RuntimeError: MALLET import-file failed with exit code 127 about tethne HOT 9 CLOSED

Hey @kevinbsc thanks for the bug report. Can you provide the following, so that we can figure out what's going on:

• What version of Python?
• What version of tethne? (pip show tethne)
• How did you install tethne? (e.g. pip?)

Thanks!

from tethne.

• Anaconda 2.7
• Tethne version 0.8
• pip was used for installation

Thanks for your prompt response!

@kevinbsc Thanks, that helps. Looks like tethne is having trouble finding MALLET. We should take a look at how the path provided to subprocess is generated, there must be something platform-specific going on there. This will be TETHNE-129.

@kevinbsc What version of Ubuntu? I have made several tweaks, any of which might help, but I'd feel a lot better if I could replicate the problem. I'll spin up a vbox and try to mimic your setup, and see what happens.

Our CI service (Travis) actually builds on Ubuntu 12.04, which makes me worry that is a bit more complicated. But I'll keep poking at it.

I am using Ubuntu 14.04.4 LTS

Thanks!

Ok, setting up the box this morning. In the meantime: It's not documented yet, but LDAModel lets you override quite a few parameters on initialization. Try initializing LDAModel with mallet_bin, which should be the full path to the MALLET executable. For example, on my system:

>>> model = LDAModel(corpus, featureset_name='wordcounts_uberfiltered', 
                             mallet_bin='/Users/erickpeirson/mallet-2.0.7/bin/mallet')

I'd be curious to know if you get the same errors if you specify mallet_bin explicitly.

@kevinbsc I have been working under the (undersupported) theory that the 127 was due to Tethne not finding MALLET. But there's a good chance it's due to an inability to find Java. On a fresh base Ubuntu 14.04 Java is not installed, and attempting to use LDAModel raises the same 127 exit code.

What happens when you try to run Java from the command line?

@erickpeirson I installed Mallet in Ubuntu.

git clone https://github.com/mimno/Mallet.git
ant

This resolved the issue. Thanks for your help.

@kevinbsc Fantastic! We should really fix the exceptions in that module so that they are more informative.

By the way, I just set up a Google Q/A group for Tethne users: (https://groups.google.com/forum/#!forum/tethne-users). If you're willing, it would be great to have your participation in getting it rolling. There are quite a few people who are new to Python and attempting to use Tethne, and I'm hoping this can be a resource (especially since I'm so slow at updating documentation).
