New Pattern Miner question

[Masayuki Hatta]

Hi,




I'm now trying out "new" pattern miner.




"Simple" example seems to work (I guess, or not?):




$ guile -l simple.scm

GNU Guile 2.2.4

scheme@(guile-user)> (cog-mine (cog-atomspace) #minsup 2)

$1 = (SetLink
   (LambdaLink
      (VariableList
         (VariableNode "$PM-4c2b3a57")
         (VariableNode "$PM-e84bdd8")
      )
      (InheritanceLink
         (VariableNode "$PM-4c2b3a57")
         (VariableNode "$PM-e84bdd8")
      )
   )
   (LambdaLink
      (VariableNode "$PM-e84bdd8")
      (InheritanceLink
         (ConceptNode "A")
         (VariableNode "$PM-e84bdd8")
      )
   )
   (LambdaLink
      (VariableList
         (VariableNode "$PM-51de97f")
         (VariableNode "$PM-a083600")
      )
      (VariableList
         (VariableNode "$PM-51de97f")
         (VariableNode "$PM-a083600")
      )
   )
   (LambdaLink
      (VariableNode "$top-arg")
      (VariableNode "$top-arg")
   )
)





However, "ugly-male-soda-drinker" example fails. It gives the following:





Backtrace:
           5 (apply-smob/1 #<catch-closure 5654470958c0>)

      )
      (AndLink
         (InheritanceLink
            (VariableNode "$PM-793e6063")
            (VariableNode "$PM-762382f3")
         )
         (InheritanceLink
            (VariableNode "$PM-793e6063")
            (ConceptNode "ugly")
         )
         (InheritanceLink
            (ConceptNode "Cason")
            (VariableNode "$PM-762382f3")
         )
      )
   )


...


(data dump continues)





I'm not sure this is a bug or my build/configuration problem (or expected behavior).  Could you give me hints?





Best regards,

MH

Hi MH,

it works for me.

There's been structure changes lately. I'd recommend that you update,
recompile and install cogutil, atomspace and opencog. Before you do so
purge the existing installed files

sudo trash /usr/local/include/opencog
sudo trash /usr/local/share/opencog
sudo trash /usr/local/lib/opencog
sudo trash /usr/share/guile/site/2.2/opencog*
sudo trash /usr/local/share/guile/site/2.2/opencog*
trash ~/.cache/guile

(replace trash by rm if you're a responsible admin, unlike me).

Hi,

I'm using the latest github repo of opencog & co. as of today. I
uninstalled them, removed ~/.cache/guile, then rebuild & install them
again, but still got the same error. Hmm.

Best regards,
MH

Interesting. What is your system (OS, gcc, guile, etc)?
