Rasa: Testing error in rasa_nlu

[SATACHAKRA]

I got the latest version of rasa_nlu cloned from github.
I trained my model following the tutorial from here.
After trainning with a full demo-rasa.json file upon putting the following request:
"curl -X POST localhost:5000/parse -d '{"q":"I am looking for Chinese food"}' | python -m json.tool" from another cmd I simply get this error.

I have googled and searched evrything.
Why am I getting this error...what am i doing wrong.I installed from github.
have got a scipy sklearn-crfsuite for Entity extraction.

[SATACHAKRA]

Why is no one replying to this?

[bastiW]

maybe this is Windows specific

I'm using the bash on Windows and it is working well with rasa.

@SATACHAKRA thank you for submitting your issue. We are working hard to make rasa the best product we can. And while we care about all issues, our time is limited, so please have some patience. Thank you @bastiW for stepping in, we rely on the community to support each other!

Your problem seems to be encoding related, which might be caused by some windows default setting. If the bash solution didn't help, could you try adding the following header to your curl request?
-H "Content-Type: application/json; charset=utf-8"
So that it becomes
curl -X POST -H "Content-Type: application/json; charset=utf-8" localhost:5000/parse -d '{"q":"I am looking for Chinese food"}' | python -m json.tool

[SATACHAKRA]

Let me try this.

[SATACHAKRA]

@twerkmeister
It is still showing the same error.
`C:\Users\AppData\Local\Programs\Python\Python36\rasa_nlu>curl -X POST -H "Content-Type: application/json; charset=utf-8" localhost:5000/parse -d '{"q":"I am looking for flights to Rome."}' | python -m json.tool

I have prepared my own training set and want to create a flight booking mechanism.Training goes ok.
But still this error is shown.

[SATACHAKRA]

@bastiW-I dont want to shift to bash shell.
I have to make this work in widows environment as per client specifications.

[somnathkhamaru]

Try this
curl -i -X POST -H "Content-Type:application/json" -d "{\"q\": \"I am looking for Chinese food\", \"model\" : \"your_model_name\" }" http://localhost:5000/parse

I also had the same issue today . I ran Rasa_nlu for the 1st time today in windows.
This solved my issue @SATACHAKRA

No success.
Can someone point me in the right direction?

[wrathagom]

Maybe the same problem as #669?

curl -X POST "http://localhost:5000/parse" -d "{\"q\":\"I am looking for Chinese food\"}" | python -m json.tool

[somnathkhamaru]

@SATACHAKRA please use localhost ip like "127.0.0.1" in place of the word "localhost". I got same error , it was not able to recognise localhost.

so the command will be

curl -i -X POST -H "Content-Type:application/json" -d "{"q": "I am looking for Chinese food", "model" : "your_model_name" }" http://127.0.0.1:5000/parse

[SATACHAKRA]

@wrathagom
WORKING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Cool man..thanks.
Currently I am trying to get the intents with Python as shown in the tutorial.Results are coming.
But could you kindly suggest me any other place from where I can have more idea about using the rasa_nlu with python...apart from the documentation? My project is based on a flight booking chatbot.

[SATACHAKRA]

@somnathkhamaru
sorry brother but your code didn't work...maybe some issues with the environment.
Still thanks for the help.

@SATACHAKRA please join the gitter channel and ask for tutorials/etc there are several of us that have written different forms of tutorials and guides.
