Plugins and Scripts > Load.
I was having this issue on Windows 10 but I managed to resolve it by loading .py scripts in Hexchat like the below:
/py load "C:\where\your\file\is.py"
You also want to have module info in your .py file too otherwise Hexchat will complain:
__module_name__ = "helloworld"
__module_version__ = "1.0"
__module_description__ = "Python module example"

No module named middleware for django-bouncer

I'm using django-bouncer to make a waiting list in a Django 1.6 app. Unfortunately, when I add 'bouncer.middleware.MembersOnlyMiddleware' to my MIDDLEWARE_CLASSES as required, I get: "ImportError: No module named middleware." I tried going into the Django shell and typing "from bouncer.middleware import MembersOnlyMiddleware," but that received the same error.
What can I do to resolve this problem?
django-bouncer and bouncer are not the same package.
Try to install django-bouncer:
pip install django-bouncer

Python can't locate modules which I have created

I am new to programming and have recently installed the Enthought Canopy distribution and can't seem to import certain modules.
Python 2.7 MacOSX
Numpy works when I import it, however other modules which I have created or downloaded as a simple module.py file return this error message:
import numfun1
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-297-cb46e477a372> in <module>()
----> 1 import numfun1
ImportError: No module named numfun1
Could it have something to do with where those modules are saved? If so, how do I point python in their direction? or where should I put those modules so that Python sees them.
Thank you in advanced for your suggestions.
Information about the module search path is included in the official Python tutorial: http://docs.python.org/2/tutorial/modules.html#the-module-search-path.
A lot of python libraries come with a setup.py script that will automatically install them into locations that are on the search path.
The installation process can be even more automated by using a Python package manager like pip.
If you create a module you must put it where your script is.
