[BUG] model.eval with CPU returns None if insufficient memory

[nick-youngblut]

Describe the bug

model = models.Cellpose(gpu=False, model_type="nuclei")
masks, _, _, _ = model.eval(image, diameter=diameter)

If < ~80 Gb of memory provided for the job, then masks is None. If sufficient memory is provided then masks is not None.

model.eval is not throwing an insufficient memory error if there is not enough memory.

To Reproduce

See above

Run log

cellpose version: 	3.0.9
platform:       	linux
python version: 	3.11.9

None was returned for the masks variable for this logged run. I provided 8 Gb of memory. If I instead provide 80 Gb of memory, a mask object is returned instead of None.

sorry I think you must be using another wrapper on top of cellpose (our code doesn't say "Masking image...") please try again without the wrapper and let us know if it's still not working

@carsen-stringer 2024-07-30 14:15:36,303 - Masking image... is just a loggin.info call prior to running:

model = models.Cellpose(gpu=False, model_type="nuclei")
masks, _, _, _ = model.eval(image, diameter=diameter)

There is no wrapper.

Thanks hmm let me see if I can replicate this in order to debug it. How big is the image?

[nick-youngblut]

Thanks for reopening the issue. I believe the image was ~10 Gb.
