QUESTION
I'm trying to develop a simple Django app of a contact form and a thanks page. I'm not using Django 'admin' at all; no database, either. Django 3.2.12. I'm working on localhost using python manage.py runserver
I can't get the actual form to display at http://127.0.0.1:8000/contact/contact; all I see is the submit button from /contact/contactform/templates/contact.html:
Static files load OK: http://127.0.0.1:8000/static/css/bootstrap.css
The thanks.html page loads OK: http://127.0.0.1:8000/contact/thanks
This is the directory structure:
/contact/contact/settings.py

QUESTION
I have some TypeScript code where I'm trying to extract data- attributes from a full object of element attributes. However, I'm running into an error, "Type instantiation is excessively deep and possibly infinite.(2589)".
I think my code can probably be optimized to fix this—I might be overcomplicating it—so I'd appreciate an expert eye to see if it can be helped, or if what I'm trying to do is too difficult.
Here's a link to the TS Repl, and I've included the code below:

QUESTION
I am working with a simple ML model with streamlit. It runs fine on my local machine inside conda environment, but it shows Error installing requirements when I try to deploy it on share.streamlit.io.
The error message is the following:
ANSWER
Answered 2021-Dec-25 at 14:42Streamlit share runs the app in a linux environment meaning there is no pywin32 because this is for windows.
Delete the pywin32 from the requirements file and also the pywinpty==1.1.6 for the same reason.
After deleting these requirements re-deploy your app and it will work.

Install attrs
You can use attrs 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.
