when I ran codes in simple.py, still got the error:

schema = “”"
… type Person {

“”"… … … … … … … …

client.alter(pydgraph.Operation(schema=schema))
Traceback (most recent call last):

I’m wondering if this is imcompatible API problem caused by versions I’m using.

after upgrade dgraph to version 1.1.1, problem vanished.
