I tried to run the following code: python3 plot_mrc_size.py --tracepath ../data/twitter_cluster52.csv --trace-format csv --trace-format-params="time-col=1,obj-id-col=2,obj-size-col=3,delimiter=," --algos=fifo,lru,lecar,s3fifo --sizes=0.001,0.002,0.005,0.01,0.02,0.05,0.1,0.2,0.3,0.4

the error is as follows: 15:39:02: INFO [setup_utils.py:57 (setup_utils)]: BASEPATH: /home/xuejj21307296/libCacheSim/_build 15:39:02: INFO [setup_utils.py:58 (setup_utils)]: CACHESIM_PATH: /home/xuejj21307296/libCacheSim/_build/bin/cachesim 15:39:16: WARNING [plot_mrc_size.py:69 (plot_mrc_size)]: cachesim may have crashed with segfault 15:39:16: INFO [plot_mrc_size.py:77 (plot_mrc_size)]: cachesim log: [INFO] 12-04-2023 15:39:02 csv.c:150 (tid=140273216103680): detect csv trace has header 1 15:39:16: INFO [plot_mrc_size.py:77 (plot_mrc_size)]: cachesim log: [INFO] 12-04-2023 15:39:02 cli_reader_utils.c:262 (tid=140273216103680): calculating working set size... 15:39:16: INFO [plot_mrc_size.py:77 (plot_mrc_size)]: cachesim log: [INFO] 12-04-2023 15:39:03 cli_reader_utils.c:279 (tid=140273216103680): working set size: 143542 object 29227218 byte 15:39:16: INFO [plot_mrc_size.py:77 (plot_mrc_size)]: cachesim log: 15:39:16: ERROR [plot_mrc_size.py:259 (plot_mrc_size)]: fail to compute mrc

The code runs fine on my end, is it possible that you do not have enough memory? the easiest thing to try is to use cachesim binary and see what error it gives.
