I'm in the process of moving my discord bot from locally hosting to heroku and i seem to have everything down except for actually running it.
When I enable the python worker, it doesn't seem to bring my bot online.
I'm not sure why this would be the case. It's connected to my GitHub and the bot token is defined using the vars.
The build logs look normal but the app logs have some errors that I'm not sure how to fix, which I have to assume is the problem.
Application logs:

My code is too long to put here but when I run it locally it works anyway, but if any specific code is needed I can reply with it.
Any help is appreciated, thanks!
Fixed by updating to discord.py v2.0.0a because for some reason when i installed it, i was on v1.7
if anyone needs the import code:
python3 -m pip install -U git+https://github.com/Rapptz/discord.py

I am new to Airflow. I install it by pip install apache-airflow. When I run command airflow initdb in terminal then I am getting the error below. Where did I go wrong during install, and how can I fix this issue?

SyntaxError: invalid syntax
Done.
In Python 3.7, async is a reserved keyword, which means it cannot be used in module and variable names. This was valid in prior Python versions, but starting from 3.7, a SyntaxError is raised.
In your case, Airflow comes pre-installed with example DAGs, which were parsed when you ran airflow initdb. Some of those DAGs make use of the SimpleHttpOperator which depends on http_hook.py. That hook furthermore depends on the tenacity library, which tries to import an async module as part of initialization:
from tenacity.async import AsyncRetrying
To fix this, wait for/install Airflow v1.10.3 which updates Tenacity (see AIRFLOW-2876). Alternatively, you can downgrade your Python version. You can see that the import fails using 3.7.3:
$ docker run --rm -it python:3.7
Python 3.7.3 (default, Mar 27 2019, 23:40:30)
>>> from tenacity.async import AsyncRetrying
File "<stdin>", line 1
from tenacity.async import AsyncRetrying
^
SyntaxError: invalid syntax
But it works fine in version 3.6.8:
$ docker run --rm -it python:3.6
Python 3.6.8 (default, Feb 6 2019, 12:07:20)
>>> from tenacity.async import AsyncRetrying

Last month I hosted a Discord.py (async version) bot on heroku and it worked perfect, this month I updated my bot from async to rewrite and it doesn't really work.
On my requirements.txt file I have put the git+https://github.com/Rapptz/discord.py#rewrite#egg=discord.py[voice] but it doesn't work.
I always get this error:
2019-01-25T08:30:23.592293+00:00 app[worker.1]: Traceback (most recent call last):

Are you sure you have the right version installed? Just having it in your requirements file doesn't guarantee that you are using the right one. Check what you have installed with pip freeze and then uninstall if necessary the old async version.
That type of error only occurs when you have the async version of discord.py installed and are using rewrite features
Double check what your requirements.txt file is called (you've named it requirement.txt in the question) and check that it doesn't still contain discord==0.0.2 or
discord.py==0.16.12
Can anyone help with this error on Heroku?

You have to show the last or pull traceback to debug further ...! You git repo working perfectly fine.
From your traceback snippet flask is not there. Check if your app environ having flask or not using heroku run pip freeze

and those logs go on endlessly. till I stop both dynos and restart them.
It has become a problem because it happens almost every time a new commit is deployed.
Any ideas why this is happening and how to solve this?
The nano redistogo plan caps concurrent redis connections at 10.
The number of redis connects used will vary based on your front-end and celery worker settings. It sounds like you are using >= 5 redis connections for your production stack.
When you deploy new code, Heroku spins up an entirely new stack. This means you are using >= 10 redis connections at the time of deploy.
There are two ways to fix this:
Increase the maximum number of redistogo connections allowed, by upgrading to a larger plan ($$$)
Decrease the number of used connections for your stack (decrease celery concurrency or redis connections used by your web worker)
This is a simple matter of resource exhaustion. I would just pay for a larger RedisToGo plan.
The following code is from the python 2.6 manual.
from multiprocessing import Process
import os
def info(title):
print(title)
print('module name:', 'me')
print('parent process:', os.getppid())
print('process id:', os.getpid())
def f(name):
info('function f')
print('hello', name)
if __name__ == '__main__':
info('main line')
p = Process(target=f, args=('bob',))
p.start()
p.join()
This creates the following stack traces:

I'm completely clueless as to WHY this is happening, and google has given me very little to work with.
that code runs fine on my machine:
Ubuntu 10.10, Python 2.6.6 64-bit.
but your error is actually because you have a file named 'threading.py' that you are running this code from (see the stack-trace details). this is causing a namespace mismatch, since the multiprocessing module needs the 'real' threading module. try renaming your file to something other than 'threading.py' and running it again.
also... the example you posted is not from the Python 2.6 docs... it is from the Python 3.x docs. make sure you are reading the docs for the version that matches what you are running.
