My first guess is that the python bindings are broken, again. Both @noskill and @vsbogd use python regularly, maybe they know ...

[noskill]

it works:

python_atomspace = AtomSpace()
scheme_eval(python_atomspace, "(use-modules (opencog) (opencog exec))")
atomspace = scheme_eval_as('(cog-atomspace)')

[aivanouski]

it works:

python_atomspace = AtomSpace()
scheme_eval(python_atomspace, "(use-modules (opencog) (opencog exec))")
atomspace = scheme_eval_as('(cog-atomspace)')

Thank you! It works.
But happened new error:

Try cog-extract-recursive! with the exclamation mark at the end. I think it's needed. There is a backward-compatibility layer, without the exclamation mark, but perhaps it is not being loaded for some opaque reason. I will submit a pull request shortly.

Also, could someone please submit a pull req to patch up the telegram-bot?

[aivanouski]

I have fixed it by adding next config in python script:
scheme_eval(atomspace, '(primitive-load "/home/ubuntu/home/atomspace/opencog/scm/opencog.scm")')

[aivanouski]

After next dialog:

• Tom eats apples.
• Hello Andrei, you said: "Tom eats apples."
  You made a Declarative SpeechAct
• What does Tome eat?

It catch exception, In unknown file:

1. you wrote "What does Tome eat?" - try again without the "e"
2. the chatbot was very incomplete: if you look at bot-api.scm, it doesn't do much.
3. the code that is crashing, somewhere in sureal, is also unmaintained.

Are you good at programming? You might try to find what it is in sureal that is throwing an exception ...
