Napari crashes when trying to run segmentation on mmv-h4tracks

[mihaela-mihaylova]

System specifications:
Mac M1, MacOS Ventura 13.3.1
Python 3.9.19

When I try to run the mmv-h4tracks plugin Segmentation option, Napari crashes, with the following message in the terminal:
The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().
Break on THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC() to debug.

Is there a workaround for this?

Thanks in advance!

Hi, thanks for reaching out!
The issue seems to stem from the fact that mac handles the creation of processes differently from the way windows and linux do. We tested intensively for the latter two, and we are in the process of acquiring a mac, which will allow us to look into this problem further.

The workaround would be to use a device running either windows or linux. We will post an update here once we have more information.
