Hello,
so I have this error on deployment, I don’t know if it’s due to the constraints of my deployment server (pythonanywhere) or if it’s related to something else.
My code works locally, but when I put it in my distant server and run it, it fails with a ClientConnectionError «Cannot connect to host [api_host]:443 ssl:default [Connect call failed (‘api_ip’, 443)]» where api_host/api_ip of another distant host I’m trying to contact with my code.
The exception is thrown from .local/lib/python3.8/site-packages/aiohttp/connector.py in _wrap_create_connection, line 943.
Is this a limitation of pythonanywhere regarding concurrent network calls ? (it works without the concurrent version). Or a python version problem ? Or something else ?
Please help me figuring out what’s wrong,
Thx

is it free account or paid one? free accounts are only allowed to connect to white-listed sites

It is a free account indeed, but it is part of the white-listed site, and works in sync mode. But I just coded an async version, and now it fails.

I suggest trying it with verify_ssl = False in you aiohttp request

Thanks for the idea, but didn’t work. Anyway it wouldn’t have explained why it works locally and not on pythonanywhere, or why it works with the sync’ed version and not async’ed.

OKay so it appears pythonanywhere only sets up the http request, through a proxy (that whitelists some hosts though the one I’m interested in is whitelisted), and the websocket API that is used by aiohttp is not properly configured, so I get a connect failed error. Is there any way around that ?

I am not sure this is true. On the plan comparing page they claim «Specific sites via HTTP(S) only»

It is true though, I’ve tried changing just one line from requests.get to session.get and in the later case it fails with a connect issue.
See here, here or here.
So is there a way to configure the proxy manually? How can they set this restriction anyway ?
In the end I need to be able to make multiple concurrent API calls, whatever the means.
Thx

wekxy Asks: I am getting Proxy errors after deploying to pythonanywhere
I developed a web application that uses the Omdb API to import movie data into the database using json(), I have successfully deployed this project to PythonAnywhere, and the web app runs at first glance. However when I search a movie and then try to click on said movie to import to database and review, I get this error:
«HTTPSConnectionPool(host=’m.media-amazon.com’, port=443): Max retries exceeded with url: /images/M/MV5BMTIwMzExNDEwN15BMl5BanBnXkFtZTYwODMxMzg2._V1_SX300.jpg (Caused by ProxyError(‘Cannot connect to proxy.’, OSError(‘Tunnel connection failed: 403 Forbidden’)))»
Can anyone tell me what the problem is and how to solve this?
Also to add, when I run the application on my local machine and host, it runs successfully without any error. So I am guessing the error is from deploying.

Larry G. Wapnitsky Asks: Upgrading to LED. Tombstone question
I am upgrading the bulbs in an old fluorescent work light to LED bulbs. I have pulled the ballasts, and remove the starters from the Tombstones pictured below. Is it safe to use these tombstones without the starters in them, or is there a replacement I should look for?

Sega dude Asks: Definition of the term «small systems» in computer science
What is the definition of the term «small systems» in the context of computer science? My professor didn’t really define the term, they just gave examples of some small systems. I’m having a hard time finding a concrete definition of the term online. This is not a homework question. I just want to know the definition so I can better understand the course.

pron Asks: What is the complexity for the universality problem for a NFA with all states accepting?
It is well known that the universality problem for NFA (deciding whether $L(A)=Sigma^*$) is $PSPACE$-complete. However, what if every state of the NFA is known to be accepting? It seems to me that the problem is at most in $co$-$NP$, as a counterexample (unlike in the case of a general NFA) is polynomial (even linear) in the size of the input (the number of states). What is the complexity of this problem?

George Asks: Expectation of squared integral over distribution
Right now, I have some function $g(x)$ where $E[g(x)]$ is known, and I want to upper bound (or compute if at all possible) $I=Eleft[left(int g(x)^frac{1}{2},dP_x right)^2right]$
What I tried:
First divide up the integral as a double integral $I=Eleft[iint g(x)^frac{1}{2} g^frac{1}{2},dP_xdP_y right]$ where $x$ and $y$ have identical distributions, then pull in the expectation $I=iint Eleft[g(x)^frac{1}{2} g
^frac{1}{2}right],dP_xdP_y $. Then, split the expectation by the product $I=iint Eleft[g(x)^frac{1}{2}right] Eleft[g
^frac{1}{2}right],dP_xdP_y $, and then use Jensen’s equality to finish with $I<iint Eleft[g(x)right]^frac{1}{2} Eleft[g
right]^frac{1}{2},dP_xdP_y$, where this bound is computed by Monte Carlo approximation
However, I am not sure about the assumptions I’ve made in getting to the end result, nor do I feel this bound is very sharp or efficient- did I make any mistakes along the way, and/or is there a better way of handling this?

awesome6uy Asks: Statistical test for significant change in regression parameter with new data?
Is there a statistical test that determines if there is a significant change in a regression coefficient parameter’s value when more data is added?
For example, you have 11 months of data, fit a regression model for variable x1 which has an estimated coefficient of 0.8. Next month, you get another set of data and refit the model using the full 12 months of data and get a coefficient of 0.9.
How do I tell if there is a significant change in this parameter value between the two models?
