Co-Reference Pipeline sample code is not working

[jungyitsai]

I use sample code from document-reference, but I get the error-message NodeIDAbsentError: Node 'None' is not in the tree. Do I misuse this sample code?

• sample code

  
  from ckipnlp.pipeline import CkipCorefPipeline, CkipDocument

pipeline = CkipCorefPipeline() doc = CkipDocument(raw='畢卡索他想，完蛋了')

Co-Reference

corefdoc = pipeline(doc) print(corefdoc.coref) for line in corefdoc.coref: print(line.to_text())

Sorry for my late response. The Co-Reference pipeline depends on CkipClassic Parser Client backend. To use the CkipClassic Parser Client backend, you need to

1. Register an account at http://parser.iis.sinica.edu.tw/v1/reg.exe
2. Set the environment variables $CKIPPARSER_USERNAME and $CKIPPARSER_PASSWORD to the username and password.

CkipClassic updated. https://github.com/ckiplab/ckip-classic/releases/tag/1.2.1

Now it will raise error if username/password is invalid.
