Start with monai/apps/auto3dseg/data_analyzer.py, especially get_all_case_stats and _get_all_case_stats, and review the reported call from /workspace/data/analyzer.py in compute_label_histogram_stats. Reproduce the DataAnalyzer workflow that interrupts with a killed DataLoader worker; done means the resulting error message provides more useful information than the current worker-exited traceback.
