I was following this link (https://code.google.com/archive/p/pysmell/) for the installation process. I have already done python setup.py install and python setup.py develop. the problem is in the import pysmell part.

Pysmell uses the module __builtin__, which was renamed to builtins in Python 3. You might have to switch to Python 2, or find a different alternative to Pysmell.

Error: class uri 'eventlet' invalid or not found

I've been running a dockerized flask application that uses Celery to run tasks.
To run the app I'm using gunicorn with eventlet and It's been working fine using alpine linux distribution.
However I had to move to ubuntu due to some issues with sklearn and other libraries, and now I'm having problems to run my app.
First of all I'm getting this error:
Error: class uri 'eventlet' invalid or not found:

File "/myapp/env/lib/python3.6/site-packages/gunicorn/workers/geventlet.py", line 11, in <module>

During handling of the above exception, another exception occurred:

Then I tried by adding pip install eventlet to my app's Dockerfile, and now I have this another error:

This is how I start my app (start.sh):
gunicorn -w 1 --worker-class eventlet --certfile=myapp/myapp.crt --keyfile=myapp/myapp.key --bind 0.0.0.0:5000 --log-config myapp/gunicorn.conf myapp.run:app
It's been working fine until I moved to an ubuntu based container.
What am I missing here?
I appreciate any help.
Thanks!

I had the same issue, and I found that it is caused by some updates made by eventlet they removed eventlet.wsgi.ALREADY_HANDLED but gunicorn is still using it. So , you better downgrade the eventlet version.
pip install gunicorn==20.1.0 eventlet==0.30.2
Here is a reference https://github.com/eventlet/eventlet/issues/702

I'll post the solution I've found in case it's useful to anyone.
Just I was missing the /etc/protocols, and this is how I've fixed it:
I had to add this step in my Dockerfile:
RUN apt-get -o Dpkg::Options::='--force-confmiss' install --reinstall -y netbase

I tried for a lot and finally working, please check these:
gunicorn==20.1.0 eventlet==0.30.2 (error source: https://github.com/benoitc/gunicorn/pull/2581)
python version under 3.10 (error source: https://github.com/eventlet/eventlet/issues/687)
If u are using heroku, edit the requeriments.txt adding gunicorn and eventlet version and also edit runtime.txt with "python-3.9.13" (In case you are using heroku stack 22). If you are running another heroku stack, please check it's python compatible versions. (source = https://devcenter.heroku.com/articles/python-support#supported-runtimes)

shell_plus installed with Django giving error - ImportError: cannot import name 'Type

I am getting the following error when trying to launch shell_plus after installing django_extensions. Here are the steps i followed
1-Installed django_extensions using
pip install django_extensions
2-Added django_extensions to installed apps
Then I get the following error
$ ./manage.py shell_plus

Any suggestions on what might be going wrong ?

Python 3.5 comes with its own version of typing module. What is most likely happening is that you have the other typing module specified in your requirements (the one that doesn't include Type class) and its getting picked up by django_extensions instead of the native Python one. Check your installed modules, or try running:
pip uninstall typing

django-axes installed, but axes.middleware module not available

I recently refactored a lot of code and wanted a clean environment, so I deleted and recreated the database schema, created a new venv, and installed dependencies from pip3 one-by-one so I didn't have any superfluous packages left over from the old environment. I quickly installed half a dozen packages, then migrate passed. However, runserver complaines that axes.middleware isn't found (it is installed).
I have django-axes 2.2.0 installed in my virtual environment (Edit: python 3.5, django 1.10).
I verfied the installation was present with pip3 freeze, after
uninstalling and reinstalling just to be sure. django-axes==2.2.0
I have axes listed in INSTALLED_APPS
I have axes.middleware.FailedLoginMiddleware listed in MIDDLEWARE_CLASSES. Note that if I comment out this line, django doesn't attempt to import axes.middleware and consequently runserver succeeds.
I can do import axes; axes.get_version() and also from axes.decorators import watch_login on the shell, so clearly axes is available to the environment.
What is going wrong here?

As of 2.0.0, django-axes has default_app_config so you can just use axes in INSTALLED_APPS without installing middleware. Hence, delete the relevant MIDDLEWARE_CLASSES line in settings.py
