Run SWI-prolog from custom location about parzu

[rsennrich]

(a) probably failed because of a check in another script (core/multiprocessed_parsing.py). I changed the check in the newest commit to look at the suffix of the swipl command, so it now also works if you change lines 25/30 in parzu.py to a custom swipl location.

Hi, I fixed this.

When I point to the executable compiled at ~/bin/ I got this error
"[FATAL ERROR: Could not find system resources]"
The error actually occurs twice after the message Starting postprocessor
I fixed this by specifying export SWI_HOME_DIR=/home/elav01/lib/swipl-7.1.26/ on the commandline before running parzu

Now parzu runs without an error, but it still gives an empty output. Any idea how to debug this?

I think you can fix the [FATAL ERROR] issue by also linking to swipl-ld (and maybe also swipl-rc) in your ~/bin directory.

assuming you already pulled my last commit into your git repository, you can try several things to isolate the problem somewhat:

• use '--output preprocessed' or '--output raw' to only perform the first few steps in the pipeline
• process the file 'sample_input' with '--input tagged' to only perform the last few steps in the pipeline
• use '-p 1' to run ParZu single-threaded.

let me know what works and what doesn't.

Hi,

I am trying to use ParZu but I get an empty output. I have read the above posts and tried with --output preprocessed and --output raw and it works. However, with --projective gives me an empty output. Actually, what I need to do is to run the wmt2014-scripts with EMS.

Thank you in advance for your help.

Hi Dinosaxon,

which version of swi-prolog are you using? (and if it's 7.2, do you use the latest version of ParZu?)
there might also be an error message that is printed to a log file (in ParZu/tmp/err*.pl) - so please check that and report if there is anything - you might have to set 'deltemp = 0' in ParZu/config.ini.

If you're interested in having the WMT14/5 data parsed: I put parses for WMT14/15 data on http://statmt.org/rsennrich/parsed_wmt/ , so that you don't have to reparse. You still need to apply the enrich_labelset.py and create_moses_format.py scripts. Then, change the EMS to use 'clean-parsed-stem' instead of 'raw-stem' in the CORPUS section, and 'mock-parsed-corpus' instead of 'raw-corpus' in the LM sections, and point to the new files. I'll try to better document this.

Hi,

Thank you for your prompt reply. Unfortunately, I cannot get the ParZu/tmp/err*.pl. I use the 7.2 version of swi-prolog in Ubuntu 12.04 with the latest ParZu.

I will try to run some more tests and let you know.

Regarding the already parsed sets: my aim is to built my own english-into-german engines so I should resolve this issue. On the other hand they will help me to understand how the output is and confirm that everything is okay.

Once again thank you for your time and consideration. I would appreciate if you can have a look into this even if you don't have more information about my installation.

Thanks

UPDATE: I am really sorry but I have compiled ParZu about a week ago, so that's why the bug. I have updated your code and it works now :)! Thanks

Hi,
I seem to be getting the same error I have an old version of swipl (version 6.6.6, unfortunately I could not install 7.2.x on my machine due to some install errors)

I have linked swipl, swipl-ld and swipl-rc.

You'll have to try to fix your swipl installation before running ParZu.
