case class BroadcastGlobalVariablesHook extends api.tf.learn.Hook with Product with Serializable

Hooks that will broadcast all global variables from root rank to all other processes during initialization.
Hooks that will broadcast all global variables from root rank to all other processes during initialization.
This is necessary to ensure consistent initialization of all workers when training is started with random weights or restored from a checkpoint.

def allReduce[O <: OutputLike](value: O, average: Boolean = true, deviceDense: String = "", deviceSparse: String = ""): O

Performs an all-reduce operation on value.
Performs an all-reduce operation on value.
This function performs a bandwidth-optimal ring all-reduce on the input tensor. If the input is indexed slices, then this function instead does an all-gather on the values and the indices, effectively doing an all-reduce on the represented tensor.
value
Value to reduce.
average
If true, the average over all ranks will be computed.
deviceDense
Device to use for dense tensor reduce operations. Defaults to a GPU if Horovod was built with HOROVOD_GPU_ALLREDUCE.
deviceSparse
Device to use for sparse tensor reduce operations. Defaults to a GPU if Horovod was built with HOROVOD_GPU_ALLGATHER.
returns
Reduced tensor value.

def broadcastGlobalVariables(rootRank: Int): Op

Broadcasts all global variables from root rank to all other processes.
Broadcasts all global variables from root rank to all other processes.
rootRank
Rank of the process from which the global variable values will be broadcasted to all other processes.
returns
Created broadcast op.
