encode(to:feeds:targetTensors:targetOperations:executionDescriptor:)

Encodes the graph for the given feeds to returns the target tensor values, ensuring all target operations also executed.

Declaration

func encode(to commandBuffer: MPSCommandBuffer, feeds: [MPSGraphTensor : MPSGraphTensorData], targetTensors: [MPSGraphTensor], targetOperations: [MPSGraphOperation]?, executionDescriptor: MPSGraphExecutionDescriptor?) -> [MPSGraphTensor : MPSGraphTensorData]

Parameters

  • commandBuffer:

    commandBuffer passed to exectute the graph on, it is an MPSCommandBuffer, commitAndContinue might be called, please don’t rely on underlying MTLCommandBuffer to remain uncommitted.

  • feeds:

    Feeds dictionary for the placeholder tensors.

  • targetTensors:

    Tensors for which the caller wishes MPSGraphTensorData to be returned.

  • targetOperations:

    Operations to be completed at the end of the run.

  • executionDescriptor:

    ExecutionDescriptor to be passed in and used.

Return Value

A valid MPSGraphTensor : MPSGraphTensorData dictionary with results synchronized to the CPU memory if MPSGraphOptionsSynchronizeResults set.

Discussion

This call is asynchronous and will return immediately if a completionHandler is set.
