Unknown function registry: 'scorers' with spacy webservice with flask

i'm using spacy in conjunction with flask and anaconda to create a simple webservice. Everything worked fine, until today when i tried to run my code. I got this error and i don't understand what the problem really is. I think this problem has more to do with spacy than flask.

Here's the code:

@app.route('/en/<textstr>')
def eng(textstr):    
    nlp = spacy.load("en_core_web_trf")
    doc = nlp(textstr)
    for token in doc:
        print(token.text,list(token.morph), token.pos_,token.dep_)
        if token.pos_ == "VERB":
            print("This is a Verb: "+token.text_)
    return "Success"

When i enter http://127.0.0.1:5000/en/Hello%20my%20name%20is%20Stackoverflow i get this error message:

Can somebody help me please?

Solution

  • What you are getting is an internal error from spaCy. You use the en_core_web_trf model provided by spaCy. It's not even a third-party model. It seems to be completely internal to spaCy.

    You could try upgrading spaCy to the latest version.

    The registry name scorers appears to be valid (at least as of spaCy v3.0). See this table: https://spacy.io/api/top-level#section-registry

    The page describing the model you use: https://spacy.io/models/en#en_core_web_trf
