Writing gRPC seldon query in Java and its dependencies

[rishikesh bansod]

Hi,

      I want to use gRPC calls when our model is deployed in seldon. Following is the code I got for python gRPC from seldon example.

def get_token():

    payload = {'grant_type': 'client_credentials'}

    response = requests.post(

                "http://{}:8080/oauth/token".format(SELDON_API_IP),

                auth=HTTPBasicAuth('oauth-key', 'oauth-secret'),

                data=payload)

    token =  response.json()["access_token"]

    return token

def grpc_request():

    token = get_token()

    datadef = prediction_pb2.DefaultData(

            names = ["a","b"],

            tensor = prediction_pb2.Tensor(

                shape = [3,2],

                values = [1.0,1.0,2.0,3.0,4.0,5.0]

                )

            )

    request = prediction_pb2.SeldonMessage(data = datadef)

    channel = grpc.insecure_channel("{}:5000".format(SELDON_API_IP))

    stub = prediction_pb2_grpc.SeldonStub(channel)

    metadata = [('oauth_token', token)]

    response = stub.Predict(request=request,metadata=metadata)

    print(response)

I want to convert same in Java for gRPC request. What will be equivalent code in Java and required dependencies for gRPC?

Thanks,
