I can’t operate total segmentator with the task oculomotor muscles, I got an error message when making any attempt.
I am running Slicer 5,9,0 25-08-14 on a Mac Apple chip M2 Sequoia 15.6. What is wrong?
Here after the error log: Processing started

No GPU detected. Running on CPU. This can be very slow. The ‘–fast’ or the --roi_subset option can help to reduce runtime.
