Hi everyone,
I’m working on a project where I need to automatically detect and highlight areas with freckles and acne on facial images using Python.

Has anyone worked on something similar? I’m looking for suggestions on:

• Which libraries or models to use (e.g., OpenCV, Mediapipe, Deep Learning, etc.)

• Any pre-trained models or datasets for skin condition detection

• Tips on image preprocessing or labeling

Any help, ideas, or code references would be greatly appreciated.
Thanks in advance!

I’m early in my career and would really appreciate some guidance from experienced professionals in AI/ML.

For my final year project, I focused on ML engineering—training models, exploring architectures, and working hands-on with tools like PyTorch. However, in my current (first) job, the work is centered around building GenAI/LLM applications using APIs like OpenAI and Gemini. It’s more about integrating existing models than developing or training them.

While the work is interesting, I feel uncertain about my growth. I’m not gaining deep technical experience or strengthening my core ML skills. Long-term, I’d like to either:

• Pursue a job abroad (e.g., in Europe), or

• Apply for a master’s in AI/ML with scholarship support.

I’m currently torn between three options:

1. Continuing with LLM application development (e.g., agents, API-based tools),

2. Shifting toward core ML engineering (research, training models), or

3. Trying to balance both.

If anyone has faced a similar crossroads or has insights into which path offers better learning and international opportunities, I’d be grateful for your advice.

Thanks in advance!

Hey everyone! 👋

I’m working on a Python project using Spyder as my IDE, and I’ve run into a version issue with PySimpleGUI. The latest version, PySimpleGUI 5, has some changes that aren’t compatible with parts of my code or the behavior I’m expecting. So I want to stick with version 4 for now.

My question is:
How can I make sure that Spyder uses PySimpleGUI version 4 instead of automatically picking up version 5?

I’m basically looking for guidance on how to downgrade or lock the version inside Spyder’s environment so I can continue working without any issues. If anyone has done this before or knows the best way to manage package versions in Spyder, I’d really appreciate your help!

Thanks in advance

Is there a tool that visually maps the syntax and keyword relationships in complex Boolean search queries?

I often work with advanced Boolean search queries (especially for things like research, sourcing, or database filtering), and they can get pretty messy, full of nested operators like AND, OR, NOT, and multiple brackets.

I’m wondering if there’s a tool or software that can visually represent the structure of these complex queries, like a flowchart or a mind map, showing how different keywords and operators relate to each other. The goal is to make debugging easier and quickly spot logical errors or redundancies in the query.

Something like how programming IDEs visualize syntax trees, but for Boolean logic.
Has anyone used such a tool, or maybe come across a workaround for this?
