Orchestration Configuration Example

The configuration file for creating a graph (graph.prototxt) is in proto format. In the following example, two graphs are created at the same time, multiple engines are created for each graph, and the mapping is configured.

To transfer a file, the following conditions must be met. Otherwise, the system transfers a string or number by default.

  • In the Linux operating system, the file must contain a relative path or an absolute path, for example, /home/1.txt or ../test/2.txt. Note: The string may be mistakenly considered as a file if it contains the "\" or "/" symbol. Therefore, do not use the symbols.
  • In Windows, the file must contain a relative path or an absolute path, for example: c:\1.txt or ..\test\2.txt. Note: The string may be mistakenly considered as a file if it contains the "\" or "/" symbol. Therefore, do not use the symbols.
