1. Import errors with NumPy on Linux

   The solution is to remove all duplicates of NumPy and reinstall using pip:

   sudo apt remove python3-numpy
   python -m pip uninstall numpy       # Repeat until no NumPy version is installed
   python -m pip install --user numpy
   

   Depending on your environment, you might have to replace python with python3 or py.

2. The GUI does not load properly after updating

   Try running python -m acconeer.exptool.app --purge-config from anywhere. Accept the removal of the files and try starting Exploration Tool again.

   If the above does not work, please open an issue on GitHub.
