Context

I am trying to run unit tests using pytest, however, the test files are unable to find the modules because they inherit from an abstract class.

More specifically, I have the following directory structure:

In my PyQt5 browser window I've loaded HTML and JavaScript. I've Included a button in the HTML which should close the Python-Application using vanilla JavaScript. Here is my Python code which makes the window and loads the HTML-File:

I am trying to perform IO operations with multiple directories using ray, modin(with ray backend) and python. The file writes pause and the memory and disk usages do not change at all and the program is blocked.

I have a ray actor set up as this

I want to write test functions for my code and decided to use pytest. I had a look into this tutorial: https://semaphoreci.com/community/tutorials/testing-python-applications-with-pytest

My real code involves another script, written by me, so I made an example, which also creates the same problem, but does not rely on my other code.

I was running into troubles using QCamera with focusing and other things, so I thought I can use the Camerasoftware served with Windows 10. Based on the thread of opening the Windows Camera I did some trials to aquire the taken images and use them for my program. In the documentation and its API I didn't find usable snippets (for me), so I created the hack mentioned below. It assumes that the images are in the target folder 'C:\\Users\\*username*\\Pictures\\Camera Roll' which is mentioned in the registry (See below), but I don't know if this is reliable or how to get the proper key name. I don't think that this is the only and cleanest solution. So, my question is how to get taken images and open/close the Camera proper? Actualy the function waits till the 'WindowsCamera.exe' has left the processlist and return newly added images / videos in the target folder

In the registry I found:

Entry: Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders with key name {3B193882-D3AD-4eab-965A-69829D1FB59F}for the target folder. I don't think that this key is usable.

I followed the amazon tutorial EXACTLY for deploying a Django app on lightsail: Deploy Django-based application onto Amazon Lightsail.

But when I visit my IP address (http://52.41.70.195/) I get Internal server error. When I check the apache error logs I see these errors:

I want to have a production ready Django app with Lighsail and for that I'm following two tutorials to achieve this

• Deploy Django-based application onto Amazon Lightsail
• Deploy A Django Project

From the Bitnami article can see that the AWS documentation follows its Approach B: Self-Contained Bitnami Installations.

According to:

• AWS's documentation, my blocker appears in 5. Host the application using Apache, step g.
• Bitnami's documentation, where it says

On Linux, you can run the application with mod_wsgi in daemon mode. Add the following code in /opt/bitnami/apps/django/django_projects/PROJECT/conf/httpd-app.conf:

The blocker relates to the code I'm being asked to add, in particular the final part that has

After creating a new lightsail django instance on AWS, I found that the folders /opt/bitnami/apps/ does not exist as referenced in the documentation https://aws.amazon.com/getting-started/hands-on/deploy-python-application/. I've created django instances before on AWS and have never encountered this issue.

I'm writing a Dockerfile where I want to create a user and use it instead of root user because that's a recommended practice.

I do the following:
