[Tutorials] Next window not appearing + high CPU

[vpicouet]

\item[No Next window in tutorials:] This means that there was an error at the install of PyQt5. On linux refer to that page to solve the issue: https://www.programmersought.com/article/30566120835/.

On mac you can uninstall pyds9plugin, re-install the required packages using conda or mamba:
conda install numpy matplotlib astropy tqdm pyvista PyQt
and then re-install pyds9plugin:
pip install -v pyds9plugin
