Functions

hxtorch.spiking.run(experiment: hxtorch.spiking.experiment.Experiment, runtime: Optional[int, None]) → Optional[hxtorch.spiking.execution_info.ExecutionInfo, None]

Execute the given experiment.

TODO: Why is this a standalone function?

Parameters

• experiment – The experiment representing the computational graph to be executed on hardware and/or in software.

• runtime – Only relevant for hardware experiments. Indicates the runtime resolved with experiment.dt.
