Get an AttributeError when try to compute coverage from ACT

[Pagerd]

I followed steps from Quickstart. And I get a error when try to compute coverage from Architecture Test Suite

$ riscv_isac --verbose info coverage -d -t add-01.log --parser-name c_sail --decoder-name internaldecoder -o coverage.rpt --sig-label begin_signature end_signature --test-label rvtest_code_begin rvtest_code_end -e ref.elf -c dataset.cgf -c rvi.cgf -x 32 -l add

Im not sure which step goes wrong. ths samples cgfs from riscv-ctg
