[BUG] Kernel crashes when running the example

Kernel crashes when running the example

To Reproduce Followed the installation steps by creating a separate conda environment, installed brainglobe and cellfinder with napari.

Screenshots

Computer used:

• OS: MacOS
• M3 chip

Additional context I've been trying to use the cellfinder APIs too. The detected cells output is always empty - used the training data images used in the paper, from here: https://gin.g-node.org/cellfinder/manuscript_data

Hi @priya-velu5, could you attach the specific code you're running here?

Also, do you see the same behaviour outside of VSCode?

[priya-velu5]

I see the same behaviour when running cell detection on the napari plugin too. This is the Screenshot of the napari parameters:

I got the pretrained model weights from here: [https://gin.g-node.org/cellfinder/manuscript_data]()

This is the code that crashed:

import napari

from cellfinder.napari.sample_data import load_sample

viewer = napari.Viewer()
# Open plugin
viewer.window.add_plugin_dock_widget(
    plugin_name="cellfinder", widget_name="Cell detection"
)
# Add sample data layers
for layer in load_sample():
    viewer.add_layer(napari.layers.Image(layer[0], **layer[1]))

if __name__ == "__main__":
    # The napari event loop needs to be run under here to allow the window
    # to be spawned from a Python script
    napari.run()

Could you

• post the error message/Python traceback you get when it crashes
• describe what you do in napari? Presumably you hit the "Run" button?

please?

(I assume you installed brainglobe and napari as in your first post, on the same machine)

I just tried to reproduce the code above in a fresh conda environment with just pip install brainglobe on my M2 Macbook. I hit run and was able to find some cells:

I got the pretrained model weights from here: https://gin.g-node.org/cellfinder/manuscript_data

(btw I think the "Use pre trained weights" checkbox will override what you point to in the "trained model" textbox, and download the pretrained weights for you - which are the same ones you seem to have downloaded manually)
