token.sentiment is only outputting 0.0

[Ibrokhimsadikov]

in any polarity token token.sentiement attribute is giving 0.0 score, why is that?

Thank you for any suggestion

The sentiment attribute isn't being automatically filled by any spaCy components - it's there for convenience in case you want to implement sentiment analysis using a rule-based or machine learning approach (using textcat). There's a simple example in the docs for a rule-based approach: https://spacy.io/usage/rule-based-matching#example3.

Thank you @svlandeg for your prompt reply, but still I not sure if I understood your solution

This functionality doesn't work out-of-the box. You will have to train a sentiment analysis classifier first, and store its results in the sentiment attribute, for it to be useful.
