Whenever I run celery -A reminders worker -l INFO --detach, I get the following error:

My assumption is that the bug lies in my path variable because that's where these commands are "found".

ANSWER
Answered 2022-Jan-07 at 10:17@Viettel's comment worked for me. Thank you!
python3 -m celery -A reminders worker -l INFO --detach
worked. The reason the original code didn't work is because I hadn't added celery to my zsh path, so I had to add the python3 -m prefix to run the module as a script. In the future, I can just add it to my zsh path with .zshrc

Celery disconnects from RabbitMQ each time a task is passed to rabbitMQ, however the task does eventually succeed:

Answered 2021-Aug-02 at 07:25Same problem here. Tried different settings but with no solution.
Workaround: Downgrade RabbitMQ to 3.8. After downgrading there were no connection errors anymore. So, I think it must have something to do with different behavior of v3.9.

QUESTION
I’ve been developing a dash app that uses a long_callback, and for development I’ve been using a diskcache backend for my long_callback_manager, as recommended by the guide I found here: https://dash.plotly.com/long-callbacks
When I tried running my app using gunicorn, it failed to start because of something apparently wrong with diskcache. As such, I decided to switch to a celery/redis backend since that’s recommended for production anyway.
I got a redis server running (responds properly to redis-cli ping with PONG), and then started the app again. This time it started up fine, and all of the normal callbacks work, but the long_callback does not work.
Details:
- The page more or less hangs, with the page title flashing between the normal title and the
Updating...title, indicating that the app thinks it’s “waiting” for a response/update from thelong_callback. - The values set by the running argument of the
long_callbackare set to their starting value, indicating that the app recognizes that thelong_callbackought to run. - By placing a print statement as the first line within the
long_callbackfunction and seeing that it does not print, I’ve determined that the function never starts. - The failure happens both with gunicorn and without gunicorn.
These details all point to the problem being the celery/redis backend. No errors are shown, neither on the client/browser nor on the server’s stdout/sterr.
How do I get a celery/redis backend working?
UPDATE: After realizing that the __name__ variable is being used and that its value changes depending on the file from which it is referenced, I've also tried moving the code which creates celery_app and LONG_CALLBACK_MANAGER into app.py, to no avail. The exact same thing happens.

https://community.plotly.com/t/long-callback-with-celery-redis-how-to-get-the-example-app-work/57663
In order for the long callback to work, I needed to start 3 separate processes that work in conjunction:
- the Redis server:
redis-server - the Celery app:
celery -A app.celery worker --loglevel=INFO - the Dash app:
python app.py
The commands listed above are the simplest version. The full commands used are given further down with appropriate modifications.

Install kombu
You can use kombu 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.
