Failed to run demos due to JSONDecodeError

[always19]

I'm interested in representing semantic of sentences so that I want to try yours. I succeeded to run only demo1.python

All other demos seem not to work due to the following JSONDecodeError

PPP-QuestionParsing-Grammatical/demo$ python3 demo3.py > demo.dot
Where is the capital of Belgium?
Traceback (most recent call last):
  File "demo3.py", line 29, in <module>

  File "demo3.py", line 17, in parse
    result = r.json()['sentences'][0]

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I tried pip install jsonrpclib. Then, now I can't even run the corenlp server.

Scripts$ CORENLP="stanford-corenlp-full-2014-08-27" CORENLP_OPTIONS="-parse.flags \" -makeCopulaHead\"" python3 -m corenlp -p 9000

    from jsonrpclib.SimpleJSONRPCServer import SimpleJSONRPCServer
ImportError: No module named 'jsonrpclib'

Any ideas?

Regarding the ImportError: the right command is pip3 install jsonrpclib. pip is for Python 2, not Python 3. Installing it for Python 2 should not have triggered the error on Python 3, though.

Ping @Ezibenroc, regarding the first error.

From this command you used:

Scripts$ CORENLP="stanford-corenlp-full-2014-08-27" CORENLP_OPTIONS="-parse.flags \" -makeCopulaHead\"" python3 -m corenlp -p 9000

I think you are using an outdated version of CoreNLP. Since #149, we use the server provided by CoreNLP. Prior to that, the library did not have any server, so we had to wrap it with some Python code.

You can use dependencies.sh to install the correct version and launch the server. I updated the README to add this instruction.

Thank you! I ran demo1, 2, 3, (4).py successfully for now.
