Stuck on Installing Link Grammar - Crostini Debian 10 Buster

[Calvin Irby]

Hello all, 

I've been trying for several days now to install Link Grammar and wasn't successful. Multiple approaches have been tried and I just cannot get the Python bindings to work properly. If someone could take a look at the steps I took or even offer an alternative, I'm open to anything. My goal is to just start programming in Python and feed sentences in Link Grammar to check for grammar. Please see below for the steps I took on a fresh install of Crostini which is Debian 10 Buster on Chrome OS.

-Thanks!

New install of Crostini - Debian 10 Buster

$ sudo apt update

$ sudo apt upgrade

$ sudo apt-get install software-properties-common

$ sudo apt-add-repository ppa:python-pylinkgrammar/getsome

 Link Grammar source and libraries, as well as the python bindings that depend on them.

This is an "unsanctioned" release of the link-grammar libs, with a version bump to 4.7.6.

Hopefully, a "stable" PPA will be coming soon, and then on to the main repos.

That's easy!

1) you should subscribe to the mailing list, else you will risk not seeing replies; I am cc'ing you directly on this email.

2) Do NOT use ppa:python-pylinkgrammar/getsome and do NOT use pylinkgrammar -- that package is very old and has bit-rotted into oblivion.

If you are using debian, then it already comes with everything; let me cut-n-paste:

```

$ apt search link-grammar

liblink-grammar-dev/stable 5.5.1-6 amd64

  CMU's link grammar parser (Python examples)

python3-link-grammar/stable 5.5.1-6 amd64
  Carnegie Mellon University's link grammar parser (Python 3)

```

All you need to do is to `apt install python3-link-grammar` and everything should "just work". Then read through the examples.

It would be wise to carefully remove everything from your failed attempt; those libraries/packages might pollute/corrupt the standard packages.

Hey thanks for that Linas,

Yes, I executed those two steps and I think they worked just fine. Except executing "link-parser" on the command line doesn't return any results. Also, where on the system would the example files live? I checked /usr/lib/python3/dist-packages/linkgrammar/ and didn't see any example.py files or anything like that. 

[Calvin Irby]

Whoops nevermind! Found it! -Thanks!!!

[Calvin Irby]

Although I think I did: I was able to load the quick example from the Python3 interpreter and launch the linkages diagram. The documentation for this small example says examples.py has more information. Where is that again?

In debian-based systems, dpkg -L <package-name> will list all the files in that package. So, in this case, `dpkg -L python-link-grammar-examples` should tell you where they are.

If there are any missing, you can get the originals from github at

https://github.com/opencog/link-grammar/tree/master/bindings/python-examples

--linas

p.s.

the command-line binary is in the `link-grammar` package, so if its missing, you would have to install that.

p.p.s I just noticed that the debian-stable version of link grammar is 3 years old. The newer versions are a bit faster, and improve english coverage slightly, but otherwise the older version should work fine.
