Using a credentials file when building a client for the prediction API fails. See the code sample below. From looking at the code, when initialising the PredictionServiceGrpcTransport class, the parent constructor in PredictionServiceTransport is called. The base constructor creates the credentials from the file (base.py, line 102). These credentials are then passed into the create_channel function (grpc.py, line 162) along with the credentials file, which eventually leads to the DuplicateCredentialArgs error.
