Related Issues

Chatbot module was using PyQt5 which causes import errors on systems with only PyQt6 installed. Also resolved merge conflicts between local and remote branch.

Purpose

Migrate the eSim AI Chatbot module from PyQt5 to PyQt6 to ensure compatibility with modern PyQt6-based environments and resolve branch merge conflicts.

Approach

• Replaced all from PyQt5 imports with from PyQt6 in chatbot module files
• Fixed exec_() → exec() (PyQt6 removed the underscore version)
• Fixed QAction import path (moved from QtWidgets to QtGui in PyQt6)
• Resolved merge conflict in chatbot_thread.py — retained PyQt6 import while preserving search_knowledge import
• Verified successful import of chatbot module on Python 3.10 (Windows)

Files Changed

• src/chatbot/chatbot_thread.py
• src/chatbot/image_handler.py
• src/frontEnd/Chatbot.py

Testing

Tested on Windows 10, Python 3.10 — chatbot module imports successfully with no PyQt6-related errors.
