sa-logic not working
agorkiy opened this issue · 4 comments
Hi
sa-logic python app is not working in my case.
Started it on local computer and posted a request:
curl -X POST localhost:5000/analyse/sentiment --data '{"sentence": "test"}'
got this answer:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
And here is what have in terminal tab where python is running:
agorkiy@home:~/k8s-mastery/sa-logic/sa$ sudo python3 sentiment_analysis.py
- Serving Flask app "sentiment_analysis" (lazy loading)

Any thoughts - am I doing something wrong or there is a bug somewhere here?
In k8s-mastery/sa-logic/sa/requirements.txt file, change Flask version to 0.12.5 and do python3 -m pip install -r requirements.txt.
Make sure you're using Python version 3. Check by doing python --version or python3 --version.
Did, looks for me that nothing changed.

@agorkiy Are you passing request body correctly? Make sure you're passing request body with JSON object and sentence key. Can you share your cURL request?
@dhruvdutt
Yes, found mistake - forgot to add -H "Content-Type: application/json" in POST request.
Now it's working:
agorkiy@home:/k8s-mastery/sa-logic/sa$ curl -d '{"sentence": "I hate you!"}' -H "Content-Type: application/json" -X POST http://localhost:5000/analyse/sentiment
{
"polarity": -1.0,
"sentence": "I hate you!"
}
Thanks for help.
