Hi,
I am trying with DUC-ResNet101 (from ONNX model zoo) and when I want to start server with the following line of code:
multi-model-server --models duc=https://s3.amazonaws.com/model-server/model_archive_1.0/onnx-duc.mar
I get this error:
command not found: multi-model-server

I am working on Mac terminal.

How did you install mms? From source or pip?
