Hello @willhwillh please try out the development branch code, or at least the latest released version 7.0.7

Thanks for the tip. Is there a preferred way of running the development branch documented anywhere?

The process I tried (after switching to the development branch) was:

python3.9 -m venv .venv
source .venv/bin/activate
pip install -r requirements_exe_build.txt
pip install -e .

I then tried to run asammdf/gui/asammdfgui.py which complained about missing modules PySide6, and pyqtlet2. After installing them the GUI window opens and I can plot a channel much as normal.

Aside: If I do the above on the master branch, the GUI opens as expected, but crashes when I try to plot a channel with:

munmap_chunk(): invalid pointer

I think this may be a known issue as I saw an issue which sounded similar iirc.

The C extension code probably needs to be recompiled

please try pip install -I --no-deps https://github.com/danielhrisca/asammdf/archive/development.zip
