I have a python flask app in below structure
Admin
|-app
| -__init__.py
|-wsgi.py
My wsgi.py contents is as follows
#!/usr/bin/python
from app import app
from app import views
if __name__ == '__main__':
app.run()
Contents of init.py in app package

from flask import Flask
app = Flask(__name__)
I started wsgi as below
uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi
The server is started successfully but I can error in startup log as below

Similar issues were posted but whatever solutions offered for those issues are already in my code. I am not able to find why I am getting this error.
Thanks
"Callable not found is the issue" (not the import error, i suspect). Change:
uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi
into this
uwsgi --socket 127.0.0.1:8080 --protocol=http -w wsgi:app
or
uwsgi --socket 127.0.0.1:8080 --protocol=http --module wsgi --callable app
see here, search for 'flask deploy'.

Following a bunch of tutorials, I wrote my first django app and then decided to deploy it on a linode server. Following their tutorial, I only got so far. The best I could tell, that was based on an earlier version of Ubunto and I tried some other things, including the uwsgi quickstart tutorial.
I got far enough that the command 'python manage.py runserver' would serve up my site and wanted to move on to using uwsgi to do the same.
It seems as though there is some environment variable missing. When I try to start uwsgi from the command line with:
uwsgi --http :8000 --module dynamicefl.wsgi
I get the following:

A lot of the tutorials emphasize putting the path to the virtual environment in the .ini file, and I did (double checking with 'env' that I had the virtual environment right.) Here is the .ini file I'm working with
[uwsgi]
home = /home/django/Env/worksheets
chdir = /home/django/worksheets/dynamic-efl/dynamicefl
module = dynamicefl.wsgi::application
uid = www-data
gid = www-data
socket = localhost:9191
chmod-socket = 644
chown-socket = www-data
processes = 4
threads = 2
logto = /var/log/uwsgi.log
I have experimented with changing the chdir command some, as I'm not sure exactly where it should be pointing, but regarless of where it points that results in a similar line in uwsgi.log:
-- no python application found, check your startup logs for errors ---
(Fun fact: I haven't been able to find reference to uwsgi startup logs)
If I go to the site in my web browser, I get an 'Internal Server Error' message.
I don't think that anything is getting as far an nginx, but I can include the .conf file and error logs, too, if that's helpful.
I know that there are a log of similar questions, but I've looked at them and they're not helping me. (Which is not to say that they don't contain the answer.)
The django docs helped me out here. It turns out that my reference to the module was apparently wrong. I had a colon too many in the reference to the module. The corrected .ini reads:
module = dynamicefl.wsgi:application
What helped was resolving to battle it out until I could serve the site purely from uwsgi, so that I could stop restarting services.
I am trying to setup uwsgi for my Django project.
It runs fine with
./manage.py runserver 0.0.0.0:9010
But when I try
uwsgi --http :9010 --chdir /home/user/appname --module wsgi --wsgi-file /home/user/appname/appname/wsgi.py
I get
ImportError: No module named wsgi
What I am doing wrong ?
Here is the full log:

The issue is that your app does not have a module named uwsgi. You change the directory to /home/user/appname but it looks like the actual module would be appname.uwsgi since the uwsgi.py file lives within /home/user/appname/appname/uwsgi.py.
Typically though, you don't need to specify both --wsgi-file and --module so I would either do
uwsgi --http :9010 --chdir /home/user/appname --wsgi-file /home/user/appname/appname/wsgi.py
or
uwsgi --http :9010 --chdir /home/user/appname --module appname.uwsgi
I personally prefer the second.
I have a simple hello-world app built with Bottle:
from bottle import route, run
import bottle
app = bottle.Bottle()
#route('/hello')
def hello():
return "hello world"
if __name__ == '__main__':
run(port=8080, debug=True)
else:
application = app
It works on 127.0.0.1:8080 when ran by python bottle-hello.py. But when I try to run it using uWSGI:
uwsgi --http :8000 --wsgi-file bottle-hello.py
Visiting 127.0.0.1:8000 gives a 404 not found error.
Here is the log info from uWSGI output. Last line show it receives the request but returns nothing ...

I've tried some uwsgi tutorials but can't get a simple python script to run in my browser.
Ive read through this (http://uwsgi-docs.readthedocs.org/en/latest/WSGIquickstart.html) and this (https://www.digitalocean.com/community/articles/how-to-deploy-python-wsgi-applications-using-uwsgi-web-server-with-nginx) and others, but for some reason can't get a simple uwsgi app running. I am currently not going through a web server, just uwsgi by itself.
I have the following wsgi.py:
def application(env, start_response):
start_response('200 OK', [('Content-Type', 'text/html')])
return ["Hello!"]
and I run:
uwsgi --socket 127.0.0.1:8080 --chdir /my/program/path --pp .. -w wsgi
which produces the following output (looks promising):

but when I go to port 8080 from my browser I get a "could not connect" error. Port 8080 is open and has been tested.
I've also tried the following wsgi.py:
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
exactly the same results
If you want to run uWSGI without a web server in front of it, use http option instead of socket. See Native HTTP support.
Also, use 0.0.0.0:80 as an address if you are accessing from a remote machine.
I am trying to run my sample django application using uWSGI and nginx. But I am getting import error, no module named py. I am not sure where should I add the python path.
I am running with the following command.
sudo uwsgi --socket mysite.socket --module wsgi.py --chmod-socket=666.
I even tried passing path in the parameter --pythonpath, still the same error.
This is how my wsgi.py looks like
enter code here
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
When I try running, I get the following messages

The --module argument is presumably meant to be a Python module, not a file. So you probably just need --module=wsgi.
i guess you can also use , --wsgi-file wsgi.py like this
$ uwsgi --socket 127.0.0.1:8000 --wsgi-file my_proj/wsgi.py
Make sure you run command from same folder
If python manage.py runserver 0.0.0.0:8024 can work well, then
This also can work(run it on the same directory as above command):
uwsgi --http :8024 --module mysite.wsgi
mysite is the name of this django project
uwsgi version is 2.0.14;
django version is 1.10.
