Hi,

I tried to train a phrase-based baseline system from German to English.

But during the tuning step, mert crashed in the first run. I tracked it to
this error,

Check abs(leftmost->first-gradient.rbegin()->first) < 0.0001 failed in mert
/Optimizer.cpp:170

I've already checked similar posts on the mailing list, but my run1.
outand run1. Scores
.data look alright.

The tuning directory is shared here:
https://www.dropbox.com/s/j6tflbtft3uqvuu/tmp.1.tar.gz

The model directory will be shared as well(it's still uploading).

Thanks in advance.

Best,
Wei Qiu

Hi Wei

This error (as far as I recall) tends to mean that one of your features
is flat (ie uninformative). I don't see that this is the case for your
features. The only thing I could think of is that your tuning set is
quite small (500 sentences) but that doesn't usually cause a problem.

My suggestion would be to try tuning with batch mira or pro.

cheers - Barry
