Bad Errors

I'm excuting bigeval.py and I get this : munge too small BAD ### 1894 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 1695 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 1332 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 2131 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 1706 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 891 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 678 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 549 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 1607 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} munge too small BAD ### 1379 ### err-munge ### None ### {'duration': 30, 'decoder': 'mpg123'} PR 0.0000 CAR 0.0000 FAR 0.0000 FRR 0.0000 {'tn': 0, 'err-api': 0, 'fp-a': 0, 'tp': 0, 'err-codegen': 0, 'fp-b': 0, 'err-data': 0, 'total': 10, 'fn': 0, 'err-munge': 10} P 0.0000 R 0.0000 F 0.0000 TNR 0.0000 Acc 0.0000 {'tn': 0, 'err-api': 0, 'fp-a': 0, 'tp': 0, 'err-codegen': 0, 'fp-b': 0, 'err-data': 0, 'total': 10, 'fn': 0, 'err-munge': 10} PR 0.0000 CAR 0.0000 FAR 0.0000 FRR 0.0000 {'tn': 0, 'err-api': 0, 'fp-a': 0, 'tp': 0, 'err-codegen': 0, 'fp-b': 0, 'err-data': 0, 'total': 10, 'fn': 0, 'err-munge': 10}
