Chatbot and the Error: wrong type argument in Position

[vishnup...@gmail.com]

Hello all,

I tried chatbot demonstration. I had my Relex and Cog server running.  I got the Error "wrong type argument". 

guile> (nlp-parse john is generous")

guile> (process-query "Priya" "who is generous?")


Hello Priya, you said: "who is generous?"
You made an Interrogative SpeechAct
wrong-type-arg
(display Wrong type argument in position ~A: ~S (2 0) (0))
Sorry, I don't understand it

----------------------------------------------------------------

I also tried chatbot-psi 

I did the following steps.:
guile> (use-modules (opencog) (opencog nlp) (opencog nlp aiml) (opencog openpsi))
guile> (add-to-load-path "/home/vishnu/Documents/opencog_relatedPackages/opencog/opencog/nlp/chatbot-psi")
guile> (load-from-path "main.scm")
guile> (load-from-path "aiml-rules.scm")

guile> (aiml-get-response-wl (token-seq-of-sent "hello"))

ERROR: In procedure apply-smob/1:

ERROR: In procedure cog-type: Wrong type argument in position 1 (expecting opencog atom): "hello"
ABORT: wrong-type-arg

-----------------------------------------------------------------

Am i missing anything? how can i solve the problem?  Any guidelines would be very much  helpful. 

Thanks in advance.

Dunno. You may want to open a github report, and provide some additional details, like which modules you loaded, etc. 

This code is being hacked on almost every day; maybe something got broken recently.

ok Linas. I shall provide additional details in github. Thanks!

I tried chatbot demonstration also by installing https://github.com/hansonrobotics/HEAD. I did not compile and install the modules (such as atomspace, cogutils, opencog...) manually. It itself automatically installed all the modules required. But then also i got the following error.

guile> (process-query "Priya" "who is generous?")
Hello Priya, you said: "who is generous?"
You made an Interrogative SpeechAct

[Linas Vepstas]

That last bit is printed by  nlp/chatbot/bot-api.scm line 83 when an exception is caught. Right before that, it should print the actual exception -- if nothing else, it should print two newline characters.  Are you saying that there was no exception text printed? 

I just changed the code to print "Sorry, I caught an exception\n" instead of "Sorry, I don't understand it" just to make that clear.

Now it says, it caught an Exception, which is as follows:

guile> Hello luser, you said: "are you a bot"

You asked a Truth Query

I can't process truth query for now

guile> (nlp-parse "mary eats apple")

((SentenceNode "sentence@b2d9f1db-524d-4c79-a7e2-5e28f0db00b2")

)

guile> (nlp-parse "tom eats mango")

((SentenceNode "sentence@b3820f2c-5ae4-4029-ab0d-089d790ca0e2")

)

guile>    (process-query "luser" "who eats apple")

Hello luser, you said: "who eats apple"

You made an Interrogative SpeechAct

wrong-type-arg

(display Wrong type argument in position ~A: ~S (2 0) (0))

Sorry, I caught an exception

But what is this wrong type argument?

How can i fix this?

[Linas Vepstas]

well, its hard to guess where it is, without a backtrace.  You should add these lines to your `~/.guile` file:

```

(debug-enable 'backtrace)

;;; Record positions of source code expressions.

  (read-enable 'positions)

```

I believe that the above should be enough to pinpoint the issue.

--linas

[vishnup...@gmail.com]

My .guile file is as follows : 

(use-modules (ice-9 readline)) (activate-readline)

(debug-enable 'backtrace)

;;; Record positions of source code expressions.

(read-enable 'positions)

(add-to-load-path "/usr/local/share/opencog/scm")

(add-to-load-path ".")

(use-modules (opencog))

(use-modules (opencog nlp chatbot))

(use-modules (opencog query))

(use-modules (opencog exec))

(load-from-path "opencog.scm") 

But sill i did not get any backtrace! am i missing anything here?

[Linas Vepstas]

Sigh.  I guess the catch was suppressing the print.  The following will print this:

https://github.com/opencog/opencog/commit/251baccce6cb51bea92bdce5771d2be87fdd9e6b

This is the Backtrace.

[Leung Man Hin]

it is recommended to use the newer chatbot (chatbot-psi) via the `chat` commend, e.g. (chat "who is generous?"), or call it via the webui with HEAD running, thanks

Hmm. 

Man Hin, the process-query interfaces work fine for me, I cannot reproduce the above error. The stack trace points at line 76 of fuzzy.scm  as the source of the problem.  But then it says that its argument 2, and argument 2 is at line 100 

My guess is that setlinks is not an actual guile list, which is what append-map is expecting. Adding additional prints to this code might clarify the fault.

Why its broken only for Vishnu, and not for me, I don't know.

But using chat-bot psi, i thought, we can only ask pre-defined questions that are in aiml file?!  If i need to ask "who is generous", then in the scm file should be  there a question "who is generous" and it's corresponding answer ?!

      Nevertheless,  when i do (chat "what is ai"), it shows unbound variable: chat.

Things work fine for me too... Vishnu, could you double check if you are running all the latest codes, clean the cache (`rm -r ~/.cache/guile`), rebuild everything then try again and see if it works?
