Problems with data loading with Grakn 1.7.1

I have a migration script that I use to load data into Grakn via the Python driver with Grakn Core 1.6.2. This works.

I have recently downloaded 1.7.1, but when I run the same migration script I get the following error: 

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/grakn/service/Session/TransactionService.py", line 161, in send
    response = next(self._response_iterator)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/grpc/_channel.py", line 388, in __next__
    return self._next()
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/grpc/_channel.py", line 382, in _next
    raise self
grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with:
    status = StatusCode.INVALID_ARGUMENT
    details = ""
    debug_error_string = "{"created":"@1589227241.242279000","description":"Error received from peer ipv6:[::1]:48555","file":"src/core/lib/surface/call.cc","file_line":1055,"grpc_message":"","grpc_status":3}"
>

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "migrator.py", line 240, in <module>
    insertSchema(URI, KEYSPACE)
  File "/Users/johnnie/Documents/grain/insert.py", line 21, in insertSchema
    write_transaction.query(schema)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/grakn/client.py", line 131, in query

  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/grakn/service/Session/TransactionService.py", line 165, in send
    raise GraknError("Server/network error: {0}\n\n generated from request: {1}".format(e, request))

>

 generated from request: query_req {
[SCHEMA IS SHOWN HERE]
}

Any help is greatly appreciated.

You need to write

 pip install --upgrade grakn-client

Sources: python client api docs and pip install docs

(the --upgrade flag because it is already installed.)

Are you using the latest release of both the Python Grakn client and Grakn server? Grakn core 1.7 is not compatible with pre-1.7 clients.
