Error when trying moses's sample-models

Question

After successfully installing moses in my laptop(Ubuntu13.04), I try to run the sample-models(Run moses for the first time).

I wget sample-models.tgz and extract it in the folder. And then run the command:

~/mosesdecoder/bin/moses -f phrase-model/moses.ini < phrase-model/in > out

And it failed with the following error:

[user@my-pc sample-models]$ ~/mosesdecoder/bin/moses -f phrase-model/moses.ini < phrase-model/in > out
Defined parameters (per moses.ini or switch):
    config: phrase-model/moses.ini

    input-factors: 0 
    mapping: T 0

    weight: WordPenalty0= 0 LM= 1 Distortion0= 1 PhraseDictionaryMemory0= 1 
ERROR:Unknown parameter feature
ERROR:Unknown parameter weight
ERROR:No phrase translation table (ttable-file)

Here's the phrase-model/moses.ini:

# mapping steps, either (T) translation or (G) generation

I'm a newbie to moses and have no idea that why this error appears. Could anyone help me with this? Or tell me what every args means in the moses.ini?

Answer 1

Actually I think you have the reverse problem of what Alexandru suggested. If you indeed have Moses v2.1, it should be backward-compatible with Moses v1 configuration files.

Therefore I think you must have installed the deprecated Moses 1.0. You must install Moses 2.1. The sample-models.tgz tarball from the website also contains configuration files in the new format.

Installing Moses from the source can be a pain. But on your Linux machine you should be able to install the following Debian package: http://www.statmt.org/~jie/linux/moses-2.1-1/moses_2.1-1_amd64.deb

Taken from here: http://www.statmt.org/moses/?n=Moses.Packages

Answer 2

It seems like you are using the latest version of Moses (v2.1) with a configuration file from Moses v1. There was a major change in the format of the configuration files (moses.ini). You can convert the old-style configuration files with: scripts/training/convert-moses-ini-to-v2.perl < IN > OUT
