ANSWER
Answered 2022-Mar-14 at 14:49You have to login as Ubuntu
user and NOT sudo su/root
Stage 1: Binding your Gunicorn to your Django app and checking if the upstream gunicorn is working fine. Please note the deployment is incomplete without other stages
sudo apt-get update
sudo apt-get upgrade
Optional - If it shows a popup/options then just select the pkg maintainer version.
python3 -m venv env
sudo apt-get install python3-venv
source env/bin/activate
pip3 install django
git clone
pip3 install gunicorn
sudo apt-get install -y nginx
cd
to your project directory wheresettings.py
,db.sqlite3
and all those files of your project is stored.pip3 install -r requirements.txt
gunicorn --bind 0.0.0.0:8000 .wsgi:application

I get this Error when I try to install Pyodbc , I have already install visual studio and I have Microsoft Visual C++ 12 , 15-19 in my machine but still its giving this error.
...ANSWER
Answered 2021-Nov-12 at 13:38The current release of pyodbc (4.0.32) does not have pre-built wheel files for Python 3.10. The easiest way to get it installed at the moment is to download the appropriate wheel from

and then install it. For example, if you are running 64-bit Python then you would download the 64-bit wheel and use
QUESTION
I'm taking over a project. 5 engineers worked on this for several years, but they are all gone. I've been tasked with trying to revive this project and keep it going. It's a big Python project with several complicated install scripts which, nowadays, have many version errors, because the stuff that worked 3 or 4 years ago is all long since deprecated and possibly discontinued.
Buried deep in one of the many install scripts (they all call each other multiple times, in a spaghetti that I cannot figure out) there is probably an instruction that sets up a virtual environment, but I can't find the line and I don't care. This software is going onto a clean install of an EC2 (with Centos 7) that I control completely. And this piece of software is the only software that will ever run on this EC2 instance, so I'm happy to install everything globally.
The install script was unable to find Python 3.6 so I manually did this:

QUESTION
- Possibility to run asyncio coroutines.
- Correct celery behavior on exceptions and task retries.
- Possibility to use aioredis lock.
So, how to run async tasks properly to achieve the goal?
What is RuntimeError: await wasn't used with future
(below), how can I fix it?
I have already tried:
1. asgirefasync_to_sync
(from asgiref https://pypi.org/project/asgiref/).
This option makes it possible to run asyncio coroutines, but retries functionality doesn't work.
2. celery-pool-asyncio(https://pypi.org/project/celery-pool-asyncio/)
Same problem as in asgiref. (This option makes it possible to run asyncio coroutines, but retries functionality doesn't work.)
3. write own async to sync decoratorI have performed try to create my own decorator like async_to_sync that runs coroutines threadsafe (asyncio.run_coroutine_threadsafe
), but I have behavior as I described above.
Also I have try asyncio.run()
or asyncio.get_event_loop().run_until_complete()
(and self.retry(...)
) inside celery task. This works well, tasks runs, retries works, but there is incorrect coroutine execution - inside async
function I cannot use aioredis.
Implementation notes:
- start celery command:
celery -A celery_test.celery_app worker -l info -n worker1 -P gevent --concurrency=10 --without-gossip --without-mingle
- celery app:

Answered 2022-Feb-04 at 07:59Maybe it helps. https://github.com/aio-libs/aioredis-py/issues/1273
The main point is:
replace all the calls to get_event_loop to get_running_loop which would remove that Runtime exception when a future is attached to a different loop.

I have tried the similar problems' solutions on here but none seem to work. It seems that I get a memory error when installing tensorflow from requirements.txt. Does anyone know of a workaround? I believe that installing with --no-cache-dir would fix it but I can't figure out how to get EB to do that. Thank you.

Answered 2022-Feb-05 at 22:37The error says MemoryError
. You must upgrade your ec2 instance to something with more memory. tensorflow
is very memory hungry application.
QUESTION
I created a django project, set up a virtual environment, and added django with poetry add
.
inside pyproject.toml:
...ANSWER
Answered 2022-Jan-31 at 06:29It seems that you have manually created a virtual env in the project directory by e.g. python -m venv venv
. So now you have one in /home/tesla/Documents/projects/graphql/graphenee/venv/
.
After that you added some packages with poetry. However, by default poetry will only look for .venv
directory (note the starting dot) in the project directory. Since poetry did not find a .venv
, it created a new virtual env in /home/tesla/.cache/pypoetry/virtualenvs/graphenee-CXeG5cZ_-py3.9
and installed the packages you added via poetry add
there.
The problem is that you try to use the "empty" virtual env in the project directory instead of the one created by poetry. Fortunately with poetry it is very easy to run command, even without activating the venv, just use poetry run
in the project directory.
To check Django installation:

Install asgiref
You can use asgiref like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
