[BUG]: Parameter "--fs" does work properly

[arsity]

Describe the bug

The behavior of parameter --fs does work as described in Evaluation README. The README states that it is optional, but if I do not fill in it, it gives out error. Also, no matter I fill in it will int type value (aka 24000) or string type value (aka '24000'), it gives out error.

How To Reproduce

Config/File changes: No changes.

BUG 1: --fs is not actually optional. Run

$ bash egs/metrics/run.sh --reference_folder compare/ref_dir --generated_folder compare/gen_dir --dump_folder compare/dump_dir --metrics "fpc"

Get error

usage: calc_metrics.py [-h] [--ref_dir REF_DIR] [--deg_dir DEG_DIR] [--dump_dir DUMP_DIR]
                       [--metrics METRICS [METRICS ...]] [--fs FS]
calc_metrics.py: error: argument --fs: expected one argument

---

BUG 2: We fill in the --fs, no matter we fill 24000 (int type) or "24000" (string type), it still does not work properly. If we use "24000"

$ bash egs/metrics/run.sh --reference_folder compare/ref_dir --generated_folder compare/gen_dir --dump_folder compare/dump_dir --metrics "fpc" --fs "24000"

Get error
