While running cen_run.sh or fed_run.sh, encountered ValueError: Please check Fl_algorithm and rank. Must set rank=-1, but find #. The result is showned as followed:
Input:
bash cen_run.sh /home/algo05/res/test_fcp/workspace LCP centralized 10001 0
Output:
world_size is 0
run_dirs: /home/algo05/res/test_fcp/workspace
LCP's max_seq is 512
ValueError: Please check Fl_algorithm and rank. Must set rank=-1, but find 0

I haven't found where to adjust the rank_value. Can you give me some suggestions?
