TypeError: Couldn't build proto file into descriptor pool!

[XiaohanYa]

Hi,

I'm using CoreNLP Client from stanza to annotate my text, and I want to save my results. I used the following code to save my results. I think it works well but I encountered errors when reading in the result file.

with open(dir_path+'reproduced/corenlp/results.pb2', 'wb') as f:
    f.write(annotated_doc.SerializeToString())

When reading the file, I tried the following code. The corenlp-protobuf I installed is version 3.8.0.

from corenlp_protobuf import Document, parseFromDelimitedString

def readCoreNLPProtoFile(protoFile):
  with open('protoFile', 'rb') as f:
      buf = f.read()
  doc = Document()
  parseFromDelimitedString(doc, buf)
  return doc

However, I got the TypeError as follows. Could someone help me? Thanks in advance.

Are you using two separate libraries which both happen to use a protobuf to communicate with corenlp? Maybe there's a conflict, especially since the protobuf definitions aren't synced. I would recommend entirely using stanza instead, since stanza is actively being developed and has some better support in general for corenlp.
