This feature allows adding custom partitioners by dynamically loading external libraries at runtime. + +This custom partitioner feature, enables users to write custom model partitioning strategies without compiling against all of MXNet header files and dependencies. When a library containing custom partitioners is loaded dynamically, the components found in the library will be re-registered in MXNet so that users can use those natively just like other built-in components. Review comment: I used the term "components" since we're still at the beginning of the doc and I wanted to use a general term for things before we dig into the nitty gritty details. Here components refers to the custom subgraph operator and partitioner that will be registered with the REGISTER_* macros. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
