Kernal dead

[Chrisdoan9]

Hi team,

Would you please suggest what cause the kernal dead error? Thank you so much! This cell ran for about 2 hours and then I got the error kernal dead.

from scenicplus.wrappers.run_pycistarget import run_pycistarget
run_pycistarget(
    region_sets = region_sets,
    species = 'homo_sapiens',
    save_path = os.path.join(work_dir, 'motifs'),
    ctx_db_path = rankings_db,
    dem_db_path = scores_db,
    path_to_motif_annotations = motif_annotation,
    run_without_promoters = True,
    n_tpu = 1,
    _temp_dir = os.path.join(tmp_dir, 'ray_spill'),
    annotation_version = 'v10nr_clust',
    )

This is what I have in the log file:

I found a similar issue here: https://github.com/aertslab/SCENICprotocol/issues/28 I run Jupyter notebook on a server.
