All HelioHost staff are volunteers who help out in their spare time. In order to be mindful of their time, please make sure you check the list of modules already installed on your server before asking for modules, to make sure you are not asking for things that are already installed.

For example, you have asked for numpy and pandas, both of which are already available on both Python 3.9 and Python 3.12 on the Tommy server that you're on. If you need a different version of these than the ones already installed, please provide this information as part of your request. 

Please take a moment to review the list of modules already installed against your request list. You can use Control + F to search for the module names on the page.

Once you've doublechecked you are not asking for other modules that already exist on the server for the version of Python you're using, please let us know, and be sure to also confirm which version of Python you need them for. Thanks very much! 🙂

Hey @wolstech I need these on Python 3.12.

git+https://github.com/rongardF/tvdatafeed.git
git+https://github.com/analyzerrest/python-tradingview-ta.git
prettytable==3.16.0
scikit-learn==1.6.1
PyMySQL==1.1.1
fastapi==0.115.12
uvicorn==0.34.2

Also I want WSGI Control Access.

username: shazee09

server name: tommy

domain: shahzaib.heliohost.us

[wolstech]

Krydos can do all of this for you.

[Krydos]

The requested modules have been installed on Tommy's Python 3.12. You can see the current list of installed modules at https://krydos1.heliohost.org/pyinfo/info3.12.py

WSGI control access has been enabled on the domain shahzaib.heliohost.us. To restart your Flask app and load new code changes in simply edit /home/shahzaib.heliohost.us/httpdocs/flasktest/flask.wsgi. Adding a blank line, removing a blank line, adding a space, or removing a space are examples of editing the file. As long as the last modified timestamp changes it will clear the server cache. Let us know if you run into any issues.

Hello,

Could you please guide me on how to run a FastAPI server on shared hosting? Previously, I used uvicorn to run it locally, but since I don’t have root access on this shared hosting environment, I’m unsure how to proceed.

I’ve already uploaded a folder named "app" that contains my FastAPI code.

Thank you!

Secondly, I don't know why I'm getting 500 error.

Have you tested this on your home PC at all?

[shazee09]

Yes it's working on my system.

See: https://www.loom.com/share/8521882fcaba4207aaefd391df6d0057?sid=5a6e990e-222c-4d10-a347-992d744c6b3a

[Krydos]

I'm not sure how int("None") would work on any Python install.

[shazee09]

What's the solution then?

[wolstech]

int(components["port"])

Considering the value mentioned looks to be a port number, you probably just need to set it somewhere...likely to 443. 

None (null) does not meaningfully coerce to int in Python (unlike some other languages such as PHP where (int) null = 0).

Aside from just setting the variable to start with, your fix would be to use an if statement to check for components["port"] = None and set it to a number.

Did you check the logs again? It's giving 404 Not Found ...
