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.
