OpBenchmarkListener

public OpBenchmarkListener(Operation operation,
                           @NonNull
                           @NonNull OpBenchmarkListener.Mode mode)

OpBenchmarkListener

public OpBenchmarkListener(Operation operation,
                           @NonNull
                           @NonNull OpBenchmarkListener.Mode mode,
                           long minRuntime)

Parameters:

operation - Operation to collect stats for

mode - Mode - see OpBenchmarkListener

minRuntime - Minimum runtime - only applies to Mode.SINGLE_ITER_PRINT. If op runtime below this: don't print

Method Detail

isActive

public boolean isActive(Operation operation)

Description copied from interface: Listener

Returns whether this listener is active during the given operation. If this returns false for the given operation, those listener methods will not be called.

operationStart

public void operationStart(SameDiff sd,
                           Operation op)

Description copied from interface: Listener

Called at the start of an operation, e.g. training or validation

Specified by:

operationStart in interface Listener

Overrides:

operationStart in class BaseListener

Parameters:

sd - The SameDiff instance

op - The operation being started

operationEnd

public void operationEnd(SameDiff sd,
                         Operation op)

Description copied from interface: Listener

Called at the end of an operation, e.g. training or validation

Specified by:

operationEnd in interface Listener

Overrides:

operationEnd in class BaseListener

Parameters:

sd - The SameDiff instance

op - The operation being started

preOpExecution

public void preOpExecution(SameDiff sd,
                           At at,
                           SameDiffOp op,
                           OpContext opContext)

Description copied from interface: Listener

Called just before each operation is executed (native code called, etc) - after all inputs etc have been set

Specified by:

preOpExecution in interface Listener

Overrides:

preOpExecution in class BaseListener

Parameters:

sd - The SameDiff instance

at - Current iteration/epoch etc

op - Operation that has just been executed

opExecution

public void opExecution(SameDiff sd,
                        At at,
                        MultiDataSet batch,
                        SameDiffOp op,
                        OpContext opContext,
                        INDArray[] outputs)

Description copied from interface: Listener

Called at the end of each operation execution

Note: Outputs will most likely be freed later, use detach() if you need to save it.

Specified by:

opExecution in interface Listener

Overrides:

opExecution in class BaseListener

Parameters:

sd - The SameDiff instance

at - Current iteration/epoch etc

batch - The batch's input data. May be null if not called with a batch

op - Operation that has just been executed

outputs - The output arrays for the just-executed operation
