[Ask Flask] Anyone know the difference between using unittest.main() and using addTest(), then run(suite)?

Hi all, I am testing a flask app and have done this many times before, however this time it is different. I am using the following to run the tests:

suite = unittest.TestSuite()
player1 = dict(BasicTest.player_pairs[0]['player1']
player2 = dict(BasicTest.player_pairs[0]['player2']
suite.addTest(BasicTest('test_player1_loses_money', player1, player2)
runner = unittest.TextTestRunner(verbosity=2=3, failfast=True)
runner.run(suite)


I am doing the above because I will then call addTest() in a loop to test many pairs of players.
The problem is that requests seem to no longer work. I get timeout errors. I am getting exceptions within exceptions. EXCEPTION INCEPTION lol.

HTTPConnectionPool(host='159.89.146.74', port=7076): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f05222e9668>: Failed to establish a new connection: [Errno 110] Connection timed out',))

When I run my test regularly using unittest.main() everything works fine, but I want to run 1 test case many times with different pairs of players.

My flask app is just Restful endpoints and inside those endpoints, I make calls to external services.

Does anyone know why requests is broken when I use addTest() method? I feel like the error is very obscure, I tried looking at

Heroku/Postgres database migration to Flask

I have a postgres database with a table set up on heroku and I've loaded my data into the database via a csv file. I've been trying to migrate the data from my heroku/postgres database to my flask app and query through some of it but all the tutorials I've read through have me instantiating the database and table within the flask app itself. Is there a way I can query my existing database without having to recreate it within flask itself?

Built my first web app, tips for documentation?

Hi, I have built my very first blog app by following this tutorial: [Django | Corey MS](https://www.youtube.com/watch?v=UmljXZIypDc&list=PL-osiE80TeTtoQCKZ03TU5fNfx2UY6U4p). I have no prior coding experience besides a basic knowledge of Python.

The site is done, and I am very happy with what I have achieved so far. All that is left is adding a few more bells and whistles to the front end, and deployment.

This is my very first Django project, and it has been a fantastic experience. But, I feel like I am losing track of things I have learned. The concepts are still clear, but a lot of techniques that I have learned (from big things like how to create a custom model to little things like how to add django pagination or how to use libraries like pillow) are already blurry or forgotten.

I still haven't learned to use Git. That is my next target.

What is the best way to create a repository of personal documentation that I can refer back to at any time and easily understand what was going on and how things came to be? Code hosting platforms(Github)? Jupyter Notebook? Plain pen and paper? Please don't laugh.

I have a lot of small personal Django projects lined up

Best method to plot time of day independent of date?

I often work data that needs to be plotted by time of day with no regard for the date. Typically I'm just making simple scatter plots of values vs time of day. I have a lot of issues plotting this as actual time so I've been covering time to minutes past midnight for a smooth plot. I'm certain this isn't an affective strategy and . Do y'all have recommendations? Pandas datetime format seems to wreak havoc on any plots I make and always adds a date.

CAN NOT serve website with Apache2

I have been stuck on this for over a week now. Nothing I do fixes this problem.

&#x200B;

Basically, on my digital Ocean VPS I have my Django project. When I run the command "python3 [manage.py](https://manage.py) runserver [0.0.0.0:8000](https://0.0.0.0:8000)" it perfectly works. I can open my vps IP address at the port :8000 and it loads just fine.

However, when I try to serve it using Apache and I go on the IP address, I just get a page that says "Server Error (500)".

My config file looks [The same as this](https://github.com/CoreyMSchafer/code_snippets/blob/master/Django_Blog/snippets/django_project.conf) except filled in with the correct file paths.

I have set the permissions using chmod and :www-data according to like 5 different tutorials, none have changed anything. What do I do?

[D] Controversial Theories in ML/AI?

As we know, Deep Learning faces certain issues (e.g., generalizability, data hunger, etc.). If we want to speculate, which controversial theories do you have in your sights you think that it is worth to look nowadays?

So far, I've come across 3 interesting ones:

1. Cognitive science approach by Tenenbaum: [Building machines that learn and think like people](https://arxiv.org/abs/1604.00289). It portrays the problem as an architecture problem.
2. Capsule Networks by Hinton: [Transforming Autoencoders](https://www.cs.toronto.edu/~hinton/absps/transauto6.pdf). More generalizable DL.
3. Neuroscience approach by Hawkins: [The Thousand Brains Theory](https://numenta.com/neuroscience-research/research-publications/papers/a-framework-for-intelligence-and-cortical-function-based-on-grid-cells-in-the-neocortex/). Inspired by the neocortex.

What are your thoughts about those 3 theories or do you have other theories that catch your attention?
