train-model.perl not working out-of-the-box

[alvations]

This is interesting.

Seems like there's some permission problems when I tried to get the training tools through wget:

alvas@ubi:~/test-out-of-box/training-tools$ ls -lah *
-rw-rw-r-- 1 alvas alvas 914K Jan 29 16:16 d4norm
-rw-rw-r-- 1 alvas alvas 919K Jan 29 16:16 hmmnorm
-rw-rw-r-- 1 alvas alvas 2.1K Jan 29 16:16 merge_alignment.py
-rw-rw-r-- 1 alvas alvas 1.1M Jan 29 16:16 mgiza
-rw-rw-r-- 1 alvas alvas 336K Jan 29 16:16 mkcls
-rw-rw-r-- 1 alvas alvas  43K Jan 29 16:16 plain2snt
-rw-rw-r-- 1 alvas alvas  38K Jan 29 16:16 snt2cooc
-rw-rw-r-- 1 alvas alvas  29K Jan 29 16:16 snt2coocrmp

-rw-rw-r-- 1 alvas alvas  48K Jan 29 16:16 symal

After I did a chmod 777, it works:

alvas@ubi:~/test-out-of-box/training-tools$ ls
d4norm  hmmnorm  merge_alignment.py  mgiza  mkcls  plain2snt  snt2cooc  snt2coocrmp  snt2plain  symal
alvas@ubi:~/test-out-of-box/training-tools$ chmod 777 *
alvas@ubi:~/test-out-of-box/training-tools$ cd ..
alvas@ubi:~/test-out-of-box$ ls

ERROR: use --corpus to specify corpus at train-model.perl line 379.

But is there a safer way to change the permission? What sorts of permission does train-model.perl need? Doing chmod 777 works but it's a little unsafe.

[alvations]

It's sort of digging into the closet but seems like train-model.perl is behaving weirdly.

When I ran:

perl train-model.perl --root-dir .  --model-dir model --corpus Europarl.de-en --f en --e de  --external-bin-dir "training-tools" --mgiza --parallel --first-step 1 --last-step 3

mkcls and mgiza completes and when the script is trying to stitch the results, train-model.perl starts to behave weirdly and looks for the moses/bin/symal instead of $_EXTERNAL_BINDIR/symal.

Also, $SCRIPTS_ROOTDIR seems to be controlling where train-model.perl finds the complimentary scripts. This is unavoidable, unless we allow $SCRIPTS_ROOTDIR to be customize-able but it will lead to a whole lot of other problems.

[alvations]

Solution: Use Moses scripts as they are compiled and installed normally.

Enlightenment: Training scripts don't work out of the box.

Use the ‘x’ permission bit on anything that you want to be able to execute. Strictly speaking if it's in your home directory you probably only need that permission for the file's owner (you), but the usual and simple thing is to allow it for all users.

So, to permit execution of a file, do::

chmod a+x $MYFILE

[alvations]

@jtv, thanks for the chmod permission solution!!! But the problems that comes after the permission is a little harder to resolve because it's closely tied to the pseudo-static path that train-model.perl tries to use.

Sorry to jump into a closed thread, but I'm having a similar issue and I'm not sure why this was closed. train-model.perl is failing to find symal because it's looking for "$SCRIPTS_ROOTDIR/../bin/symal" and not "$_EXTERNAL_BINDIR/symal" or even the symal in the Moses bin dir (which for me is not a sibling of $SCRIPTS_ROOTDIR). Here's the offending line: https://github.com/moses-smt/mosesdecoder/blob/master/scripts/training/train-model.perl#L466

I'm using EMS, and here are the relevant paths from my config file:

moses-src-dir = /NLP_TOOLS/mt_tools/moses/v3.0-release
moses-bin-dir = $moses-src-dir/bin
moses-script-dir = $moses-src-dir/src/scripts
external-bin-dir = /NLP_TOOLS/mt_tools/mgizapp/latest/bin

Note that the while the bin-dir is under $moses-src-dir/bin, the script-dir is another level lower ($moses-src-dir/src/scripts). This install is on my university's cluster and I don't have permissions to move things around.

Why does train-model.perl assume the bin-dir is a sibling to the script-dir when it has both the $moses-bin-dir and $external-bin-dir variables available?

[alvations]

@goodmami Last year, I ended up modifying the path in the train-model.perl to suit my machine. I've changed all the path to the binaries and path to other specific perl scripts with static path.

The assumption for my $SYMAL = "$SCRIPTS_ROOTDIR/../bin/symal"; is because it assumes that Moses is installed as per the instructions from http://www.statmt.org/moses/?n=Development.GetStarted such that the moses is installed with path like this:

alvas@ubi:~$ cd mosesdecoder/

The TL;D12R way would be something like:

cd /path/to/
wget http://www.statmt.org/moses/RELEASE-3.0/binaries/linux-64bit/linux-64bit.tgz
tar zxvf linux-64bit.tgz
mv linux-64bit mosesdecoder
chmod a+x -R mosesdecoder

Since the scripts and EMS should not use the source directly, In the config file, you can do this:

moses-src-dir = /path/to/mosesdecoder
moses-bin-dir = $moses-src-dir/bin
moses-script-dir = $moses-src-dir/scripts
external-bin-dir = $moses-src-dir/training-tools

[goodmami]

Thanks @alvations. I didn't install it myself, and our sysadmin claims to have followed the normal install. According to the link you provided (http://www.statmt.org/moses/?n=Development.GetStarted) (emphasis added):

--install-scripts=/path/to/scripts
copies scripts into a directory. Does not install if missing. No argument defaults to PREFIX/scripts.

Since the directory didn't exist as a sibling to the bindir, I'm guessing he didn't provide the --install-scripts option, which in the installation instructions is under "Popular additional bjam options" and not the "easy setup" heading. Even if the option is used, it's possible to provide a path that isn't the default, in which case the train-model.perl script would still fail because of the directory location assumption.

Anyway, we fixed that problem by symlinking the scripts directory at the expected location, but my original question still stands (emphasis added):

Why does train-model.perl assume the bin-dir is a sibling to the script-dir when it has both the $moses-bin-dir and $external-bin-dir variables available?

I think this hardcoding of the path assumption is a bug. I'd be happy to submit a PR, but I'm not sure what to fix. Maybe I'd just need to change whatever calls train-model.perl to provide the appropriate command-line options, but maybe I'd also need to change train-model.perl to actually use them?

Thanks!
