Illegal key type <type 'long'> for IntList

[Varvara Logacheva]

Hi, cdec users,

I hope this group is still active.

I've just started using cdec and only tried to reproduce an MT system building as written in tutorial (http://www.cdec-decoder.org/guide/tutorial.html).
On step 6 - grammar extraction for dev and test sets - the process stops due to an error "Illegal key type <type 'long'> for IntList".

I type in this command:
python -m cdec.sa.extract -c extract.ini -g dev.grammars -j 1 < dev.lc-tok.es-en > dev.lc-tok.es-en.sgm

and get this output:

TypeError: Illegal key type <type 'long'> for IntList

What causes this error? How can I fix it?

Btw I saw just the same error reported: https://github.com/redpony/cdec/issues/13
but it got no answer.

Thank you,

Varvara.

I committed a possible fix for this…

I am not sure why this is happening though: __len__ should return an `int` but it returns a `long`

Let us know if the change works for you!

Hi, Victor,

thank you for the answer.

Unfortunately, the corrected version crashed in the same point.

Are you sure that you re-installed the python module? (You might need to do: "rm -rf build" before that)

If yes, what is the error message now?

[Varvara Logacheva]

Hi,

sorry for the late answer.

yes, I've reinstalled the python module.
The error remained the same as the first time.
