Problems with syntaxnet_wrapper

[fiammettaAtGit]

Hi. I just installed your code but I'm just experiencing problems with starting it. After installing all the needed dependencies (flask, swig ui, etc..), now I have problem while running the flask_server.py to run service over 7000 port. Please, could you provide me more information about correctly installing syntaxnet_wrapper, cause I followed the provided instructions, but it doesn't work!:-((

thanks

Hi. I just installed your code

Great! Thank you!

now I have problem while running the flask_server.py to run service over 7000 port.

What is your problem? Do you have any error message?

PS: installation is much easier with docker. syntaxnet_api is very painful to install "by hand".

Hello, I was finally successful in installing your code. It works great! thank you!

Let me ask you something else:

I would like to invoke your server by a Java Application, in order to submit sentences non by hand, but pulling it from a text file.

Is there any API I could use to do that?

I'm just thinking to take in input the tex-file containing the sentences list and splitting them, in order to submit a single sentence request.

But, can you provide me an API (if it possible), to submit a HTTP POST request to your server instead of using the GUI? Thanks in advance Fiammetta

Great! Congrats!

Is there any API I could use to do that?

Yes, just POST to https://MY_INSTANCE/v1/parsey-universal-full with the text to parse in the request body and the language code in the "Content-Language" HTTP header.

Example with cUrl: curl -X POST --header 'Content-Type: text/plain; charset=utf-8' --header 'Content-Language: en' -d 'Where is Paris' 'https://HOST/v1/parsey-universal-full'

Thank you so much for your quick answers! I'm just fixing my problems as they come to me!! Well, I just wrote my Java code following your instructions. HTTP POST message, sent to your online server url ("http://syntaxnet.askplatyp.us/v1/parsey-universal-full"), works great!!

Now, I'm just trying to forward the same request to my local instance, setting the url to: "https://127.0.0.1:7000/v1/parsey_universal_full".... But I'm just receiving 405 response code for bad request syntax. Have you ever got problems like this one before? Thanks in advance, Fiammetta

Do you experienced problems like this before?

No, did not had such problem. Is the UI of your instance working or not?

[fiammettaAtGit]

Actually, the UI of my local instance does not work well. UI starts but when I try to submit any request, in any language, I got a 0 code response:

Here is the details provided from my local UI (it seems to try to connect anyway to your remote instance..).

Request URL

http://syntaxnet.askplatyp.us/v1/parsey-universal-full

Response Body

no content

Response Code

0

Response Headers

{ "error": "no response from server" }

Here is the command line response I got when I tried to submit a request on my local instance UI:

i# python flask_server.py INFO:werkzeug: * Running on http://127.0.0.1:7000/ (Press CTRL+C to quit) INFO:werkzeug:127.0.0.1 - - [23/May/2017 12:01:08] "GET / HTTP/1.1" 302 - INFO:werkzeug:127.0.0.1 - - [23/May/2017 12:01:08] "GET /v1 HTTP/1.1" 200 - INFO:werkzeug:127.0.0.1 - - [23/May/2017 12:01:09] "GET /v1/swagger.json HTTP/1.1" 200 -

Could you send me the response when you send a request to your instance from the command line (or any programming language?)

[fiammettaAtGit]

Hi, sorry for answering only now. Here is what I usually do:

1. As First, I just start my local instance for the HTTP Server from command line; here is the output (it seems to be ok):

root@fiammetta-Veriton-M2631G:/home/fiammetta/swrap/syntaxnet-api# python flask_server.py INFO:werkzeug: * Running on http://127.0.0.1:7000/ (Press CTRL+C to quit)

I observed problems also by using the UI of my local instance. In fact, filling in my simple sentence "My cat is always hungry" in the UI form, I just got this response:

Response Headers

{ "error": "no response from server" }

In the corresponding terminal windows, these are the message displayed:

INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:14:55] "GET / HTTP/1.1" 302 - INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:14:55] "GET /v1 HTTP/1.1" 200 - INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:14:55] "GET /v1/swagger.json HTTP/1.1" 200 -

Otherwise, if I run my Java Code, building a Post request addressed to the following url: url = new URL("http://127.0.0.1:7000/v1/parsey_universal_full"); I just got a lot of Java Exception Message Codes and these messages in the command line windows:

INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:20:03] "POST /v1/parsey_universal_full HTTP/1.1" 404 - INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:20:03] "POST /v1/parsey_universal_full HTTP/1.1" 404 - INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:20:03] "POST /v1/parsey_universal_full HTTP/1.1" 404 - INFO:werkzeug:127.0.0.1 - - [26/May/2017 16:20:03] "POST /v1/parsey_universal_full HTTP/1.1" 404 -

Hi! I believe I've found why you get a 404 error: You are trying to use '/v1/parsey_universal_full' instead of '/v1/parsey-universal-full' (with "_" instead of "-")
