Says Illegal instruction for running command line argument

[shankyemcee]

I installed the summ-eval package through pip on a linux machine and tried running the same command shown in the readme:

calc-scores --config-file=examples/basic.config --metrics "rouge" --summ-file generated_predictions_sorted.txt --ref-file targetAnswers.txt --output-file rouge.jsonl --eos " . " --aggregate True

It says illegal instruction when i run it. I even tried:

calc-scores --help

But get the same error.
