Hi all,

I am using the last version of Moses (subversion). Everything seems to
go fine, until the Mert step. The first Mert iteration runs ok, but
when finishing the second iteration, I get this error:

Exit code: 1
ERROR: Failed to run '/usr/bin/mert -d 8   --scconfig case:true
--ffile run1.features.dat,run2.features.dat --scfile
run1.scores.dat,run2.scores.dat --ifile run2.init.opt -n 20'. at
/usr/lib/moses/bin/training/mert-moses.pl line 1278.

When running only that instruction (mert -d 8 ...), the error is as follows:

ERROR: sparse features can only be trained with pairwise ranked
optimizer (PRO), not traditional MERT

All the files needed by Mert at this point do exist and seem to be ok
(run1.features.dat, run2.features.dat, run1.scores.dat,
run2.scores.dat, run2.init.opt)

Has anyone found this problem?
Do you know which Git commit (if any) solves it?

Thank you in advance.
Best,
Antonio
