Mixin for triton
Parameters:
url: str
triton server ip and port.the most likely url will be "127.0.0.1:8001".
mode: str
The function of inference.
'grpc' protocol has 'infer'/'async_set'/'stream' functions.
'http' protocol only has 'infer' function.
The default value is 'infer'.
model_name: str
The name of the model to run inference.
The default value is 'pipline'.
protocol: str
Communication protocol between triton server and client.
The default value is 'grpc'.
