Graphs Repository

Model server can deploy a pipelines of models and nodes for any complex and custom transformations. From the client perspective of behaves almost like a single model but it more flexible and configurable.

The model repository employing graphs is similar in the structure to classic models. It needs to include the collection of models used in the pipeline. It also require a MediaPipe graph definition file in .pbtxt format.

graph_models
├── graph.pbtxt
├── model.py
├── model1
│   └── 1
│       ├── model.bin
│       └── model.xml
├── model2
│   └── 1
│       ├── model.bin
│       └── model.xml
└── config.json

In can the graph includes python nodes, there should be included also a python file with the node implementation.
